###### Abstract

A study of the host stars to exoplanets is important to understanding their
environment. To that end, we report new speckle observations of a sample of
exoplanet host primaries. The bright exoplanet host HD 8673 (= HIP 6702) is
revealed to have a companion, although at this time we cannot definitively
establish the companion as physical or optical. The observing lists for planet
searches and for these observations have for the most part been pre-screened
for known duplicity, so the detected binary fraction is lower than what would
otherwise be expected. Therefore, a large number of double stars were observed
contemporaneously for verification and quality control purposes, to ensure the
lack of detection of companions for exoplanet hosts was valid. In these
additional observations, ten pairs are resolved for the first time and sixty
pairs are confirmed. These observations were obtained with the USNO speckle
camera on the NOAO 4m telescopes at both KPNO and CTIO from 2001 to 2010.

##  1 Introduction

As discussed in Paper 1 of this series (Roberts et al. 2011) a study of the
host stars to exoplanets is essential if we wish to understand the environment
in which those planets formed. Further, the star’s luminosity, distance, mass,
and other characteristics are fundamentally related to the determination of
the planets mass and size. Determining these parameters directly for the host
star as opposed to using a template of the canonical stellar class and type
will produce more accurate and precise planetary determinations. As part of
this effort we herein report new speckle observations of a large sample of
exoplanet host primaries.

Binaries affect the formation and stability of planetary systems, as their
long-term relationship must be hierarchical. Generally speaking, based on the
precepts of Harrington (1981) if the ratio of semimajor axes is 4:1 or
greater, an exoplanet in a stellar binary is dynamically stable. Dynamically
permitted systems include the more commonly detected configuration of
planet(s) orbiting one stellar component of a sufficiently wide-orbit binary
in a hierarchical arrangement, and the harder-to-detect circumbinary
configuration of planet(s) in a wide orbit around a close stellar binary (see
Raghavan et al. 2006, especially §6.1). That said, Raghavan et al. (2010) in
their statistics updating and improving upon Duquennoy & Mayor (1991), find
that while the frequency of single stars is the same, the number of companions
has increased through instrumental and technique enhancements. Due to the
presence of stellar companions, one might imagine the environment of binary
stars to be a rich one for substellar companions. However, dynamical effects
should eject companions not found in hierarchical orbits. In any event, as
conducive as this environment might be to companions, this is not reflected in
the list of known planet hosts, however. This is due entirely to selection
effects; because of the complexities of disentangling stellar companions from
small planetary signatures, the observing lists for planet searches have for
the most part been pre-screened for known duplicity, so the detected binary
fraction is lower than what would be expected.

In addition to binary stars that are gravitationally bound, there are optical
doubles which are merely chance alignments of unrelated stars. Although they
do not contribute dynamically to the system, close optical pairs do contribute
light to the system, which should be accounted for in system analysis. While
photometric analysis of binary systems can infer $``$third” light in the
system, radial velocities or periodic variation in other astrometric
parameters (for example, the Hipparcos acceleration solutions), would not give
evidence of these companions. Optical pairs would best be found by direct
imaging or interferometric analysis.

##  2 Speckle Observations

All of these observations were obtained as part of other observing projects,
for example, analysis of white, red and subdwarfs (Jao et al. 2009), G dwarfs
(§5.3.6 of Raghavan et al. 2010), or Massive stars (Mason et al. 2009), some
of which are still in developmental and/or data collection stages. Unpublished
observations of exoplanet host stars were extracted from these data and are
presented here. The instrument used for these speckle observations was the
USNO speckle interferometer, described most recently in Mason et al. (2009).

Speckle Interferometry is a single filled-aperture interferometric technique
where the $``$speckles” of a pair of nearby stars, induced by atmospheric
turbulence, constructively interfere. Reduced by simple autocorrelation
methods, in the resulting image the binary or double star geometry is the
predominant structure when compared with the other uncorrelated pairings. It
is capable of resolving pairs to the resolution limit of the telescope in
question up to size of the observation field (typically, $\sim$1$\farcs$5), as
long as the pairs have magnitude differences of less than about three.

Calibration of the KPNO data was accomplished through the use of a double-slit
mask placed over the “stove pipe” of the 4-m telescope during observations of
a bright known-single star (as described in Hartkopf et al. 2000). This
application of the Young’s double-slit experiment allowed determination of
scale and position angle zero points without relying on binaries themselves to
determine calibration parameters. Multiple observations through the slit mask
(during five separate KPNO runs from 2001 to 2008) yielded mean errors of
0$\fdg$11 in the position angle zero point and 0.165% in the scale error.
These “internal errors” are undoubtedly underestimates of the true errors for
these observations, because these calibration tests were made on stars that
were brighter and nearer the zenith than science stars. Total errors are
likely 3–5$\times$ larger than these internal errors.

Because the slit-mask option is not available on the CTIO 4-m telescope, we
calibrated the Southern Hemisphere data using observations of numerous well-
observed wide equatorial binaries obtained at both the KPNO and CTIO
telescopes. Published orbital elements for these pairs were updated as needed,
using the recent KPNO and published measures, then predicted $\rho$ and
$\theta$ values from those orbits deemed of sufficiently high quality were
used to determine the CTIO scale and position angle zero points. The
calibration errors for these southern observations were (not surprisingly)
considerably higher than those achieved using the slit mask. Mean errors for
five CTIO runs from 2001 to 2010 (as well as a 2001 KPNO run lacking slit mask
data) were 0$\fdg$67 in position angle and 1.44% in scale. These errors are
likely overestimated, because we have assumed that the calibration binaries
have perfect orbits, and any offsets are incorporated into the errors.

##  3 Results

Following generation of the Directed Vector Autocorrelation (Bagnuolo et al.
1992), the $``$DVA” is background subtracted through boxcar subtraction and
the sharp central peak which corresponding to the zeroth order speckles
correlating with themselves is clipped. Companions in the resulting DVA are
then readily apparent as peaks several sigma above the background.

Of the 118 exoplanet hosts we observed only one, HIP 6702 showed signs of a
companion and is discussed in Section 3.1 and listed in Table 1. The null
results are listed in Table 2, a list of single star detections. In the table,
Column (1) gives the Hipparcos number, Column (2) the HD Catalog number,
Column (3) lists other common designations, Column (4) is the epoch of
observation, and Column (5) identifies the telescope (C = Cerro Tololo 4m, K =
Kitt Peak 4m). For all of these observations no companion was detected within
the ranges $\Delta$mV $<$ $3$, and $0\farcs 03~{}<~{}\rho~{}<~{}1\farcs 5$.

Table 1 lists the observations for this new detection. Column (1) gives the
precise position of the system, Column (2) is the Washington Double Star
Catalog (hereafter, WDS; Mason et al. 2001) identifier, and Column (3) lists
the discovery designation, here the WSI (= Washington Speckle Interferometry)
number. Column (4) gives the Hipparcos number of the primary as a cross-
reference. Column (5) gives the epoch of observation, and Columns (6) and (7)
provide the relative astrometry. Column (8) lists a crude estimate of the
magnitude difference of the pair in the V band (the listed number is paired
with the more reliable observation). This estimate is probably only good to
$\pm 0.5\,mag$. Column (9) provides the separation in astronomical units,
based on the Hipparcos parallax and this angular separation assuming a face-on
orbit.

The resulting multiplicity fraction is extremely low, but artificially so.
Observation of known binaries is a prime goal of the USNO speckle program and
some of these pairs had been previously published (e.g., HD 28305 in Mason et
al. 2009). Others which were known but whose motions were not especially
compelling (e.g., HD 50583 in Mason et al. 2011) were observed with our 26in
refractor in Washington and those which do have a compelling individual story
to tell unrelated to exoplanets are in preparation (Farrington et al. 2012). A
simplistic multiplicity determination of this limited result
($=~{}\frac{1}{118}$) is therefore not a meaningful number.

###  3.1 New Double Star : HIP 6702

Of all the exoplanet hosts which have been serendipitously observed, all were
unknown as close visual doubles and only one of the host stars, HIP 6702 (= HD
8673) appeared double in directed vector autocorrelations on both times it was
observed. The classification of HIP 6702 as an exoplanet is based upon
Hartmann et al. (2010) who, using iodine-cell radial velocity measurements,
detected a companion with a $Msin~{}i$ of 14.2 Mj with a period of 1634$\pm$17
days and an eccentricity of 0.723$\pm$0.016. The relative astrometric measures
of this resolved pair are provided in Table 1. Given the small number of
measures presented in Table 2, the pair, while a visual double star, is not
necessarily a binary system. Verification of physicality for the new companion
to HIP 6702 can be accomplished several ways, among them color-magnitude,
proper motion and/or kinematic analysis. The speckle interferometry observable
of relative position establishing kinematic-physical (i.e., Keplerian) motion
requires at least three measures. So, while close proximity can be a powerful
argument for physicality, it is by no means definitive (c.f., $\iota$ Ori,
§5.1 of Mason et al. 2009). Nevertheless, even a companion which is only
nearby in the angular sense should be considered in any detailed analysis of
the star, as it will contribute to the photometric signature of the examined
target. Such is the case for HIP 6702, which was recently reported as a sub-
stellar companion (Hartmann et al. 2010).

Among the possible interpretations of the new speckle companion two stand out:
first, the companion is a not-physically associated line-of-sight companion
and second, it is the companion detected in Hartmann et al. (2010).

####  3.1.1 Physical Companion?

Hipparcos produced many types of double star solutions. The one which can be
most easily compared to other detection techniques and the most common are
those where the relative parameters ($\rho$, $\theta$) are presented. The
speckle interferometry measures presented in Table 1 are both near the
Hipparcos $``$C” code double star solution cutoff (0$\farcs$082 for HDS 446 =
HIP 27151). The other Hipparcos double star solutions may not be applicable
here. Some depend upon a priori orbital information (O code), system dynamics
in the plane of the sky (G code), variability (V code) or unknown parameters
(X and/or S code). In any event, the lack of Hipparcos detection is a
condition which is neither necessary nor sufficient to establish that the
Hartmann et al. (2010) companion is not-stellar.

However, if the two Table 1 measures represent relative measures of the
Hartmann et al. (2010) pair, the inclination must be extremely low. Assuming a
near zero inclination the mean separation of 0$\farcs$098 would approximate
the angular semi-major axis (a′′ = 0$\farcs$098$\pm$0$\farcs$011). Given this,
the Hipparcos parallax of 26.14$\pm$0.79 mas and the Hartmann et al. period of
1634$\pm$17 days, a mass sum of 2.63$\pm$0.92 M⊙ is obtained, which is not
unreasonable for two similar F dwarf stars, although the error is quite large,
primarily due to the uncertainty in a′′. The length of time between the two
speckle observations represents 1.47$\times$ the Hartmann et al. period. The
two measures of angular position represent $(0.497~{}or~{}0.503)+n$
revolutions of the system (depending on direction of rotation) which is very
similar to the Hartmann et al. period when $n=1$.

Given the estimated dynamic range ($\Delta$mV = $2.3\pm 0.5$) and assuming the
fainter limit and spectral type of the primary this would make the secondary
close to a K2V. Using the canonical mass of a K2V in $M~{}sin~{}i=14.2M_{j}$
gives an inclination of 1$\fdg$02\. Using this inclination with $a~{}sin~{}i$
from Hartmann et al. (2010) gives a semi-major axis of 0$\farcs$168 which is
consistent with the Table 1 results.

####  3.1.2 or Optical Companion?

Since the interferometric companion to HIP 6702 has been observed so few
times, establishing the companion as optical or physical is not possible. The
proper motion of the primary is 0$\farcs$25/yr ($\alpha$=0$\farcs$236/yr,
$\delta$=$-$0$\farcs$085/yr). From the relative positions in Table 1, the
proper motion of the companion would be an even higher at 0$\farcs$276/yr. If
linear motion is assumed and reasonable errors are applied it is possible to
determine where the companion would be at some date in the future. In Figure 1
this determination is performed assuming errors slightly larger than nominal
for the two speckle interferometry measures: $\Delta\theta=1\fdg 0$,
$\Delta\rho/\rho=1.0\%$ The predicted position for 2012 through 2015 are
plotted as error boxes. Again, assuming linear motion from the two speckle
points, a separation of 0$\farcs$37 and a position angle of 255∘ is determined
for 1991.25, which would be well within the capabilities of the Hipparcos
satellite (ESA 1997).

Figure 1: A “motion characterization” system plot for HIP 6702 (= WSI 96) with
small filled circles indicating the 2001 and 2007 speckle measures from Table
1. Scales are in arcseconds, and in each figure the large shaded circle
represents the V band resolution limit of a 4m telescope. The four small error
boxes in each figure indicate the predicted location of that pair’s secondary
in 2012.0, 2013.0, 2014.0, and 2015.0, assuming the motion is linear and all
speckle measures are characterized by errors of $\Delta\theta=1\fdg 0$,
$\Delta\rho/\rho=1.0\%$. Finding the double within a box appropriate to the
observation date would be a strong indication that the relative motion of the
pair is linear (that is, just motion from an unrelated field star due to
proper motion differences). The H indicates where the companion would have
been at 1991.25, at the Hipparcos epoch.

##  4 Future Observing

Due to the relatively even distribution of targets not yet observed by speckle
interferometry, one observing run in each semester and each hemisphere will be
necessary in order to observe all remaining exoplanet host stars. However, the
target list for each of the four runs will be slight, less than one hundred
stars each. With an approximately equal number of quality control and
equatorial scale calibration pairs, each observing run could easily be
completed in 2-3 nights. Priority would obviously be given to targets not
observed before. Those observed by other speckle interferometric groups would
be next priority so they all have a common reduction algorithm. Figure 2 is an
Aitoff plot of targets from the list of known exoplanet host stars taken from
the NStED111http://nsted.ipac.caltech.edu/cgi-bin/bgServices/nph-bgExec,
extracted 12 April 2011 database and gives their observation status.

Figure 2: Aitoff projection of all 444 targets. Filled circles ($N=114$) are
those listed in Table 2. Open circles ($N=27$) are those observed by CHARA or
USNO with an ICCD and reduced with the DVA method. Asterisks ($N=11$) are
those observed by other interferometry groups, and an $``$X” ($N=292$) are
those which have yet to be observed. A valid speckle measure is only counted
if it was obtained on a 4m class telescope.

nights on the 4-m Mayall telescope during our January 2001 run. While we were
hampered by poor weather, this additional allocation of time certainly helped
us achieve a greatly enhanced completion fraction. A special thank you is also
given to Hal Halbedel, who operated the telescope on all or part of each of
these new KPNO runs and was instrumental in the slit-mask work done at KPNO.

##  Appendix A Additional Measures of Known Pairs

Due to the high incidence of single stars among the exoplanet hosts, a
substantial number of double stars were observed contemporaneously with the
exoplanet host observations to ensure that the observing conditions and
detection capabilities given above were met. Additional measures of known or
suspected doubles were made as time permitted. Table A1 lists 549 mean
positions for 485 known systems. Column (1) is the WDS identification
(arcminute coordinate), Column (2) lists the Discovery Designation, and Column
(3) provides the Hipparcos number. Column (4) gives the epoch of observation,
and Columns (5) and (6) provide the relative astrometry. Column (7) contains
the notes for these systems. Also found in in table are ten pairs resolved for
the first time and sixty pairs which are here confirmed; estimated magnitude
differences for the new pairs (when available) are listed in the Notes column.
