Abstract:
The NASA Kepler mission has revolutionized time-domain astronomy and
has massively expanded the number of known extrasolar planets.
However, the effect of wide multiplicity on exoplanet occurrence has
not been tested with this data set. We present a sample of 401 wide
multiple systems containing at least one Kepler target star. Our
method uses Pan-STARRS 1 and archival data to produce an accurate
proper motion catalogue of the Kepler field. Combined with Pan-STARRS
1 SED fits and archival proper motions for bright stars, we use a
newly developed probabilistic algorithm to identify likely wide binary
pairs which are not chance associations. As byproducts of this we
present stellar SED templates in the Pan-STARRS 1 photometric system
and conversions from this system to Kepler magnitudes. We find that
Kepler target stars in our binary sample with separations above
6arcsec are no more or less likely to be identified as confirmed or
candidate planet hosts than a weighted comparison sample of Kepler
targets of similar brightness and spectral type. Therefore we find no
evidence that binaries with projected separations greater than 3000au
affect the occurrence rate of planets with P<300d around FGK stars.
Description:
We present a proper motion survey of the Kepler field. We combine
archival datasets from wide-field public surveys and target UKIRT
observations with new Pan-STARRS 1 astrometry to produce accurate
proper motions for Kepler target stars.
This enables us to combine the excellent astrometric accuracy of a
modern CCD-based survey with the long time baseline of archival
plate data. We then use our Pan-STARRS 1 plus archival data proper
motion catalogue, along with SED fits using Pan-STARRS 1 and 2MASS
photometry, to select a population of wide binary pairs where at least
one component is a Kepler target star. We then use these binaries to
test whether wide binarity has an effect on exoplanet occurrence.
