Abstract:
We have combined the Kepler Eclipsing Binary Catalogue with
information from the HES (Everett et al., 2012PASP..124..316E 2012PASP..124..316E), KIS
(Greiss et al, 2012AJ....144...24G 2012AJ....144...24G, Cat. J/AJ/144/24) and 2MASS (Cat.
II/246) photometric surveys to produce spectral energy distribution
fits to over 2600 eclipsing binaries in the catalogue over a
wavelength range of 0.36-2.16Å. We present primary (T1) and
secondary (T2) stellar temperatures, plus information on the stellar
radii and system distance ratios. The derived temperatures are on
average accurate to 370K in T1 and 620K in T2. Our results improve on
the similarly derived physical parameters of the Kepler Input
Catalogue through consideration of both stars of the binary system
rather than a single star model, and inclusion of additional U-band
photometry. We expect these results to aid future uses of the Kepler
eclipsing binary data, both in target selection and to inform users of
the extremely high-precision light curves available. We do not include
surface gravities or system metallicities, as these were found to have
an insignificant effect on the observed photometric bands.
Description:
Catalogue, which includes temperature and stellar radius information
for the stars of the Kepler Eclipsing Binary Catalogue. For full
details see the publication.
