The true stellar parameters of the Kepler target list
Abstract
We present results of a population synthesis study of the Kepler field. We adapted BiSEPS, a code that includes a fully self-consistent treatment of single and binary star evolution, to generate a sample of synthetic stars that represents the Kepler Input Catalogue (KIC). By subjecting this synthetic sample to the same target selection criteria that defined the actual Kepler target list we obtain a synthetic target list. We analysed the synthetic target list in turn with the methods of the Kepler Stellar Classification Project (SCP), to obtain SCP-derived stellar parameters. From this we find significant differences between the actual physical stellar parameters and those derived by the SCP of the stars in the synthetic sample. For a main sequence (MS) star, we find on average a ∼ 3% increase in stellar radius and a consequent ∼3% overestimate of the radius for any transiting exoplanet, when considered over the whole target list.
