The Occurrence Rate of Hot Jupiters in the Kepler Field

Abstract:
Using the latest Kepler data, we employ Bayesian statistical methods to measure an overall Hot Jupiter (HJ) occurrence rate of 5.8 0.6 per thousand stars. We look for a deficit of HJs around cool stars with convective envelopes. Winn et al. (2010) suggest that HJs orbiting cool stars should be lost to tidal interactions with the stellar convective envelope. However, we find a slight decrease in occurrence rate around hotter stars, which have less massive convection zones. This suggests that orbital decay caused by tidal interactions with stellar convective envelopes does not typically lead to the destruction of HJs over stellar main sequence lifetimes.
