Why is there a dearth of close-in planets around fast-rotating stars?

TEITLER S. and KONIGL A.

Abstract (from CDS):

We propose that the reported dearth of Kepler objects of interest (KOIs) with orbital periods Porb ≲ 2-3 days around stars with rotation periods Prot ≲ 5-10 days can be attributed to tidal ingestion of close-in planets by their host stars. We show that the planet distribution in this region of the log Porb-log Prot plane is qualitatively reproduced with a model that incorporates tidal interaction and magnetic braking as well as the dependence on the stellar core-envelope coupling timescale. We demonstrate the consistency of this scenario with the inferred break in the Porbdistribution of close-in KOIs and point out a potentially testable prediction of this interpretation.
