Catalog Service: Velocitometry transit of KOI-13
Description
We report the discovery of a new stellar companion in the KOI-13 system. KOI-13 is composed of two fast-rotating A-type stars of similar magnitude. One of these two stars hosts a transiting planet discovered by Kepler. We obtained new radial velocity measurements using the SOPHIE spectrograph at the Observatoire de Haute-Provence that reveal an additional companion in this system. This companion has a mass of between 0.4M_{sun}_ and 1M_{sun}_ and orbits one of the two main stars with a period of 65.831+/-0.029-days and an eccentricity of 0.52+/-0.02.
