Abstract:
We present a large sample of stellar rotation periods for Kepler
Objects of Interest, based on three years of public Kepler data. These
were measured by detecting periodic photometric modulation caused by
star spots, using an algorithm based on the autocorrelation function
of the light curve, developed recently by McQuillan, Aigrain & Mazeh
(2013). Of the 1919 main-sequence exoplanet hosts analyzed, robust
rotation periods were detected for 737. Comparing the detected stellar
periods to the orbital periods of the innermost planet in each system
reveals a notable lack of close-in planets around rapid rotators. It
appears that only slowly spinning stars with rotation periods longer
than 5-10 days host planets on orbits shorter than 2 or 3 days,
although the mechanism(s) that lead(s) to this is not clear.
Description:
We used the list of the KOIs and their parameters from the NASA
Exoplanet Archive (NEA; Akeson et al. 2013PASP..125..989A 2013PASP..125..989A) of 2013 May
22. The effective temperatures and surface gravities used in this work
come from the Kepler Input Catalog (KIC; Brown et al. 2011,
J/AJ/142/112) or where available from Dressing & Charbonneau (2013,
J/ApJ/767/95). For 47 stars in the sample that are missing KIC values
for logg and Teff, we used those provided in the NEA.
The public release 14 quarter 3-14 (Q3-Q14) light curves for these
targets are publicly available and were downloaded from the Kepler
mission archive.
