Abstract:
We analyzed three years of data from the Kepler space mission to
derive rotation periods of main-sequence stars below 6500K. Our
automated autocorrelation-based method detected rotation periods
between 0.2 and 70 days for 34030 (25.6%) of the 133030 main-sequence
Kepler targets (excluding known eclipsing binaries and Kepler Objects
of Interest), making this the largest sample of stellar rotation
periods to date. In this paper we consider the detailed features of
the now well-populated period-temperature distribution and demonstrate
that the period bimodality, first seen by McQuillan et al.
(2013MNRAS.432.1203M 2013MNRAS.432.1203M) in the M-dwarf sample, persists to higher
masses, becoming less visible above 0.6M☉. We show that these
results are globally consistent with the existing ground-based
rotation-period data and find that the upper envelope of the period
distribution is broadly consistent with a gyrochronological age of
4.5Gyr, based on the isochrones of Barnes (2007ApJ...669.1167B 2007ApJ...669.1167B),
Mamajek, & Hillenbrand (Cat. J/ApJ/687/1264) and Meibom et al.
(Cat. J/ApJ/695/679). We also performed a detailed comparison of our
results to those of Reinhold et al. (Cat. J/A+A/560/A4) and Nielsen et
al. (Cat. J/A+A/557/L10), who measured rotation periods of field stars
observed by Kepler. We examined the amplitude of periodic variability
for the stars with detection rotation periods, and found a typical
range between ∼950 ppm (5th percentile) and ∼22700ppm (95th
percentile), with a median of ∼5600ppm. We found typically higher
amplitudes for shorter periods and lower effective temperatures, with
an excess of low-amplitude stars above ∼5400K.

Note (1): Derived from Teff using the isochrones of Baraffe et al. (1998,
Cat. J/A+A/337/403).
Note (2): In table 2, targets without a w value were rejected at selection
process stage 1 because the period detection did not occur in enough
segments (see Appendix A for details). In these cases, Prot, e_Prot,
LPH and w are left blank.
Note (3): References as follows:
1 = Teff and log(g) are from Dressing & Charbonneau 2013ApJ...767...95D 2013ApJ...767...95D;
0 = Teff and log(g) are from the KIC (Cat. V/133).
Note (4): Techniques required to detect a period (details in Appendices A+B):
BQR = Fault correction;
SM1 = soft smoothing;
SM2 = hard smoothing.
