Abstract:
We analyzed the host stars of the present sample of confirmed planets
detected by Kepler and Kepler Objects of Interest to compute new
photometric rotation periods and to study the behavior of their
angular momentum. Lomb-Scargle periodograms and wavelet maps were
computed for 3807 stars. For 540 of these stars, we were able to
detect rotational modulation of the light curves at a significance
level of greater than 99%. For 63 of these 540 stars, no rotation
measurements were previously available in the literature. According to
the published masses and evolutionary tracks of the stars in this
sample, the sample is composed of M- to F-type stars (with masses of
0.48-1.53M☉) with rotation periods that span a range of
2-89 days. These periods exhibit an excellent agreement with those
previously reported (for the stars for which such values are
available), and the observed rotational period distribution strongly
agrees with theoretical predictions. Furthermore, for the 540 sources
considered here, the stellar angular momentum provides an important
test of Kraft's relation based on the photometric rotation periods.
Finally, this study directly contributes in a direct approach to our
understanding of how angular momentum is distributed between the host
star and its (detected) planetary system; the role of angular momentum
exchange in such systems is an unavoidable piece of the stellar
rotation puzzle.
Description:
We selected all public LCs available in the Kepler Public Archive for
planet-hosting stars and KOIs between quarters 1 and 17, which were
collected over the noted range of four years (from 2009 May 13 to 2013
May 08). From this parent sample, 408 Kepler Confirmed Planetary Host
Stars (hereafter KCP) were available in the Kepler Public Archive.
