Abstract:
Kepler ultra-high precision photometry of long and continuous
observations provides a unique dataset in which surface rotation and
variability can be studied for thousands of stars. Because many of
these old field stars also have independently measured asteroseismic
ages, measurements of rotation and activity are particularly
interesting in the context of age-rotation-activity relations. In
particular, age-rotation relations generally lack good calibrators at
old ages, a problem that this Kepler sample of old-field stars is
uniquely suited to address. We study the surface rotation and
photometric magnetic activity of a subset of 540 solar-like stars on
the main-sequence and the subgiant branch for which stellar pulsations
have been measured.
Description:
We used data collected by the NASA planet-hunter mission Kepler.
