Abstract:
The analysis of non-variable stars is generally neglected in the
literature. However, such objects are needed for many calibration
processes and for testing pulsational models. The photometric time
series of the Kepler satellite mission still stand as the most
accurate data available today and are excellently suited to the search
for non-variable stars. We analysed all long-cadence light curves for
stars not reported as a variable so far from the Kepler satellite
mission. Using the known characteristics and flaws of these data sets,
we defined three different frequency ranges where we searched for
non-variability. The found non-variable objects are mostly cooler than
the 7000K populating the whole main sequence (MS) to the red giant
branch (RGB).
Description:
We used the Lomb-Scargle periodogram and the false-alarm probability
(FAP) to analyse the cleaned data sets of 138451 light curves. We
then used log FAP≥-2 to define a star as "non-variable" in the ranges
below 0.1c/d, 0.1 to 2.0c/d, and 2.0 to 25.0c/d, respectively.
Furthermore, we also calculated the standard deviation of the mean
light curve to obtain another parameter. Here we present the
parameters of all apparent non-variable stars
