VizieR Online Data Catalog: Kepler stars' surface differential rotation (de Freitas, 2019)

The Kepler mission performed 17 observational runs for ~90d each, and these runs, designated as Quarters, were composed of long-cadence (data sampling every 29.4min) and short-cadence (sampling every 59s) observations.

Based on a working sample adopted by Reinhold et al. (2013A&A...560A...4R, Cat. J/A+A/560/A4) with well-determined rotation periods, we constructed our light curves using only Quarter 3 long-cadence data. All time series have been normalized to the median value of Q3. Our final working sample consisted of 662 active stars with physical properties similar to those of the Sun, defined by T_eff between 5579 and 5979K, logg between 3.94 and 4.94dex (Pinsonneault et al. 2012ApJS..199...30P, Cat. J/ApJS/199/30) and (primary) rotation periods between 24 and 34d.

Among the total of 662 stars, 141 were detected to have DR traces, while the rest were identified as having rigid-body rotation. The period interval for the above-mentioned selection was based on the results from Lanza et al. (2003A&A...403.1135L), for which the rotational periods of the Sun are between 24.5d (equator) and 33.5d (poles). Values for the rotational periods were estimated using an autocorrelation function and were taken from Reinhold et al. (2013A&A...560A...4R, Cat. J/A+A/560/A4), and the temperature and gravity were obtained from Pinsonneault et al. (2012ApJS..199...30P, Cat. J/ApJS/199/30); that is, the corrected Sloan Digital Sky Survey (SDSS) temperature and the Kepler Input Catalogue (KIC) surface gravity.
