报告摘要：

We use high accuracy photometric data obtained with the Kepler satellite to study the activity modulations of stars using a variety of techniques, including power spectrum analysis and spot modeling, in order to measure stellar differential rotation and physical characteristics of star spots. A further step can be accomplished with the “exploitation” of possible transiting companions in order to obtain critical information about the stellar surface which is occulted during the eclipses. To that end we use the unsharp masking technique of the transit residuals. The efficiency of our procedures is demonstrated with the analysis of the systems Kepler-210 and KOI-1452.
