The alteration of total star brightness can be caused by individual spots, hence the variations of stars light curves can be used to detect the spots in the star. Moreover, the sizes of spots can be deduced from the planetary transit light curves via short-cadence measurements. In this study, we are going to examine the short-cadence (~1 min) planetary transit light curves of 38 stars with effective temperature ranging from 3948 K to 8848 K as identified in Mueller et al. (A&A, 560, A123, 2013). And, show that curves can be used to generate the star spot data sets of individual stars. This analysis will allow us to examine the time variations and size distributions of the star spots of individual stars.
