A First Look at Differential Rotation in Kepler Open Clusters NGC 6811 (1 Gyr) and NGC 6819 (2.5 Gyr)
Abstract
Open clusters are ideal targets for controlled studies of stellar properties, since members are coeval and have the same abundances. We present the first results of measurements of surface differential rotation (SDR) in two clusters of different ages in the Kepler field. We compare results for single stars over a range of masses and rotation rates, and compare and contrast these with previous results for single and binary stars. All of these properties are found to have an effect on the average SDR rate.
