Abstract (from CDS):

Our time series analysis of sixteen BV light curves of the chromospherically active binary V511 Lyr confirmed the 2.7d rotation period uniquely. The seasonal periodicity changes of 3.8% indicated the presence of detectable surface differential rotation. The significant 2.67455d periodicity in the light curve minimum epochs suggested that the strongest starspot formation in V511 Lyr was concentrated on one stable active longitude.
