Rotational modulation of the brightness and the spotted regions of the red dwarfs DK Leo, AD Leo, and GT Peg
The rotational modulation and variability of the mean brightness ofthree poorly studied spotted red dwarfs are considered. Theirphotometric behavior can be described well by a zonal spottedness model.The areas of the spots comprise up to 11-13% of the total stellarsurface, and the spots themselves are 600-1500 K cooler than thesurrounding photosphere.
