Photoelectric observations of the flare star BD + 55° 1823
Abstract
A light variation in Johnson'sV-band of flare star EV Lac has been registered by Pettersen (1980). The cycle length was 4{./d}378 with amplitude about 0{./m}07. A Fourier analysis programme has been applied on our measured data of the flare star BD+55°1823 in Johnson'sV andB bands. A period of 16d and amplitude of 0{./m}14 have been detected in theV-band.
