摘要: Continuous photometric observations of the visible component single-line, K2IV spectroscopic binary II Peg carried out by MOST satellite during 31 consecutive days in 2008 have been analyzed. On top spot-induced brightness modulation, eleven flares were detected three distinct types characterized different values rise, decay and duration times. The showed a preference for occurrence at rotation phases when most spotted hemisphere is directed to observer, confirming previous similar reports. An attempt detect grazing primary minimum caused secondary transiting front star gave negative result. variability spots has interpreted within cold spot model. assumption differential better fit light curve than solid-body
