海报摘要

GSC 05586-00371 is a fast-rotating (P.rot ≈ 0.44 days) eclipsing binary. Our study showed that this star system is an overcontact eclipsing binary star that belongs to the W UMa class with characteristics of RS CVn type stars. We studied this binary system through photometric means to obtain a more precise orbital period. We also monitored the binary system to detect possible flares from the system, where two consecutive events were monitored from one of our observing stations. We have derived a model for this binary system based on the empirical data we acquired that revealed the presence of star spots on both components that evolve over a seasonal periods.
