A photometric study of V608 Cam: apparent period changes as a result of surface activity
Original language description
The VRI light curves were measured for the low-mass eclipsing binary V608 Cam as a part of our long-term observational project for studying of eclipsing binaries with a short orbital period. The TESS light curve solution in PHOEBE results to the detached configuration, where the temperature of the primary component was fixed to T1 = 5300 K according to GAIA results, which gives us T2 = 4110 +/- 50 K for the secondary. The spectral type of the primary component was derived to be K0 and the photometric mass ratio was estimated q = 0.92 +/- 0.07. Characteristics and temporal variation of the dark region on the surface of the secondary component were estimated and are attributed to apparent period changes of this eclipsing binary with a cycle of about 2.4 yr.
