A photometric study of HAT 141-03513: another twin of the V361 Lyr system
Original language description
The BVRI light curves were measured for the eclipsing binary HAT 141-03513 as a part of our long-term observational project for studying low-mass eclipsing binaries with a short orbital period. The asymmetric light curve and the difference in brightness in maxima, are probably the result of presence of a hot region on the surface of one component. The light curve solution in PHOEBE results to the semidetached, nearly contact configuration, where the primary fills its Roche lobe. The temperature of primary component was fixed to T-1 = 4220 K according to GAIA results, which gives us T-2 = 3555 +/- 150 K for the secondary. The spectral type of the primary component was estimated to be K6 and the photometric mass ratio was derived q = 0.435 +/- 0.015. Characteristics of the hot region were estimated. The properties of this mass-exchanging semidetached binary are compared with two previously known similar systems, V361 Lyr and V549 Cam.
