Deskripsi
A total of 1,018 observations (509 in B, 509 in V) of the eclipsing binary VW Cep was made during 7 nights from April through May in 1999 at Sobaeksan Optical Astronomy Observatory, using the CCD camera attached to the 61cm telescope. A time of minimum light of HJD2451327.2282 was determined from our data, and we constructed BV light curves with the data. Using, Wilson-Devinney’s binary model, we analized the light curves. The absolute dimension of M1=0.95M⨀, M2=033M⨀, R1=1.02 R⨀, R2=0.66 R⨀ of the VW Cep system were derived from our light curve solution and Kaszas et al. (1998) spectroscopic results.
