W Uma Type Eclipsing Binary Vw Cep

Scientific paper

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 = 0.95Msolar, M2 = 0.33Msolar, R1 = 1.02Rsolar, R2 = 0.66Rsolar of the VW Cep system were derived from our light curve solution and Kaszas et al. (1998) spectroscoppic rsult.
