| 英文摘要 | The CCD photometric data of an EW-type binary, II CMa, which is a contact star in the field of the middle-aged open cluster Berkeley 33, are presented. A complete R light curve was obtained. In the present work, using the five CCD epochs of light minimum [three of them were calculated from Mazur et al. (1993 MNRAS, 265, 405)'s data and two from our new data], the orbital period P was revised to 0.22919704 days. The complete R light curve was analyzed by using the 2003 version of W-D (Wilson-Devinney) program. It is found that this is a contact system with a mass ratio of q = 0.9 and a contact factor of f = 4.1%. The high mass ratio (q = 0.9) and the low contact factor (f = 4.1%) indicate that the system just evolved into the marginal contact stage. |
