| 英文摘要 | TX Cnc is a member of the young open cluster NGC 2632. In the present paper, four CCD epochs of light minimum and a complete V light curve of TX Cnc are presented. A period investigation based on all available photoelectric or CCD data showed that it is superimposed on a long-term increase (dP/dt = +3.97 x 10(-8) d yr(-1)), and weak evidence suggests that it includes a small-amplitude period oscillation (A(3) = 0.(d)0028; T-3 = 26.6 yr). The light curves in the V band obtained in 2004 were analyzed with the 2003 version of the W-D code. It was shown that TX Cue is an overcontact binary system with a degree of contact factor f = 24.8% (+/- 0.9%). The absolute parameters of the system were calculated: M-1 = 1.319 +/- 0.007 M-circle dot M-2 = 0.600 +/- 0.01 M-circle dot; R-1 = 1.28 +/- 0.19 R-circle dot, R-2 = 0.91 +/- 0.13 R-circle dot. TX Cnc may be on the TRO-controlled stage of the evolutionary scheme proposed by Qian (2001a, b, 2003a), and may contain an invisible tertiary component (m(3) approximate to 0.097 (circle dot)). If this is true, the tertiary component has played an important role in the formation and evolution of TX Cnc by removing angular momentum from the central system (Pribulla & Rucinski 2006). In this way the contact binary configuration can be formed in the shortlife time of a young open cluster via AML. |
