| 英文摘要 | In this paper, the first complete photometric light curves in the B, V, and R passbands for an eclipsing binary LO Com are presented, and the photometric solution for the LO Com is derived by analyzing these light curves by using the Wilson and Devinney code. From the photometric solution, it is found that the LO Com is a W-type W UMa binary with a mass ratio ofq=m(2)/m(1)=2.478 and a contact degree of f=(3.2 +/- 0.25)%. By combining the two new minimum times with those published earlier in the literature, we have found that the (O - C) curve shows a downward parabolic variation corresponding to a long-term decrease in the orbital period with a rate of dP dt=-1.18 x 10(-7) days yr(-1). This long-term decrease in its orbital period may be caused by mass transfer from the more massive component to the less massive one. |
