摘要:

本文介绍了矮新星V1040 Cen的光度测量结果。光变曲线显示了两次正常的爆发,重现时间约为40天,振幅约为2.5兆。平静数据显示了周期在0.1天(2.4小时)至0.5天(12小时)范围内的振荡,原因不明。我们测得V1040 Cen的轨道周期为P_orb = 0.060458(80)天(1.451 +-0.002 h)。根据M_v-P_orb关系,我们求得V_(1040)Cen的距离为137 ± 31 pc。本文还报道了在监测到的矮新星场中发现的11颗新的变星。

英文摘要:

We present the results of a photometric campaign of the dwarf nova V1040 Cen. The light curve shows two normal outbursts with recurrence time ~ 40 days and amplitude ~ 2.5 mag. Quiescence data show oscillations with periods in the range ~ 0.1 days (2.4 h) to ~ 0.5 days (12 h) of unknown origin. We measured the orbital period of V1040 Cen to be P_orb=0.060458(80) days (1.451+-0.002 h). Based on the M_v-P_orb relation we found the distance of V1040 Cen to be 137+-31 pc. In this paper we also report the detection of eleven new variable stars in the field of the monitored dwarf nova.
