| 摘 要： | BB Peg和BX Peg是两个WUMa型的短周期食双星。1978年10—11月间,我们用60厘米反射望远镜对它们进行了宽波段黄、蓝两色光电观测,并作了常规的消光归化工作,取得B、V观测结果。在所得光变曲线的食相内,两星均有一段平底的相区,表明它们是全食类型的密近双星。正在试用中的高速光度计对其极小时刻观测的结果,也证实了这一新情况。高

| Abstract: | BV photoelectric photometry of the two W UMa-type systems, BB Peg and BX Peg was carried out from October to November, 1978. In both cases conventional light curves and high-speed photometry of the minima revealed the binaries' total eclipse features. New-period values and new-light elements have been determined. From statistical analyses of the "0-C" diagram it was found tha the period of BB Peg showed no obvious long-term variations in the past 40-odd years. |
