摘要
本文作者于1989年3月27日晚及4月2日晚对PG0818+513进行了时间分辨率为63秒的高速CCD测光,得到两条完整周期的光变曲线,证明了它是激变食双星系统,轨道周期为0(?)1559.
PG 0818+513 was observed on 27 March and 2 April of 1989 with the BAO CCD Light Curve Survey photometer system. From the light curves obtained, We conclude that PG 0818+513 is a cataclysmic eclipsing binary system with an orbital period of 0~d.1559±0.0001.
