摘要
本文给出射电宁静类星体PHL 938在20多年内的光度观测资料,结果表明其亮度具有小振幅的长期变化趋势,其中带有短期的偏移。并得到PHL 938的发射区的大小为0.32pc。
Photometric data for the radio-quiet quasar PHL 938 have been obtained over a period of more than 20 years. The data and light curve are presented. The results show that the brightness of this radio-quiet and absorption-line quasar has a long-term trend of variation of small amplitude with short-term deviations. The size of the emitting region of PHL 938 is 0.32 pc.
