摘要
20 0 0年 3月 7日至 11日 ,用北京天文台兴隆观测站的 60cm望远镜 ,对窄线赛弗特Ⅰ型星系 (NLS1)PG12 4 4 +0 2 6,IRAS1334 9+2 4 38,MARK142 ,MARK766进行了R波段的多次观测 .作为参照样本 ,还观测了Blazar天体S50 716+71,S50 836+71,S50 954+65,S4 174 9+70和赛弗特Ⅰ型星系MARK10 6,NGC30 80 ,MARK634 .观测结果表明 :所观测的NLS1和赛弗特Ⅰ型星系大都不存在明显的短时标光变 ,只有NLS1PG12 4 4 +0 2 6和赛弗特Ⅰ型星系MARK634可能存在短时标变化的事件 .
Narrow line Seyfert 1s: PG1244+026, IRAS13349+2438, MARK142, MARK766 have been observed with the 60 cm telescope at Xinglong station fo Beijing Astronomy Observatory from 2000 03 07—11. The observation has been done at R bond with several times during a night. As a comparable sample, the Blazar Object: S5 0716+71, S5 0836+71, S5 0954+65, S4 1749+70; and Seyfert 1 galaxies: MARK106, NGC3080, MARK 634 also have been observed. The results of the observation suggest that all the narrow line Seyfert 1s and Seyfert 1 galaxies which have been observed by us don't present optical rapid variability, only two possible events in the narrow line Seyfert 1s PG1244+026 and Seyfert 1 galaxies MARK634 should be presented rapid variability at optical bond. And all the Blazar objects have been found remarkable optical rapid variability.
