FUor和类FUor天体的光学光变曲线

Optical light curves of FUor and FUor-like objects

E. Semkov, S. Peneva, S. Ibryamov

摘要:

利用最近的光度监测数据和照相底片档案的数据,我们的目标是研究FUors的长期光度行为。FUOR历史光变曲线的构建对于确定爆发的开始、达到最大光的时间、亮度的增加和减少的速率、恒星爆发前的变化是非常重要的。我们的CCD测光观测是用罗真(保加利亚)和Skinakas(希腊克里特岛)天文台的望远镜进行的。最适合长期测光研究的是大型施密特望远镜的底片档案,如木曾天文台、阿西亚戈天文台、帕洛玛天文台等的望远镜。在比较我们的结果与光变曲线的研究FUor,我们得出结论,每一个新的FUor对象表现出不同的光度行为。每个已知的FUor具有不同的亮度增加和减少速率以及不同的光曲线形状。

英文摘要:

Using recent data from photometric monitoring and data from the photographic plate archives we aim to study, the long-term photometric behavior of FUors. The construction of the historical light curves of FUors could be very important for determining the beginning of the outburst, the time to reach the maximum light, the rate of increase and decrease in brightness, the pre-outburst variability of the star. Our CCD photometric observations were performed with the telescopes of the Rozhen (Bulgaria) and Skinakas (Crete, Greece) observatories. Most suitable for long-term photometric study are the plate archives of the big Schmidt telescopes, as the telescopes at Kiso Observatory, Asiago Observatory, Palomar Observatory and others. In comparing our results with light curves of the well-studied FUors, we conclude that every new FUor object shows different photometric behavior. Each known FUor has a different rate of increase and decrease in brightness and a different light curve shape.
