FU或PGIR20dci的历史性Ks光变曲线

The historic Ks light curve of the FUor PGIR20dci

Klaus W. Hodapp, Scott E. Dahm, Watson P. Varricatt

摘要:

我们报告了Hillenbrand等人(2021)最近发现的FU或PGIR20dci的历史性KS波段光变曲线。我们发现在FUor爆发之前,该物体存在一些微小的变化,亮度最初上升相当缓慢,随后在2019年急剧上升到最大值。

英文摘要:

We report a historic Ks-band light curve spanning over three decades of the FUor PGIR20dci recently discovered by Hillenbrand et al. (2021) . We find some minor variability of the object prior to the FUor outburst, an initial rather slow rise in brightness, followed in 2019 by a much steeper rise to the maximum.
