A Tidal Disruption Event (TDE) occurs when a supermassive black hole tidally disrupts a nearby passing star. The fallback accretion rate of the disrupted star may exceed the Eddington limit, which induces a supersonic outflow and a burst of luminosity, similar to an explosive event. Thus, TDEs can be detected as very luminous transients, and the number of observations for such events is increasing rapidly. In this paper we fit 20 TDE light curves with TiDE, a new public, object-oriented code designed to model optical TDE light curves. We compare our results with those obtained by the popular MOSFiT and the recently developed TDEmass codes, and discuss the possible sources of differences.

使用 TiDE 拟合潮汐破坏事件的光学光曲线


当超大质量黑洞潮汐扰乱附近经过的恒星时，就会发生潮汐扰乱事件（TDE）。破碎恒星的后退吸积率可能会超过爱丁顿极限，从而引发超音速流出和光度爆发，类似于爆炸事件。因此，TDE 可以被检测为非常明亮的瞬变，并且此类事件的观测数量正在迅速增加。在本文中，我们使用 TiDE 拟合 20 个 TDE 光曲线，TiDE 是一种新的公共面向对象代码，旨在对光学 TDE 光曲线进行建模。我们将我们的结果与流行的 MOSFiT 和最近开发的 TDEmass 代码获得的结果进行比较，并讨论可能的差异来源。
