摘要

潮汐破坏事件(TDE)发生在超大质量黑洞潮汐破坏附近经过的恒星时。被破坏的恒星的后退吸积速率可能超过爱丁顿极限，这会导致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，并且对这类事件的观测数量正在迅速增加。在本文中，我们用一种新的公共的、面向对象的代码TiDE来拟合20条TDE光曲线。我们将我们的结果与流行的MOSFiT和最近开发的TDEmass代码得到的结果进行了比较，并讨论了可能的差异来源。

Fitting Optical Light Curves of Tidal Disruption Events with TiDE

Abstract 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.

期刊介绍： The Publications of the Astronomical Society of the Pacific (PASP), the technical journal of the Astronomical Society of the Pacific (ASP), has been published regularly since 1889, and is an integral part of the ASP''s mission to advance the science of astronomy and disseminate astronomical information. The journal provides an outlet for astronomical results of a scientific nature and serves to keep readers in touch with current astronomical research. It contains refereed research and instrumentation articles, invited and contributed reviews, tutorials, and dissertation summaries.
