论文摘要
光学/紫外线潮汐破坏事件（TDE）的发现令人惊讶。期望是，在返回周围的人后，恒星杂交流将形成一个紧凑的磁盘，将发出软X射线。实际上，第一个TDE是在这个能量频段中发现的。光学/紫外线事件的一个常见解释是，围绕光学厚的物质重新处理了磁盘的X射线发射，并从大型Photosphere发出。如果积聚遵循超级 - 埃德丁顿的质量中心率，则不可避免地会导致充满活力的流出，从而自然而然地提供了后处理问题。我们在这里描述了一种新的方法，使用观察到的光度和温度，光学瞬变流出的质量和能量。将此方法应用于超新星样品时，我们的估计值与更详细的流体动力建模一致。对于目前的几十个光学TDE的样本，观察到的光度和温度意味着流出的流出比典型的恒星质量明显高得多，这给这一常见的后处理图片带来了问题。
The discovery of optical/UV tidal disruption events (TDEs) was surprising. The expectation was that, upon returning to the pericenter, the stellar-debris stream will form a compact disk that will emit soft X-rays. Indeed the first TDEs were discovered in this energy band. A common explanation for the optical/UV events is that surrounding optically-thick matter reprocesses the disk's X-ray emission and emits it from a large photosphere. If accretion follows the super-Eddington mass infall rate it would inevitably result in an energetic outflow, providing naturally the reprocessing matter. We describe here a new method to estimate, using the observed luminosity and temperature, the mass and energy of outflows from optical transients. When applying this method to a sample of supernovae our estimates are consistent with a more detailed hydrodynamic modeling. For the current sample of a few dozen optical TDEs the observed luminosity and temperature imply outflows that are significantly more massive than typical stellar masses, posing a problem to this common reprocessing picture.
