Abstract

Modern transient surveys now routinely discover flares resulting from tidal disruption events (TDEs) which occur when stars, typically ∼0.5-2 M_⊙, are ripped apart after passing too close to a supermassive black hole. We present three examples of a new class of extreme nuclear transients (ENTs) that we interpret as the tidal disruption of intermediate mass (∼3-10 M_⊙) stars. Each is coincident with their host-galaxy nucleus and exhibits a smooth (<10 (2-7×10^45 erg s^-1), and long-lived (>150 days) flare. ENTs are extremely rare (≥1×10^-3 Gpc^-1 yr^-1) compared to any other known class of transients. They are at least twice as energetic (0.5-2.5× 10^53 erg) as any other known transient and these extreme energetics rule out stellar origins.

【要点】：本研究发现并解释了一种新型极端核瞬变现象，认为是由中等质量恒星被超大质量黑洞潮汐破坏所致，这些极端核瞬变现象具有更高的能量和稀有性。

【方法】：通过现代瞬变观测调查，分析了与宿主星系核相符的三例极端核瞬变事件的光变曲线和能量特征。

【实验】：研究使用了现有的观测数据，具体数据集未在摘要中提及，但分析结果指出这些极端核瞬变事件的能量是其他已知瞬变的至少两倍，持续时间超过150天，且发生频率极低（≥1×10^-3 Gpc^-1 yr^-1）。
