论文摘要
在本文中，我们研究了最具发光的超新星Asassn-15LH的能源源模型。我们重新访问带有完整伽马射线/X射线捕获的CSI和CSI Plus Magnet旋转的弹射循环（CSM）相互作用（CSM）相互作用（CSM）模型，这些模型由\ cite {Chatzopoulos16}采用，并发现两种型号无法适合ASASSN-15LH的侧载LC。因此，我们考虑具有具有伽马射线/X射线泄漏效果的CSI加上磁体模型，以消除理论LC的晚期过度。我们发现，该修订的模型可以再现Asassn-15LH的侧液压LC。此外，我们构建了一个新的混合模型（即CSI Plus后备模型），并发现它还可以重现Asassn-15LH的侧lomemementlomemetric LC。假设转换效率（$η$）的后备积聚到流出通常为$ \ sim10^{ - 3} $，我们得出的总质量积分为$ \ sim3.9〜m_ \ odot $。这两个模型中推断的CSM质量相当大，表明祖细胞可能会经历贫基贫困材料的喷发，然后发生了充满活力的核心折叠爆炸，留下了磁铁或黑洞。
In this paper, we investigate the energy-source models for the most luminous supernova ASASSN-15lh. We revisit the ejecta-circumstellar medium (CSM) interaction (CSI) model and the CSI plus magnetar spin-down with full gamma-ray/X-ray trapping which were adopted by \cite{Chatzopoulos16} and find that the two models cannot fit the bolometric LC of ASASSN-15lh. Therefore, we consider a CSI plus magnetar model with the gamma-rays/X-rays leakage effect to eliminate the late-time excess of the theoretical LC. We find that this revised model can reproduce the bolometric LC of ASASSN-15lh. Moreover, we construct a new hybrid model (i.e., the CSI plus fallback model), and find that it can also reproduce the bolometric LC of ASASSN-15lh. Assuming that the conversion efficiency ($η$) of fallback accretion to the outflow is typically $\sim10^{-3}$, we derive that the total mass accreted is $\sim3.9~M_\odot$. The inferred CSM mass in the two models is rather large, indicating that the progenitor could have experienced an eruption of hydrogen-poor materials followed by an energetic core-collapse explosion leaving behind a magnetar or a black hole.
