What makes a supernova truly “peculiar?” In this review we attempt to address this question by tracing the history of the use of “peculiar” as a descriptor of non-standard supernovae back to the original binary spectroscopic classification of Type I vs. Type II proposed by Minkowski (Publ. Astron. Soc. Pac., 53:224, 1941). A handful of noteworthy examples are highlighted to illustrate a general theme: classes of supernovae that were once thought to be peculiar are later seen as logical branches of standard events. This is not always the case, however, and we discuss ASASSN-15lh as an example of a transient with an origin that remains contentious. We remark on how late-time observations at all wavelengths (radio-through-X-ray) that probe 1) the kinematic and chemical properties of the supernova ejecta and 2) the progenitor star system’s mass loss in the terminal phases preceding the explosion, have often been critical in understanding the nature of seemingly unusual events.

奇特的超新星

是什么让超新星真正“与众不同”?在这篇综述中,我们试图通过追溯使用“特殊”作为非标准超新星描述符的历史回到 Minkowski (Publ. Astron. Soc. Pac., 53:224, 1941)。突出显示了一些值得注意的例子来说明一个普遍的主题:曾经被认为是奇特的超新星类别后来被视为标准事件的逻辑分支。然而,情况并非总是如此,我们将 ASASSN-15lh 作为一个瞬变的例子进行讨论,该瞬变的起源仍然存在争议。
