论文摘要
共同的包膜阶段首先提出了四十多年前，以解释诸如灾难变量之类的进化，紧密的二进制文件的起源。现在，人们认为该阶段在从IA型超新星到二进制黑洞的各种其他现象的形成中起着至关重要的作用，而共同的包膜合并可能是导致一系列神秘的瞬变和超新星冒名顶替者的原因。然而，尽管其重要性显而易见，但共同的信封阶段仍然鲜为人知。在这里，我们概述了涉及的一些基本原则，其余的问题以及最近的一些观察性暗示（即行星星云和发光的红色Novae），这可能会导致这些开放的问题。
The common envelope phase was first proposed more than forty years ago to explain the origins of evolved, close binaries like cataclysmic variables. It is now believed that the phase plays a critical role in the formation of a wide variety of other phenomena ranging from type Ia supernovae through to binary black holes, while common envelope mergers are likely responsible for a range of enigmatic transients and supernova imposters. Yet, despite its clear importance, the common envelope phase is still rather poorly understood. Here, we outline some of the basic principles involved, the remaining questions as well as some of the recent observational hints from common envelope phenomena - namely planetary nebulae and luminous red novae - which may lead to answering these open questions.
