关于喷流在相互作用双星中作用的两次会议综述
A summary of two meetings on the role of jets in interacting stellar binaries
摘要：
在2017年7月关于恒星双星系统的两次会议上，我总结了我的观点，即在大多数强相互作用的恒星双星系统中，喷流起着决定性的作用。在The Physics of Evolved Stars II：The role of Binarity（尼斯，2017年7月10日至13日）会议上，许多演讲和海报都集中在星周物质的塑造上，并取得了一些重要的新成果，比如对双星系统发射的宽喷流的观测。在双星对恒星演化的影响会议（ESO Garching，2017年7月3日至7日）中，无论是在开幕式还是总结演讲中，发言者都提到“教科书最有可能需要重写”。我指出，有些新的章节已经写好了，尽管研究人员并不阅读它们，而是继续参考“旧教科书”。例如，太多的演讲者和作者一直只提到Ia超新星的祖先的单简并和双简并情况。研究人员还必须参考关于核心简并（CD）情景的“新教科书章节”。其他的例子涉及喷射的作用。喷流导致了一个新的进化阶段，即掠食包络进化（GEE），这应该与旧的进化阶段一起考虑，例如，共同的包络演变，洛希瓣溢出（RLOF），风的质量损失和吸积。我讨论如何GEE可以解决一些令人费解的二元系统。我们还应该考虑喷流作为额外能量源的作用，以消除共同的包络，并为中等亮度的光学瞬变提供动力。射流的一个强大优势是，在许多情况下，它们通过负反馈机制运行，因此不需要微调。喷流反馈机制（JFM）的运作也将双星演化与大质量恒星的爆炸（核心坍缩超新星）联系起来。
英文摘要：
In relation to two meetings on stellar binary systems in July 2017, I summarize my view that in the majority of strongly interacting stellar binary systems jets play decisive roles. In the meeting The Physics of Evolved Stars II: The role of Binarity (Nice, July 10-13, 2017) many talks and posters were concentrated on the shaping of circumstellar matter, with some significant new results, like the observations of wide jets launched from binary systems. In the meeting The Impact of Binaries on Stellar Evolution (ESO Garching, July 3-7, 2017), both in the opening and the summary talks the speakers mentioned that "Textbooks need most likely to be rewritten". I made my point that some new chapters were already written, although researchers do not read them but rather keep referring to the `old textbooks'. For example, too many speakers and authors keep referring only to the single degenerate and double degenerate scenarios for the progenitors of SNe Ia. Researchers must refer also to the `new textbook chapter' on the core degenerate (CD) scenario. Other examples involve the role of jets. Jets lead to a new evolutionary phase, that of the grazing envelope evolution (GEE), that should be considered alongside the older ones, e.g., the common envelope evolution, Roche lobe overflow (RLOF), and wind mass loss and accretion. I discuss how the GEE can solve some puzzling binary systems. We should also consider the role of jets as an extra energy source to remove the common envelope and in powering intermediate luminosity optical transients (ILOTs). One strong advantage of jets is that in many cases they operate through a negative feedback mechanism, hence preventing the need for a fine tuning. The operation of the jet feedback mechanism (JFM) connects also binary evolution to explosion of massive stars as core collapse supernovae.
