论文摘要

我回顾了对核心崩溃超新星(CCSNE)和类似的瞬态事件的研究,这些事件将主要作用归因于喷气机在为大多数CCSNE和塑造其喷射的动力方面。我首先要审查我为大多数CCSN爆炸供电的抖动爆炸机制。中微子加热确实在增强喷气机方面发挥了作用。我将某些CCSN残留物的形态与行星星云进行了比较,以结论喷气机和不稳定性是其喷射的塑造背后的。然后,我讨论CCSNE是快速旋转崩溃的后代,导致固定轴喷射(带有小抖动)形成双极射流。一小部分双极CCSNE是超小超新星(SLSNE)。我得出的结论是,即使在考虑到能量磁铁和/或弹出式相互作用时,Lightcurves中Slsne Lightcurves和Bumps的建模也必须包括喷气机(CSM)。我将双极CCSNE的性质连接到公共包络喷射超新星(CEJSNE),其中一个旧的中子星或黑洞内的信封内螺旋式螺旋形,然后在红色超级巨人的核心内。我讨论了喷气机如何像Supernova 1987a一样塑造前爆炸性CSM,并可以在CCSNE和CEJSNE的二进制系统祖细胞中为前爆炸前爆发(前体)提供动力。二进制互动也有助于推出后爆炸喷气机。

I review studies of core collapse supernovae (CCSNe) and similar transient events that attribute major roles to jets in powering most CCSNe and in shaping their ejecta. I start with reviewing the jittering jets explosion mechanism that I take to power most CCSN explosions. Neutrino heating does play a role in boosting the jets. I compare the morphologies of some CCSN remnants to planetary nebulae to conclude that jets and instabilities are behind the shaping of their ejecta. I then discuss CCSNe that are descendants of rapidly rotating collapsing cores that result in fixed-axis jets (with small jittering) that shape bipolar ejecta. A large fraction of the bipolar CCSNe are superluminous supernovae (SLSNe). I conclude that modelling of SLSNe lightcurves and bumps in the lightcurves must include jets, even when considering energetic magnetars and/or ejecta interaction with the circumstellar matter (CSM). I connect the properties of bipolar CCSNe to common envelope jets supernovae (CEJSNe) where an old neutron star or a black hole spirals-in inside the envelope and then inside the core of a red supergiant. I discuss how jets can shape the pre-explosion CSM, as in supernova 1987A, and can power pre-explosion outbursts (precursors) in binary systems progenitors of CCSNe and CEJSNe. Binary interaction facilitate also the launching of post-explosion jets.
