论文摘要
我分析了发光瞬态事件SN 2019ZRK的某些特性，并得出结论认为，喷气机是爆发前爆发（前体）的主要动力来源，并且是对大量情节物质（CSM）的弹射，非常有力的爆炸本身，以及在轻曲线中的爆发后爆炸。预爆术能源主要是伴侣（主要序列，狼射线，中子星或黑洞），该恒星积聚了质量并发射了喷气机。我发现，爆炸喷射加速后CSM的快速扩展要求爆炸能量> 10^{52} ERG。只有喷气驱动的爆炸才能在这种SN 2009IP样瞬变中提供这种能量。我得出的结论是，弹出的互动极不可能在爆炸后约110天后为明亮的颠簸供电。取而代之的是，我通过应用喷气驱动的颠簸玩具模型来表明，爆炸后喷气机是颠簸的最有可能的解释。我打开一个问题，即爆炸本身（主要爆发）是核心崩溃超新星（CCSN）还是常见的信封喷气机超新星（CEJSN）。在这项研究中，我通过争辩说，从常规的CCSNE到超薄CCSNE以及许多其他特殊和超级能源的瞬态事件，包括JET驱动所有事件，将所有事件驱动到包括CEJSNE在内的所有其他事件，再加上所有事件。在分析所有这些类型的瞬变时，不能忽略喷射动力。
I analyse some properties of the luminous transient event SN 2019zrk and conclude that jets were the main powering sources of the pre-explosion outburst (precursor) and ejection of a massive circumstellar matter (CSM), of the very energetic explosion itself, and of the post-explosion bump in the light curve. The pre-explosion energy source is mainly a companion (main sequence, Wolf-Rayet, neutron star or black hole) star that accreted mass and launched jets. I find that the fast expansion of the CSM after acceleration by the explosion ejecta requires the explosion energy to be >10^{52} erg. Only jet-driven explosions can supply this energy in such SN 2009ip-like transients. I conclude that ejecta-CSM interaction is extremely unlikely to power the bright bump at about 110 days after explosion. Instead, I show by applying a jet-driven bump toy-model that post-explosion jets are the most likely explanation for the bump. I leave open the question of whether the explosion itself (main outburst) was a core collapse supernova (CCSN) or a common envelope jets supernova (CEJSN). In this study I further connect peculiar transient events, here 2009ip-like transient events, to CCSNe by arguing that jets drive all events, from regular CCSNe through superluminous CCSNe and to many other peculiar and super-energetic transient events, including CEJSNe. Jet-powering cannot be ignored when analyzing all these types of transients.
