论文摘要
我估计了中微子加热增加的能量，从而在核心倒塌超新星（CCSNE）中诱导的流出量诱导的流出，并发现这种能量使喷气机沉积到外部核心的能量翻了一番。我认为抖动的喷气机爆炸机制，那里有几个随机的喷射发作，每个发动机持续约0.01-0.1秒。塌陷的核心物质通过约100 km的停滞冲击，然后缓慢流入原始恒星（NS）。我认为Proto-NS发射了抖动的喷气机，并且喷气机从停滞的冲击中爆发出来。我检查了促进过程，在该过程中，停滞的冲击（增益区域材料）内的高压气体与喷气机一起扩展，并确实在喷气机休克（Jets Shock）（Cocoon）的材料上工作。这项工作与原始喷气机携带的能量粗略地等于。我认为，不稳定性，随机旋转，磁场和抖动喷气机之间的耦合导致大多数CCSN爆炸。在其他情况下，爆发前的核心正在迅速旋转，因此有序旋转代替随机旋转，固定喷气机取代了抖动的喷气机。
I estimate the energy that neutrino heating adds to the outflow that jets induce in the collapsing core material in core collapse supernovae (CCSNe), and find that this energy crudely doubles the energy that the jets deposit into the outer core. I consider the jittering jets explosion mechanism where there are several stochastic jet-launching episodes, each lasting for about 0.01-0.1 seconds. The collapsing core material passes through the stalled shock at about 100 km and then slowly flows onto the proto-neutron star (NS). I assume that the proto-NS launches jittering jets, and that the jets break out from the stalled shock. I examine the boosting process by which the high-pressure gas inside the stalled shock, the gain region material, expands alongside the jets and does work on the material that the jets shock, the cocoon. This work is crudely equal to the energy that the original jets carry. I argue that the coupling between instabilities, stochastic rotation, magnetic fields, and jittering jets lead to most CCSN explosions. In other cases, the pre-collapse core is rapidly rotating and therefore ordered rotation replaces stochastic rotation and fixed jets replace jittering jets.
