论文摘要
我们对弱喷气机进行了三维流体动力学模拟，这些模拟在爆炸后半小时发射到核心崩溃的超新星（CCSNE）弹出器中，发现快速喷气机与CCSN弹射器的相互作用与CCSN射流产生的高压区域会引起高压回流，从而引起大量增生的新生中性中子星星。在较弱的喷气机的情况下，总功率为10^45-10^46 ERG，回流质量积聚可能会为更耗时的喷气机提供动力。总的来说，两次爆炸后喷射发射发作的喷射具有足够的能量来影响内部喷射的形态，质量为0.1 m_o。我们的结果表明，在某些（可能是少数）CCSN残留物中，内部区域可能会显示出由探索后弱喷头引起的双极结构。这部分之外的区域可能会显示出抖动喷气机的形态。
We conduct three-dimensional hydrodynamical simulations of weak jets that we launch into a core collapse supernovae (CCSNe) ejecta half an hour after the explosion and find that the interaction of the fast jets with the CCSN ejecta creates high pressure zones that induce a backflow that results in mass accretion onto the newly born neutron star. In cases of weak jets, a total power of 10^45-10^46 erg, the backflow mass accretion might power up to an order of magnitude more energetic jets. In total, the jets of the two post-explosion jet-launching episodes have enough energy to influence the morphology of the very inner ejecta, a mass of 0.1 M_O. Our results imply that in some, probably a minority of, CCSN remnants the very inner regions might display a bipolar structure that results from post-explosion weak jets. The regions outside this part might display the morphology of jittering jets.
