论文摘要
我建议，最近观察到的热盘细长结构可能吞噬了Supernova（SN）1987a的中子恒星（NS）残留物，由喷气式飞机塑造，NS在获得其出生的踢速度后不久就发射了。我将两个踢后喷头的轴沿热盘伸长结构的长度延伸，我将其称为双极叶。抖动的爆炸机制解释了踢球后轴轴和射流的主轴的错位。为了使踢后的喷气机塑造双极叶，它们的能量应该等于射流内部的能量，而Ejecta内部到叶的外边缘，E（2J）〜E（EJ，Lobe）〜4.6e48erg。为0.01-0.1的效率将积聚能量转换为踢后喷射能的能量I估计，后踢后质量为MACC 〜0.0002-0.002mo。负喷气机反馈机制，喷气机消除了可能被积聚的一些质量，占积聚质量有限的质量。这项研究增加了对喷气机在核心塌陷超新星中的重要性的认识，包括爆炸后喷气机。
I suggest that the recently observed hot-dust elongated structure that likely engulfs the neutron star (NS) remnant of supernova (SN) 1987A was shaped by jets that the NS launched shortly after it acquired its natal kick velocity. I take the axis of the two post-kick jets to be along the long dimension of the hot-dust elongated structure, which I term the bipolar lobe. The jittering jets explosion mechanism accounts for the misalignment of the post-kick jets axis and the main-jets axis of the ejecta. For post-kick jets to shape the bipolar lobe their energy should have been about equal to the energy of the ejecta inner to the outer edge of the lobe, E(2j)~E(ej,lobe)~4.6e48erg. For an efficiency of 0.01-0.1 to convert accretion energy to post-kick jets' energy I estimate that the post-kick accreted mass was Macc~0.0002-0.002Mo. The negative jets feedback mechanism, where jets remove some of the mass that could have been accreted, accounts for the limited amount of accreted mass. This study adds to the growing recognition of the importance of jets in core collapse supernovae, including post-explosion jets.
