论文摘要
我研究了IB型或类型IC（剥离的Envelope）核心倒塌超新星（CCSN）的中子星（NS；或黑洞）伴侣的案例，并在爆炸后几分钟到数小时就向爆炸喷射中增添了质量。 A = 1-5RO的前探索半径处的NS轨道。我发现，当弹射速度降低<1000-1500 km/s时，NS增生具有足够的特定角动量以形成NS周围的积聚盘。 NS通过在10分钟到几个小时的时间段内通过积聚磁盘积聚了3E-5至3E-4的弹出质量。如果喷气机含有约10％的吸积能，那么它们的总能量约为弹射器动能的0.003-0.03。这些喷气机从NS（或黑洞）伴侣到CCSN的含义是塑造内部喷射以具有双极形态，使CCSN的光曲线充满活力，在某些情况下，可能会通过R-Process元素富集内部喷射。
I study cases where a neutron star (NS; or a black hole) companion to a type Ib or type Ic (stripped-envelope) core collapse supernova (CCSN) accretes mass from the explosion ejecta and launches jets minutes to hours after explosion. The NS orbits at a pre-explosion radius of a=1-5Ro. I find that when the ejecta velocity drops to be <1000-1500km/s the ejecta gas that the NS accretes possesses sufficient specific angular momentum to form an accretion disk around the NS. The NS accretes a fraction of 3e-5 to 3e-4 of the ejecta mass through an accretion disk over a time period of 10min to few hours. If the jets carry about ten per cent of the accretion energy, then their total energy is a fraction of about 0.003-0.03 of the kinetic energy of the ejecta. The implications of these jets from a NS (or a black hole) companion to a CCSN are the shaping the inner ejecta to have a bipolar morphology, energising the light curve of the CCSN, and in some cases the possible enrichment of the inner ejecta with r-process elements.
