论文摘要
我们模拟主序列对剥离的eNVELOPE(IB型或IC)核心倒塌超新星(CCSN)的爆炸的响应,当主序列恒星在爆炸时10-20RO的核心绕芯绕核心旋转。我们使用恒星进化代码台面遵循质量3MO和7MO对能量沉积和质量去除的主要序列星的响应。 CCSN喷射与主序列星的碰撞使能量沉积并膨胀主序列星。如果二进制系统在CCSN爆炸后保持束缚,则膨胀的主序列可能会吞噬新出生的中子星(NS)。我们假设NS通过积聚磁盘积聚质量并发射喷气机。喷气机从膨胀的主序列恒星中取出质量,并与CCSN喷射碰撞。尽管这种情况很少见,但它加起来与其他罕见情况相比,进一步支持了许多被剥离的信封CCSNE由后期喷气机提供动力的观念。已故的喷气机可以长时间为这些CCSNE-I提供动力,并可能在其轻弯曲中撞击。喷气机还可能将内部喷射塑造成双极形态。我们的结果进一步支持建议,即有几种方法可以喂养NS(或黑洞)以在超浮肿的超新星中发射晚喷射。
We simulate the response of a main sequence star to the explosion of a stripped-envelope (type Ib or Ic) core collapse supernova (CCSN) when the main sequence star orbits the core at a distance of 10-20Ro at explosion. We use the stellar evolution code MESA to follow the response of main sequence stars of masses 3Mo and 7Mo to energy deposition and mass removal. The collision of the CCSN ejecta with the main sequence star deposits energy and inflate the main sequence star. If the binary system stays bound after the CCSN explosion the inflated main sequence star might engulf the newly born neutron star (NS). We assume that the NS accretes mass through an accretion disk and launches jets. The jets remove mass from the inflated main sequence star and collide with the CCSN ejecta. Although this scenario is rare, it adds up to other rare scenarios to further support the notion that many stripped envelope CCSNe are powered by late jets. The late jets can power these CCSNe-I for a long time and might power bumps in their lightcurve. The jets might also shape the inner ejecta to a bipolar morphology. Our results further support suggestions that there are several ways to feed a NS (or a black hole) to launch the late jets in superluminous supernovae.
