论文摘要

Ligo-Virgo科学合作的引力波检测表明,黑洞和中子星(BH-NS)或BH-BH系统在宇宙中广泛存在,其BH质量很大。为了形成BH-NS/BH系统的形成,已经调用了两种主要场景,包括银河场中孤立的二进制演化以及密集环境中的动态相互作用。在这里,我们建议,如果BH-NS/BH系统是由孤立的二进制进化形成的,则由于伴侣BH的积聚反馈,与第二核塌陷相关的超新星信号(SN)信号将显示出一些可识别的特征。根据二进制属性,我们表明,SN灯库可能会在$ \ sim10 $天堂呈现一个尖峰的峰值,即使在超级发光SNE的级别(例如$ \ sim10^{44}〜\ rm erg〜s^{ - 1} $)或在corce corce corce corce corce corce corce的持续时间持续的持久功能。将这些特殊SN信号的事件速率密度与检测到的BH-NS/BH系统的事件速率密度与事件速率密度进行比较,可以帮助区分BH-NS/BH形成通道。

The gravitational-wave detection by the LIGO-Virgo scientific collaboration shows that the black hole and neutron star (BH-NS) or BH-BH systems with a BH mass of tens of solar masses widely exist in the universe. Two main types of scenarios have been invoked for the formation of BH-NS/BH systems, including isolated binary evolution in galactic fields and dynamical interactions in dense environments. Here we propose that if the BH-NS/BH systems are formed from isolated binary evolution, the supernova (SN) signal associated with the second core collapse would show some identifiable features, due to the accretion feedback from the companion BH. Depending on the binary properties, we show that the SN lightcurve could present a sharp peak around $\sim10$ days, with luminosity even at the level of the super luminous SNe ( e.g. $\sim10^{44}~\rm erg~s^{-1}$) or present a plateau feature lasting for several tens of days with regular luminosity of core collapse SNe. Comparing the event rate density of these special SN signals with the event rate density of LIGO-Virgo detected BH-NS/BH systems could help to distinguish the BH-NS/BH formation channel.
