论文摘要
当大量的星星祖细胞周围存在着密集的室内介质（CSM）时，我们认为在失败的超新星中的黑洞形成。通过利用辐射流体动力学模拟，我们计算了在塌陷阶段蓝色超级巨人和狼射线星的质量射出，以及射出和环境CSM之间发生的辐射冲击。 We find that the resultant emission is redder and dimmer than normal supernovae (bolometric luminosity of $\sim 10^{40}-10^{41}\ {\rm erg\ s^{-1}}$, effective temperature of $\sim 5\times 10^3$ K, and timescale of 10-100 days) and shows a characteristic power-law decay, which may comprise a fraction包括2017年在内的中间发光红色瞬变（ILRT）。除了在档案数据中搜索祖细胞之星外，我们还鼓励对此类ILRT $ \ sim $ \ sim $ 1-10岁的X射线随访观察，以后返回积聚磁盘为目标。
We consider black hole formation in failed supernovae when a dense circumstellar medium (CSM) is present around the massive star progenitor. By utilizing radiation hydrodynamical simulations, we calculate the mass ejection of blue supergiants and Wolf-Rayet stars in the collapsing phase and the radiative shock occurring between the ejecta and the ambient CSM. We find that the resultant emission is redder and dimmer than normal supernovae (bolometric luminosity of $\sim 10^{40}-10^{41}\ {\rm erg\ s^{-1}}$, effective temperature of $\sim 5\times 10^3$ K, and timescale of 10-100 days) and shows a characteristic power-law decay, which may comprise a fraction of intermediate luminosity red transients (ILRTs) including AT 2017be. In addition to searching for the progenitor star in the archival data, we encourage X-ray follow-up observations of such ILRTs $\sim$ 1-10 yr after the collapse, targeting the fallback accretion disk.
