黑洞风中的r过程
The r-Process in Black Hole Winds
摘要：
目前所有与核心坍缩超新星有关的r过程方案都面临着严重的困难。特别是，最近的核心坍缩模拟与中微子传输显示没有迹象表明一个富含中子的风从原中子星。在本文中，我们讨论了另一个天体物理站点，“黑洞风”，这是中微子驱动的流出从吸积环周围的黑洞的r-过程的核合成。这个条件被假定在双中子星合并、中子星-黑洞合并或超新星中实现。
英文摘要：
All the current r-process scenarios relevant to core-collapse supernovae are facing severe difficulties. In particular, recent core-collapse simulations with neutrino transport show no sign of a neutron-rich wind from the proto-neutron star. In this paper, we discuss nucleosynthesis of the r-process in an alternative astrophysical site, "black hole winds", which are the neutrino-driven outflow from the accretion torus around a black hole. This condition is assumed to be realized in double neutron star mergers, neutron star - black hole mergers, or hypernovae.
