摘要:

最近使用先进的中微子输运对II型超新星进行的核合成计算确定,早期的中微子风富含质子。然而,同时喷出的一小部分是由富含中子的口袋组成的。在本文中,我们计算的核合成的贡献,从中子丰富的口袋中的热对流气泡的核心坍缩超新星,并表明,他们没有显着的总核合成。

英文摘要:

Recent nucleosynthesis calculations of Type II supernovae using advanced neutrino transport determine that the early neutrino winds are proton-rich. However, a fraction of the ejecta emitted at the same time is composed of neutron-rich pockets. In this paper we calculate the nucleosynthesis contribution from the neutron-rich pockets in the hot convective bubbles of a core-collapse supernova and show that they do not contribute significantly to the total nucleosynthesis.
