我们研究了正常超新星和超新星期间中微子-核相互作用对氟产生的影响，并讨论了[F/Fe，Ne，O]的恒星质量、金属度和爆炸能量的关系。我们发现[F/Fe，O，Ne]随恒星质量和爆炸能量的变化趋势明显，而与金属度的变化趋势不明显。通过与观测丰度的比较，[F/O]的这种趋势可以用来约束贡献的恒星质量。
We investigate the effects of neutrino-nucleus interactions on the production of Fluorine during normal supernovae and hypernovae, and discuss stellar mass, metallicity and explosion energy dependence of [F/Fe,Ne,O]. We find the clear trend of [F/Fe,O,Ne] with stellar mass and explosion energy, while no clear trend with metallicity. This trend of [F/O] can be used to constrain the contributed stellar mass by comparing with the observational abundance.
