红超巨星质量损失对超新星喷出物和环暴介质的影响

The effects of red supergiant mass loss on supernova ejecta and the circumburst medium

Jacco Th. van Loon

摘要:

大质量恒星成为红超巨星时,在这短暂的演化阶段会失去大量的质量。然后,它们要么爆炸为富氢超新星(SN II型),要么继续演化为更热的超巨星(爆炸前)。红超巨星缓慢的尘埃喷出物将被炽热的星风和/或SN喷出物所淹没。我将提出这种相互作用的条件的估计,并讨论一些影响。

英文摘要:

Massive stars becoming red supergiants lose a significant amount of their mass during that brief evolutionary phase. They then either explode as a hydrogen-rich supernova (SN Type II), or continue to evolve as a hotter supergiant (before exploding). The slow, dusty ejecta of the red supergiant will be over-run by the hot star wind and/or SN ejecta. I will present estimates of the conditions for this interaction and discuss some of the implications.
