红超巨星的质量损失:大质量恒星最终演化的关键因素

Mass loss of red supergiants: a key ingredient for the final evolution of massive stars

Cyril Georgy, Sylvia Ekström

摘要:

从观测或理论的观点来看,红超巨星阶段的质量损失率受到的限制非常少。然而,它们可以非常高,并使大质量恒星在这一阶段失去大量质量,大大影响恒星的最终演化:它最终会成为红超巨星吗?它会通过移除富含氢的外壳而向蓝色进化吗?在本文中,我们简要总结了这种质量损失和相关的不确定性的影响,特别是对蓝超巨星的人口。

英文摘要:

Mass-loss rates during the red supergiant phase are very poorly constrained from an observational or theoretical point of view. However, they can be very high, and make a massive star lose a lot of mass during this phase, influencing considerably the final evolution of the star: will it end as a red supergiant? Will it evolve bluewards by removing its hydrogen-rich envelope? In this paper, we briefly summarise the effects of this mass loss and of the related uncertainties, particularly on the population of blue supergiant stars.
