摘要:

大质量恒星对周围环境有很强的影响,特别是当它们在演化结束时产生核心坍缩超新星时。在这些论文中,我们回顾了大质量恒星的一般演化和它们在坍缩时的性质,以及大质量恒星和中等质量恒星之间的过渡。我们还总结了金属丰度和旋转的影响。然后,我们讨论了一些主要的不确定性,在大质量恒星的建模,特别强调在一维恒星演化代码对流的治疗。最后,我们提出了新的三维流体动力学模拟碳燃烧对流,并列出了关键点,从三维流体动力学研究的发展新的处方对流边界混合的一维恒星演化代码。

英文摘要:

Massive stars have a strong impact on their surroundings, in particular when they produce a core-collapse supernova at the end of their evolution. In these proceedings, we review the general evolution of massive stars and their properties at collapse as well as the transition between massive and intermediate-mass stars. We also summarise the effects of metallicity and rotation. We then discuss some of the major uncertainties in the modelling of massive stars, with a particular emphasis on the treatment of convection in 1D stellar evolution codes. Finally, we present new 3D hydrodynamic simulations of convection in carbon burning and list key points to take from 3D hydrodynamic studies for the development of new prescriptions for convective boundary mixing in 1D stellar evolution codes.
