星周盘对Ⅰa型超新星前身星演化的影响
The Influence of the circumbinary disk on the evolution of progenitor of Type Ⅰa Supernovae
摘要
Abstract
We have calculated the evolution of close binaries consisting of a white dwarf and a main - sequence or subgiant companion. In the evolution, we assume that a small fraction of the lost material from the system forms a circumbinary （CB） disk, which extracts the orbital angular momentum from the system through tidal torques. Our calculations indicate that the existence of a eircumbinary disk can enhance the material transfer rate, and then, the white dwarf may grow in mass efficiently to trigger Type Ia supernovae （SNe Ⅰa）. However, the effect of CB disk on the birth rate of SNe Ⅰa is insignificant.关键词
