摘要:

质量损失仍然是恒星演化的主要不确定性之一。在质量最大的恒星中,质量损失决定了星周介质,并能显著改变恒星的命运。质量损失是由各种风机制和二元相互作用引起的。超新星是这种质量损失的最佳探测器,既包括星周物质,也包括富氢包层的减少质量。在本文中,我们专注于减少氢包层质量对超新星光变曲线的影响,研究了各种质量损失情况下的冲击爆发和峰值光变曲线发射。尽管这种质量损失的趋势会被不同的祖先、爆炸能量和星周介质引起的变化所掩盖,但这些趋势对超新星调查中应该看到的超新星光变曲线有重大影响。最后,我们将我们的结果与几个关键观察结果进行了比较。

英文摘要:

Mass loss remains one of the primary uncertainties in stellar evolution. In the most massive stars, mass loss dictates the circumstellar medium and can significantly alter the fate of the star. Mass loss is caused by a variety of wind mechanisms and also through binary interactions. Supernovae are excellent probes of this mass loss, both the circumstellar material and the reduced mass of the hydrogen-rich envelope. In this paper, we focus on the effects of reducing the hydrogen-envelope mass on the supernova light curve, studying both the shock breakout and peak light curve emission for a wide variety of mass loss scenarios. Even though the trends of this mass loss will be masked somewhat by variations caused by different progenitors, explosion energies, and circumstellar media, these trends have significant effects on the supernova light-curves that should be seen in supernova surveys. We conclude with a comparison of our results to a few key observations.
