不透明度对Ia超新星极大光度的影响

Effect of Opacity on the Maximum Absolute Bolometric Magnitude of Ia Supernova

在Arnett’s rule基础上,通过考察Ia超新星光极大时的物理情形,计算修正因子,并讨论不透明对修正因子的影响.结论表明用Arnett’s rule估计出的Ia超新星光极大时的光度(观测光度)偏低,在一定条件下修正因子对极大时的光度有重要影响.

Based on the Arnett＇s rule,this paper studies the physical picture of the maximum absolute bolometric magnitude of supernova, deducts the correction factor to maximum luminosity, and discuses the influence of opacity on correction factor. It turns out that the luminosity is lower according to Arnett＇s ruler, and correction factory is important to the maximum luminosity.
