Nova occurs in a close binary system which contain a white dwarf. Nova outburst is triggered by a thermonuclear shell flash on the white dwarf. What determins the speed class of novae has been a longstanding problem. I have answered this problem by making teoretical light curves with wide range of parameters : With the new opacity, optically thick wind theory gives theoretical light curves of novae with high quality that we can compare with the observational data in detail.This light curve analysis is applicable to wide range of nova parameters. The optically thick wind mass loss seriously affects scenarios of binary evolution.

新星出现在一个包含白矮星的封闭双星系统中。新星爆发是由白矮星上的热核壳闪光引发的。是什么决定了新星的速度等级一直是一个长期存在的问题。我通过制作具有广泛参数的理论光变曲线来回答这个问题：利用新的不透明度，光学厚风理论给出了高质量的新星理论光变曲线，我们可以将其与观测数据进行详细比较。这种光变曲线分析适用于广泛的新星参数。光学厚的风质量损失严重影响了双星演化的场景。
