白矮星周围吸积盘的光谱

Spectra of accretion discs around white dwarfs

Irit Idan, Jean-Pierre Lasota, Jean-Marie Hameury, Giora Shaviv

摘要:

本文用改进和更新后的Sauvov & Wehrse(1991)模型计算了白矮星周围吸积盘的光谱。新版本包括线不透明度和对流能量传输,并可用于计算光谱的热盘在明亮的系统(新星-类变量或矮新星爆发),以及光谱的冷吸积盘在静止的矮新星。

英文摘要:

We present spectra of accretion discs around white-dwarfs calculated with an improved and updated version of the Shaviv & Wehrse (1991) model. The new version includes line opacities and convective energy transport and can be used to calculate spectra of hot discs in bright systems (nova--like variables or dwarf novae in outburst) as well as spectra of cold accretion discs in quiescent dwarf novae.
