通过建立非球对称星风模型
研究了恒星尘埃的生成
发现在非球对称模型中
恒星更早地生成尘埃.对于较低的质量损失率
由非球对称模型给出的尘埃凝结度远远高于由球对称模型给出的尘埃凝结度.因而
非球对称模型可能给出更高的尘埃产量.对于较高的质量损失率
由于尘埃的凝结度已达到饱和
非球对称模型和球对称模型下
尘埃的凝结度基本一致
对尘埃的产量不会产生大的影响.
We investigate dust formation in aspherical stellar wind.We find that the dust in aspherical stellar wind can form more early than that in spherical stellar wind.For low mass loss rate
the condensational degrees of dust in aspherical stellar wind are much higher than those in spherical stellar wind
which may result in high dust yield.For high mass loss rate
the condensational degrees of dust in aspherical stellar wind are similar with those in spherical stellar wind and the dust yield is hardly affected
due to saturated condensational degrees of dust.
