聚集对O星风参数预报的影响

The influence of clumping on predicted O star wind parameters

Jiri Krticka, Joachim Puls, Jiri Kubat

摘要:

我们研究了聚集效应对O型星风结构的影响。为了这个目的,我们人为地包括成团到我们的固定风模型。当团块被假设为光学薄,辐射线力增加相比,相应的未成块的模型,具有类似的效果,无论是质量损失率或终极速度(取决于开始的成块)。光学厚的团块,或者,可能能够减少辐射力。

英文摘要:

We study the influence of clumping on the predicted wind structure of O-type stars. For this purpose we artificially include clumping into our stationary wind models. When the clumps are assumed to be optically thin, the radiative line force increases compared to corresponding unclumped models, with a similar effect on either the mass-loss rate or the terminal velocity (depending on the onset of clumping). Optically thick clumps, alternatively, might be able to decrease the radiative force.
