论文摘要
WR恒星的发射线光谱通常完全在光学厚的恒星风中形成。因此，在光谱分析中对风速定律的任何假设都会对恒星参数的确定产生深远的影响。通过比较使用不同$β$定律计算的Potsdam Wolf-rayet（Powr）模型光谱，我们表明速度场很大程度上影响了光谱：通过使用适当的$β$定律，可以用相同的恒星模型覆盖晚期和早期类型的整个范围。
The emission line spectra of WR stars are often formed completely in the optically thick stellar wind. Hence, any assumption on the wind velocity law in a spectral analysis has a profound impact on the determination of the stellar parameters. By comparing Potsdam Wolf-Rayet (PoWR) model spectra calculated with different $β$ laws, we show that the velocity field heavily influences the spectra: by using the appropriate $β$ laws, the entire range of late and early types can be covered with the same stellar model.
