Abstract

We calculate models of extended stellar atmospheres with a temperature in the range of 12 000–40 000 K and a mass loss rate of \({{10}^{{ - 6}}}\)–\({{10}^{{ - 4}}}{{M}_{ \odot }}\)\({{{\text{yr}}}^{{ - 1}}}\). A large number of objects with emission spectra, such as luminous blue variables, FeII—emission line stars, Of/late-WN stars, and even ultraluminous X-ray sources often have effective temperatures in this range. The paper presents the results of model grids calculating in the form of equivalent width diagrams for the selected lines of hydrogen, He, Si, and Fe, as well as the results of studies of some emission objects using the calculated models.

温度低于40000 K的扩展大气建模

摘要

我们计算温度在12000-400000 K范围内且质量损失率为\（{{10} ^ {{ --6 }}} \） – \（{{10} ^ {{-4}}} {{M} _ {\ odot}} \）\（{{{\ text {yr}}} ^ {{-1-}}} \）。大量具有发射光谱的物体，例如发光的蓝色变量，FeII-发射线恒星，Of / late-WN恒星，甚至超发光的X射线源，通常都具有此范围内的有效温度。本文以氢，氦，硅和铁的选定线的等效宽度图的形式给出了计算模型网格的结果，以及使用计算模型对某些排放物进行研究的结果。
