论文摘要
我们已经分析了质量和绝对Gaia g幅度之间的关系的检索，如\ cite {2012mnras.427..127b}从理论模型中获得的，用于不同的光度类别的星星。对于次级和主要序列恒星，我们根据在给定阶段的进化过程中基于G幅度最可能的值的分析直接和反关系。与（尽管很少）观察数据的比较证实，我们的结果可用于估计GAIA光度法的恒星质量，范围为1至10个太阳能质量。我们认为，其他亮度类别类似的关系并不提供信息。
We have analyzed the retrieval of the relation between mass and absolute Gaia G magnitude as obtained from theoretical models by \cite{2012MNRAS.427..127B} for the stars of different luminosity classes. For subgiant and main-sequence stars, we provide approximate analytical direct and inverse relations based on the most probable value of G magnitude in the course of evolution within the given stage. A comparison with (albeit few) observational data confirms that our results can be used for the estimation of the stellar mass from Gaia photometry in the range of 1 to 10 solar mass. We argue that similar relations for other luminosity classes are not informative.
