论文摘要
我们介绍了使用sculptor Group Galaxy NGC 300中B和A型超级巨头和A型超级巨头和明亮的巨人的中间分析多单位光谱探索器（MUSE）获取的光谱数据获得的结果。为我们的分析，是一种混合本地热力学平衡（LTE）线路+非ll-l-l-ltte的分析。此外，我们还提供了这项工作的一些进一步应用，其中包括扩展磁通加权的重力光度关系（FGLR），这是超级巨人的距离测定方法。这项开创性的工作为探索这种关系打开了一个新的窗口，还展示了整体田间光谱法（IFS）对静脉外定量恒星研究的巨大潜力。
We present the results obtained using spectroscopic data taken with the intermediateresolution Multi Unit Spectroscopic Explorer (MUSE) of B and A-type supergiants and bright giants in the Sculptor Group galaxy NGC 300. For our analysis, a hybrid local thermodynamic equilibrium (LTE) line-blanketing+non-LTE method was used to improve the previously published results for the same data. In addition, we present some further applications of this work, which includes extending the flux-weighted gravity luminosity relationship (FGLR), a distance determination method for supergiants. This pioneering work opens up a new window to explore this relation, and also demonstrates the enormous potential of integral field spectroscopy (IFS) for extragalactic quantitative stellar studies.
