恒星大气物理参数的信息对我们研究恒星和银河系的结构和演化有重要意义。由于多目标光纤光谱仪的发展,人类获取恒星光谱的数量有了极大的增加。但由于这些光谱数量众多,天文学家快速而又精确的提取相应的恒星大气物理参数有很多困难。为此,天文学家发展了一系列新的方法提取恒星的大气物理参数。本文总结了目前主要的恒星大气物理参数估计方法,并对以后可能的重点研究方向给出了建议。
The information of the stellar atmospheric parameters is important for us to study the structure and evolution of stars and the Galaxy. With the development of multi- object fiber spectroscopic telescope,the number of stellar spectra has greatly increased.However,it is difficult for us to extract stellar atmospheric parameters from these massive spectra data.To overcome this difficult,the astronomers have developed a series of new methods to extract the physical parameters of stars and the abundance of α elements. In this paper,the main methods of extracting the stellar atmospheric parameter are summarized.
