Abstract

The determination of photospheric abundances in late-type stars from spectroscopic observations is a well-established field, built on solid theoretical foundations. Improving those foundations to refine the accuracy of the inferred abundances has proven challenging, but progress has been made. In parallel, developments on instrumentation, chiefly regarding multi-object spectroscopy, have been spectacular, and a number of projects are collecting large numbers of observations for stars across the Milky Way and nearby galaxies, promising important advances in our understanding of galaxy formation and evolution. After providing a brief description of the basic physics and input data involved in the analysis of stellar spectra, a review is made of the analysis steps, and the available tools to cope with large observational efforts. The paper closes with a quick overview of relevant ongoing and planned spectroscopic surveys, and highlights of recent research on photospheric abundances.

太阳和恒星的光球丰度
通过光谱观测确定晚型恒星的光球丰度是一个建立在坚实理论基础上的成熟领域。事实证明,改进这些基础以提高推断丰度的准确性具有挑战性,但已经取得了进展。与此同时,仪器的发展,主要是关于多目标光谱学,已经取得了惊人的进展,许多项目正在收集银河系和附近星系的大量恒星观测数据,有望在我们对星系形成和演化的理解方面取得重要进展。在简要介绍了恒星光谱分析的基本物理和输入数据后,回顾了分析步骤,以及处理大型观测工作的可用工具。本文最后简要概述了相关的正在进行的和计划中的光谱调查,并强调了最近对光球丰度的研究。
