The Chemical Composition of Stars
Abstract
A review is presented of how advances in astronomical spectrometers are providing opportunities for stellar spectroscopists to address a wide variety of problems of stellar nucleosynthesis and evolution. Three major topics are addressed in detail: (1) important astrophysical problems whose solutions are dependent on accurate data on stellar chemical compositions; (2) the stellar spectra that are basic ingredients with which an abundance analysis commences; and (3) the methods and associated tools of the abundance analysis that are applied to the stellar spectra and other observations, such as photometry, to obtain the abundances. These tools include a library of atomic and molecular data and model stellar atmospheres.
