The determination of stellar chemical compositions is important in astrophysics because it allows us to address the question: how do planets, stars, and galaxies evolve? This project will apply the latest generation of three-dimensional stellar models to the interpretation of stellar spectra and to the derivation of elemental abundances in stars.

恒星化学成分的测定在天体物理学中很重要，因为它使我们能够解决这个问题：行星、恒星和星系是如何进化的？该项目将应用最新一代的三维恒星模型来解释恒星光谱和推导恒星中的元素丰度。
