AI 中文摘要
太阳是天文学的基本基准之一，人们对精确测定其化学组成的兴趣日益增长。本文呈现了当前光谱测定太阳元素丰度的最新进展，目前该方法常规采用太阳光球层的三维（3D）辐射流体动力学模拟及非局部热力学平衡（non-LTE）后处理。我们对近期文献进行了批判性综述，给出了83种长寿命元素的当前及原太阳丰度推荐值，并讨论了这些值相对于原始陨石、日震学、中微子流量及太阳模型问题的意义。
英文摘要
The Sun is one of the fundamental benchmarks in astronomy, and there is ever growing interest in precise and accurate determinations of its chemical composition. We present the current state-of-the-art in spectroscopic determinations of the solar elemental abundances, that now routinely employ three-dimensional (3D) radiative-hydrodynamic simulations of the solar photosphere and post-processing in non-local thermodynamic equilibrium (non-LTE). We critically review the recent literature and present recommended present-day and protosolar abundances of the 83 long-lived elements, and discuss their implications vis-à-vis primitive meteorites, helioseismology, neutrino fluxes, and the Solar Modelling Problem.
