标题： Towards 21st Century Stellar Models: Star Clusters, Supercomputing, and Asteroseismology

摘要： 恒星模型为天文学和天体物理学的许多方面提供了至关重要的基础。近年来，通过恒星振荡学、精确测光、高分辨率光谱学以及大规模巡天观测，观测天文学取得了长足进步，这使得恒星模型受到了前所未有的定量审视。模型的局限性逐渐显现，迫切需要下一代恒星模型。当前模型中的不确定性会传播到恒星演化的后期阶段，阻碍了我们对恒星群体和化学演化的理解。 在此，我们简要概述了核心氦燃烧恒星的演化、重要性以及显著的不确定性，然后简要讨论了我们在推进建模工作时采用的各种理论和观测方法。 显示英文摘要

摘要： Stellar models provide a vital basis for many aspects of astronomy and astrophysics. Recent advances in observational astronomy -- through asteroseismology, precision photometry, high-resolution spectroscopy, and large-scale surveys -- are placing stellar models under greater quantitative scrutiny than ever. The model limitations are being exposed and the next generation of stellar models is needed as soon as possible. The current uncertainties in the models propagate to the later phases of stellar evolution, hindering our understanding of stellar populations and chemical evolution. Here we give a brief overview of the evolution, importance, and substantial uncertainties of core helium burning stars in particular and then briefly discuss a range of methods, both theoretical and observational, that we are using to advance the modelling.
