1、恒星结构和演化及星团研究

a. 在过去的二十余年间，太阳元素丰度—太阳模型问题始终是困扰全球恒星物理学者的难题。我们提出利用转动恒星演化的动力学太阳模型来解决这个问题，给出低金属丰度的转动太阳模型很好地再现了日震学反演结果和中微子探测结果。

b 星团颜色星等图的研究。我们的转动恒星演化模型预测的星团颜色星等图主序拐点扩展随年龄变化被观测证实(Yang et al.2013, ApJ,776,112)。

2、星振学

    a、人类有能力建造越来越大的望远镜，观测到越来越远的天体。但再大的望远镜也无法看穿太阳和恒星表面的阻碍。获得和理解隐藏在恒星表面下的结构和物理过程一直是天文学追求的重要目标之一。我们建立起了星振学诊断恒星对流核大小的理论。第一个给出观测确定恒星对流核大小的星振学方法：像蝙蝠能利用回波听清黑暗中的物体那样。我们的理论实现了让我们听清恒星内部的对流核的大小。观测确定主序星对流核存在及大小的星振学公式：

b、提出利用中微子测量和日震学确定pp链核聚变反应截面因子的原理(arXiv: 2405.10472)，得出美国核理论研究所的SF II低估了pp反应截面2%。这个结果和美国橡树岭国家实验室的研究人员利用手征有效场理论计算的结果(arXiv: 2405.0647)完全一致。除了pp反应截面，我们还预测核物理高估了³He—³He反应截面，低估了⁷Be质子捕获截面因子。pp聚变反应截面因子的改正还解释了日震学反演与太阳模型在中心的差异。
