This award will support a theoretical project to model neutron star structure and to explore the consequences for observations of such objects. Neutron stars are the dead remnants of moderately massive stars, and have extremely high densities. The main goal of the work is to develop realistic models of the rotational and crust dynamics of neutron stars, and to explore (1) the observable effects of superfluid turbulence, (2) the coupling of the crust to the interior of the neutron star, and (3) how the deep crust responds to shear stresses.Dr. Link will also continue his longstanding efforts to enhance in teaching and training, improve infrastructure for education and research, and undertake outreach and engagement activities with the local community. The project is also expected to have an impact in the theoretical understanding of matter at high density and of nuclear interactions in conditions not achievable in terrestrial laboratories.

该奖项将支持一个理论项目，以模拟中子星星结构，并探索观测此类物体的后果。 中子星是中等质量恒星的死亡残余物，具有极高的密度。 研究的主要目标是建立中子星自转和地壳动力学的真实模型，并探索（1）超流体湍流的可观测效应，（2）地壳与中子星星内部的耦合，以及（3）地壳深部如何对剪切应力作出反应。林克博士还将继续他长期以来的努力，以加强教学和培训，改善教育和研究基础设施，并与当地社区开展外联和接触活动。 预计该项目还将对从理论上理解高密度物质和在陆地实验室无法实现的条件下的核相互作用产生影响。
