This award will fund a theoretical effort to model the outer layers of neutron stars. The principal goals of the research are (1) to generate models of the neutron star inner crust that will handle nuclear reactions with realistic treatment of nuclear composition; (2) to determine how the crust evolves in an accreting environment and to connect observed surface phenomena with the properties of the deep interior; and (3) make predictions about the extent to which the neutron star crust can be deformed in accretion and to compute the expected gravitational wave signals.Neutron stars are the densest objects in the universe and knowledge of neutron star physics is growing rapidly, due to X-ray telescopes, laboratory nuclear experiments, and future gravitational wave detectors such as the Laser Interferometer Gravitational Wave Observatory. A recent National Academy report, "Connecting Quarks with the Cosmos: Eleven Science Questions for the New Century," identified the nature of matter at exceedingly high density and temperature as one of the eleven critical science questions for the 21st century.

该奖项将资助一项建立中子星外层模型的理论工作。 研究的主要目标是：（1）建立中子星星内壳模型，该模型将处理核反应，并对核成分进行实际处理;（2）确定壳在吸积环境中如何演变，并将观测到的表面现象与内部深处的性质联系起来;以及（3）预测中子星星壳在吸积过程中的变形程度，并计算预期的引力波信号。中子星是宇宙中最密集的天体，也是中子星星物理学的知识由于X射线望远镜、实验室核实验和未来的引力波探测器（如激光干涉引力波天文台）的出现，美国国家科学院最近的一份报告《连接夸克与宇宙：新世纪的11个科学问题》指出，在极高密度和温度下物质的性质是21世纪的11个关键科学问题之一。
