A new and exciting era of astronomy is about to begin, where ripples in gravity itself are used to probe the Universe. A prime target of this gravitational wave astronomy are neutron stars - small dense stars capable of rotating hundreds of times a second. It has been proposed that a neutron star in a binary system might emit gravitational waves, but only if it is deformed away from axisymmetry in some way. The aim of this project is to look at the complex interplay of gravity, hydrodynamics, elasticity and nuclear physics at work in in these stellar systems, to see under what conditions such a non-axisymmery might be formed. The output of this research would guide the efforts of gravitational wave astronomers, and could allow us to use neutron stars as nuclear physics laboratories, probing regimes inaccessible to terrestrial experimenters.

一个令人兴奋的天文学新时代即将开始，引力本身的涟漪将被用来探测宇宙。引力波天文学的主要目标是中子星——一种每秒旋转数百次的致密小恒星。有人提出，双星系统中的中子星可能会发射引力波，但前提是它以某种方式偏离轴对称。这个项目的目的是研究重力、流体力学、弹性和核物理在这些恒星系统中复杂的相互作用，看看在什么条件下可能形成这种非轴对称。这项研究的成果将指导引力波天文学家的工作，并使我们能够利用中子星作为核物理实验室，探索地球上的实验人员无法进入的体制。
