With their high spin rates, accreting neutron stars in low-mass X-ray binaries are a potentially detectable source of gravitational radiation. In this project, we aim to model such accreting neutron stars with a view to identifying mechanisms whereby mass asymmetries may develop, which would then produce a long-lived continuous gravitational wave signal. Of particular interest will be the role of the magnetic field in channelling the accretion flow, and modifying the heating and cooling within the star, to see what level of mass asymmetry may result.

低质量X射线双星中的中子星自转速度很高，是一种潜在的可探测到的引力辐射源。在这个项目中，我们的目标是对这种吸积中子星进行建模，以确定质量不对称可能产生的机制，从而产生长期持续的引力波信号。特别令人感兴趣的是磁场在引导吸积流以及改变恒星内部的加热和冷却方面的作用，以观察可能导致的质量不对称程度。
