On the Dynamics of Noncircular Accretion Discs

埃利奥特·林奇将在剑桥大学应用数学和理论物理系攻读博士学位。他的研究将是由可变椭圆轨道组成的偏心天体物理盘的流体动力学。他将使用创新的哈密顿方法和数值技术来理解偏心盘的非线性行为，包括它们的非流体静力垂直结构。他还将研究这些系统中的耗散过程，并将该理论应用于双星和黑洞，以及恒星在星系中心黑洞周围被撕碎的潮汐破坏事件。

Elliot Lynch will carry out research towards a PhD degree in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge. His research will be on the fluid dynamics of eccentric astrophysical discs composed of variably elliptical orbits.He will use innovative Hamiltonian methods and numerical techniques to understand the nonlinear behaviour of eccentric discs, including their non-hydrostatic vertical structure. He will also investigate dissipative processes in these systems and will make applications of the theory to binary stars and black holes, as well as tidal disruption events in which stars are shredded around black holes at the centres of galaxies.
