Dynamic Accretion Discs in Astrophysics

Summary

Accretion discs are a basic building block of many astrophysical systems. The discs that are observed around young stars are where planets form, and those found around white dwarfs, neutron stars and black holes generate spectacular luminosities and variability. It is now possible to develop sophisticated numerical models for the behaviour of these discs, but there is still much to be understood. This project seeks to develop our understanding of accretion disc dynamics through both analytical and numerical modelling. This will build on our existing research using state-of-the-art numerical simulation codes on both local and national high-performance computing (HPC) facilities. The aim is to develop theoretical models that can be used to understand observational data from accreting systems. Accretion discs are fundamental to many astrophysical systems, so we anticipate applying these models to a range of systems from protoplanetary discs around young stars to matter orbiting black holes.

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
