Astrophysics group | Astrophysics

About the group

The group carries out research into a wide range of topics involving astrophysical fluid dynamics and nonlinear dynamics. Specific astrophysical interests include the dynamics of astrophysical discs, planetary formation and evolution, extrasolar planetary systems and stellar magnetohydrodynamics (particularly dynamo theory, magnetoconvection and the physics of sunspots).

PhD opportunties

A wide range of possible research topics is available and we welcome enquiries from potential applicants. The closing date for applications is 7 January 2025.

Astrophysical dynamics

Discs are ubiquitous in astrophysics and participate in some of its most important processes. Most, but not all, feed a central mass: by facilitating the transfer of angular momentum, they permit the accretion of material that would otherwise stay in orbit. As a consequence, discs are essential to star, planet and satellite formation. They also regulate the growth of supermassive black holes and thus indirectly influence galactic structure and the intra-cluster medium.

Atomic astrophysics

Atomic physics plays a key role in astrophysics as astronomers' only information about a particular object comes through the light that it emits, and this light arises through atomic transitions. The main astronomical body that we study is the Sun and, in particular, the hot atmosphere of the Sun called the corona. The best parts of the electromagnetic spectrum to study the corona are the extreme ultraviolet (EUV) and X-rays.
