About the Group

The group carries out research into a wide range of topics involving astrophysical fluid dynamics and non-linear patterns. Specific astrophysical interests include stellar magnetohydrodynamics (particularly dynamo theory, magnetoconvection and the physics of sunspots), accretion discs, protoplanetary systems, extrasolar planetary systems and galaxy clusters. Many of these areas of research are related to topics in non-linear dynamics, particularly pattern formation and bifurcation theory. More information about the group's research projects is available here. The Atomic Astrophysics group maintains a separate website.

The group's recent publication list and the most cited scientific publications written by group members are updated regularly and give an overview of our research activities.

PhD Applications

We welcome applications for PhD studentships. The group, together with the Atomic Astrophysics Group, has allocated funding from STFC for astrophysics research studentships that are available from October 2014. Studentships are normally allocated around Easter. However, depending on circumstances, some may be advertised at other times. To find out if you are eligible and for further information regarding the application procedure and funding please check out http://damtp.cam.ac.uk/research/astro/about/phd.html.

Some possible projects in astrophysics and potential supervisors are listed on our research pages. Potential supervisors may also be contacted individually. Information relating to research projects undertaken by current PhD students can be found on the group members page where there are also links to personal websites where available.

The above links provide coverage of research activities within the group but please do not hesitate to contact via email Virginia Mullins (Group Secretary) at or one of the staff members listed if you have any other queries or require further information regarding research opportunities within the group.
