I use eclipsing binaries to study the fundamental properties of low-mass stars, extra-solar planets and brown dwarfs.
I also study the evolution of interacting binaries like cataclysmic variables.
The variability of very low mass stars and brown dwarfs has a mysterious origin. Dust cloud weather, magnetic activity and powerful aurora may all play a role.
I use infrared and optical observations to understand the origins and implications of variability.
Time-domain astrophysics requires specialist tools!
I work with colleagues at Sheffield, Warwick and Durham to build specialist cameras and telescopes to study astrophysics on the fastest timescales.
A series of problem classes to accompany the second year astronomy modules PHY 241, PHY 242, PHY 216 and PHY 229.
An introduction to observational astronomy and Python programming. It supersedes the old observational astronomy course PHY217.
The course website gives details of timetabling, whilst detailed notes are available online.
Python notebooks for the programming sessions can be viewed and downloaded here.
