Featured Research


Irradiated Brown Dwarf Circulation

A really extreme planetary system

Graham Lee and co-workers, including fellow EXOCONDENSE team members Xianyu Tan, Mark Hammond and Shami Tsai, carry out the first 3D global circulation model of an irradiated brown dwarf. The brown dwarf is WD0137-349B, and is in a two-hour orbit about a white dwarf star with a photospheric temperature of 16,500K. The brown dwarf is very highly irradiated, giving it some characteristics similar to planets, and the high stellar temperature means that the UV irradiation is very intense.

Io Crust

Magmatic intrusions control Io's crustal thickness

Dan Spencer, Richard Katz and Ian Hewitt explore how flow of magma through Io's crust controls the crustal thickness.
