Window To The Stars

For Outreach, for Teaching, for Research.

We present Window To The Stars, a graphical user interface to the popular TWIN single/binary stellar evolution code, for novices, students and professional astrophysicists. It removes the drudgery associated with the traditional approach to running the code, while maintaining the power, output quality and flexibility a modern stellar evolutionist requires. It is currently being used for cutting edge research and interactive teaching.

Many thanks to Peter Eggleton, Evert Glebbeek, Ghina Halabi, Gemma Kerr and Michael Armstrong for their generous help with the project.

If you have trouble installing, please first Read The FAQ and then contact Robert Izzard at the address below.

Downloads: Latest stable version 2.0
