Welcome

Stellar evolution codes can be complicated to use, so we are offering MESA-Web, a web-based interface to the stellar evolution code, Modules for Experiments in Stellar Astrophysics (MESA).

MESA-Web can be used for education purposes to calculate stellar models over a range of physical parameters, extending capabilities of similar online tools such as Rich Townsend's EZ-Web.

On April 30, 2021, the server that hosts MESA-Web will go offline. We are working to transfer MESA-Web to a new home that also hosts more computational resources that allow users to run more jobs. In the mean time, be sure to keep an eye out on the MESA-Users Mailing list for updates about when MESA-Web is back online. Thank you for your patience!
