What is MESA?

MESA provides a modern software infrastructure for sustained innovation in the stellar astrophysics community. MESA solves the 1D fully coupled structure and composition equations governing stellar evolution with an implicit finite volume scheme. State-of-the-art modules provide adaptive mesh refinement, sophisticated timestep controls, non-adiabatic oscillation capabilities, equation of state, opacity, nuclear reaction rates, element diffusion, boundary conditions, and changes to the mass of the star. The journal papers describing MESA can be found here (Paxton et al. 2011), here (Paxton et al. 2013), and here (Paxton et al. 2015). Since its inception, MESA has attracted over 800 registered users becoming one of the leading numerical tools for stellar astrophysics!

What is the stopping criterion for my MESA-Web submission?

Each calculation runs for 4 hours, or until iron core collapse, whichever comes first.
