Modules for Experiments in Stellar Astrophysics (MESA) is an advanced, open-source 1D stellar evolution code. The code is developed and maintained by a globally distributed team of researchers. MESA is written primarily in Fortran with a modular, flexible design that facilitates easy interfacing.
🚀 New to MESA? Start with the :ref:`Quickstart<quickstart:Quickstart>` guide to set up and run your first models.
- 📖 Experienced users may find the :ref:`Reference and Defaults<reference:Reference and Defaults>`
- page most useful for exploring the code’s features and input parameters. The :ref:`Test Suite<test_suite:Test Suite>` provides example problems for testing and showcasing MESA, serving as a project starting point but often requiring modifications for science-grade accuracy.
