The work directory already contains a set of simple configuration files that will evolve a 15 solar mass star through on to the zero-age main sequence (core hydrogen ignition). Also, Im not PLEASE CHECK THE OTHER VERSIONS OF THIS RECORD. The entire process of stellar evolution is playing out in self-gravitating spherical systems with mass M and radius R, where there is a relationship between the gravitational self-energy of the system and the thermal energy in the gas. The readmesa.py script was used to plot data from the profile files in terms of the radius of the star in solar radii. This function is bound to C-c C-t by default. profilennn.data or lognnn.data files are profile data files.

In contrast, MESA is large, flexible, open-source, slower, high-cost in memory, maintained on a centralized, open-access platform (GitHub), has exceptionally broad coverage of the stellar mass and metallicity regimes, and has a large and active user base comprising experts with a diverse array of astrophysical specializations as well as novices.
