What kinds of things can MESA do?

For a brief summary of the capabilities of MESA, take a look at this presentation by Matteo Cantiello. (He has also provided a Keynote version.)

The full capabilities of MESA are documented in the instrument papers. Looking through the figures will give you a feel for the broad range of problems that can be studied using MESA.

Additional capabilities are documented by MESA users in their publications

To give you yet more flavor of what MESA can do, here are some movies made using png output from mesa/star.

Evolve a 1 Msun star

This movie has more than you ever wanted to know about the evolution of a 1 Msun star from pre-main sequence to cool white dwarf. (61MB)

Evolve a 2 Msun star

Here is the evolution of a 2 Msun star from He core flash to cool white dwarf with some nice thermal pulses at the tip of the AGB (initial Z = 0.02). (40MB)

Evolve a 16 Msun star

This one shows the evolution of a 16 Msun star from zams to core collapse (initial Z = 0.02 and ZAMS uniform rotation = 0.5 of critical). (13MB)

Accretion onto a neutron star

Now for something completely different, here is a movie showing rapid accretion of pure helium onto a neutron star envelope leading to Type I X-ray bursts. (10MB)

Explosive Nucleosynthesis

This movie shows explosive nucleosynthesis with a 204 isotope net, as discussed in Section 6.2.2 of Paper III. (1.5MB)
