The current release consists of masses ranging from 0.1 to 300 solar masses and log(Age) ranging from 5 to 10.3. We're currently working on extending the models down to the brown dwarf regime.

Stars are evolved continuously to central hydrogen depletion, white dwarf cooling sequence, or central carbon depletion depending on the stellar mass.

MIST version 1 adopts solar-scaled abundances from Asplund et al. (2009), with metallicities ranging from [Fe/H] = -4 to 0.5. MIST version 2 adopts the GS98 solar abundance pattern and includes the full range of [Fe/H] and a range of [α/Fe] values.
