[mesa-users] Building stars via accretion with MESA

[Masanobu Kunitomo]

Dear Richard,

I will submit a paper on this subject shortly! Our work is similar to Baraffe et al. (2009, 2012) and Hosokawa et al. (2011), i.e., considering the accretion from a second core (~1-10 Mjup) to the final mass raging 0.05 to 1Msun and the heat injection by accretion parameterized with the “energy_routine” in src/run_star_extras.f. If you have any questions, I’ll be pleased to help.

Cheers,
Masanobu
