[mesa-users] Convergence of models in the 11 - 14 Msun range

[Manos Chatzopoulos]

Dear all,

  Has anyone managed to have a converged MESA model all the way from 
pre-MS to pre-supernova (core-collapse)
in this rather interesting mass range of 11 - 14 Msun? Stars around this 
mass range are thought to make electron-capture
SN progenitors with O/Ne/Mg cores, but when I try running them they 
always seem to fail to converge past
core C/O burning. Is this relevant to the core becoming significantly 
degenerate? Any insight on this would be
appreciated.

Best,

Manos
