[Mesa-users] Magnetic field with MESA

[Francis Timmes]

a search of $MESA_DIR/star/defaults/profile_columns.list 
suggests that putting

   dynamo_log_B_r   ! (Gauss)
   dynamo_log_B_phi ! (Gauss)

will put the magnetic field info in the profiles.

For the case of the magnetic field, I think it is included following the Spruit-Tayler dynamo model (see MESA Paxton article et al. 2013, section 6.2) that corresponds to the option “am_nu_ST” of the inlist_project file, but I hoped that someone could confirm me this. I would also like to know if there is any way to obtain the value of the magnetic field in the output files.
