[Mesa-users] How to edit inlist_project and to implement a control of the mass loss?

[Bergerson Van Hallen]

Hi! I'm Bergerson Van Hallen a student of Physics in State University of
Ponta Grossa - Brazil. I use MESA program some time ago, however I have
doubt on how (which way) I can edit the lists with input parameters to make
a simulation perhaps more realistic. My job is with spectroscopy,
photometry and stellar evolutio of the B, Be, and O stars. I would like to
know if it is possible to implement in inlist_project any code or
parameter which
concerns mass loss in these types of stars B and O. I found in controls
defaults examples the following parameter that perhaps could help me, but
I'm note sure:

*Vink_scaling_factor = 0d0. (1)*

Will this be implemented in my inlist_project could you give me a more
realistic result? Obviously, I think that some parameter of mass loss
associated with rotation (more important for Be stars) could result in an
even more realistic simulation for stellar evolution. Does such a parameter
exist in examples in the controls defaults section or in others
inlists_projects? Another question I have is how to implement *(1)* in
inlist_project. I should only put:



































*! For the sake of future readers of this file (yourself included),! ONLY
include the controls you are actually using.  DO NOT include! all of the
other controls that simply have their default values.&star_job  ! begin
with a pre-main sequence model    create_pre_main_sequence_model = .true.
! save a model at the end of the run    save_model_when_terminate =
.false.  ! display on-screen plots    pgstar_flag = .true./ !end of
star_job namelist&controls  ! starting specifications    initial_mass = 1.0
! in Msun units  ! Vink_scaling_factor    Vink_scaling_factor = 0d0.  !
stop when the star nears ZAMS (Lnuc/L > 0.99)    Lnuc_div_L_zams_limit =
0.99d0    stop_near_zams = .true.  ! stop when the center mass fraction of
h1 drops below this limit    xa_central_lower_limit_species(1) = 'h1'
xa_central_lower_limit(1) = 1d-3/ ! end of controls namelist*


and wait until the end of the simulation?

Well, I'm just a beginner in the MESA program and I still do not have
enough skill to manipulate my simulations.

So, from now , I'm very grateful for any explanation or help with my doubts.
