[Mesa-users] Mass loss in low mass star during PMS

[Francis Timmes]

hi roque,

if one has a known mass loss rate to impose, it can be as simple as 

mass_change = value  ! in msun/yr

http://mesa.sourceforge.net/controls_defaults.html#mass_gain_or_loss

something fancier like

      cool_wind_RGB_scheme   = 'Reimers'
      cool_wind_AGB_scheme   = 'Blocker'
      RGB_to_AGB_wind_switch = 1d-4
      Reimers_scaling_factor = 0.1   
      Blocker_scaling_factor = 0.5   

will have a small mass loss during the main sequence, 
which you can test for yourself by examining the history of

star_mdot

According to MESA documentation it seems to me that this process takes only place during the RGB and AGB evolution phases. So, my question is: is it possible to model mass loss in early stages as the PMS and MS of a low mass star? If so, could you let me know which options should I select?
