[Mesa-users] Error in modelling for pp chain( ierr from write_star_job)

[Piyush Kumar]

Hi!!
Suppose I want to study relation between mass of star and luminosity near ZAMS, (ZAMS radii and luminosities).
So for e.g. I like to do this for mass range 1-10( in Msun units), then is it right that all I need to do is take my initial_mass greater than or equal to 10 for required result? (What I know about the mass x-axis is that each value is a point in the star corresponding to a shell which contains that much mass inside it.)
Thanks..
Best,
Piyush.

The two key file types are history files, which store the value of scalar quantities (e.g. mass, luminosity) at different timesteps and profile files which store the value of spatially varying quantities (e.g. density, pressure) at a single timestep.  Correspondingly, the PGSTAR plots with "profile" in their name are for plotting profile data and the ones with "history" are for plotting history data.
