[mesa-users] Gravity effects

[Bill Paxton]

Hi,

You can set the gravitational "constant" on a cell-by-cell basis, and modify it at each step of the evolution to reflect changing conditions (such as radius).  Do this by setting the entries in the 'cgrav' vector from your run_star_extras.  

Cheers,
Bill

Mostly if a star in a more dense region evolves differently than a star in a less dense region. I was thinking about changing the force of gravity acting on the star to model as the force of gravity from other objects around the star acting on it. I can try to explain my idea more if needed.
