[mesa-users] dynamo effect on stellar str

[Valery Pipin]

Dear  List,

I wonder if MESA has a possibility to check effects of large-scale 
magnetic field and flow on the stellar structure.

I have computed a set of nonlinear dynamo models. They include the 3D 
mean-field dynamo coupled with angular momentum balance and heat transport.

The model use the reference thermodynamic  structure of a star 0.3Ms of 
age 1Gyr  which was computed with help of MESA using the solar composition.

The equation for the mean-field heat transport was solved for 
perturbation of the mean entropy caused by effects of the global 
rotation and magnetic field.

In 1D stellar structure code the effect of mixing due to meridional 
circulation can be treated as an addition to diffusion and effect of 
magnetic field via the averaged addition to pressure.

Both factors vary along the radius. Can I add them to the code and in 
what place. I would appreciate if you have some example.

The test suite contains example for 15M star with dynamo. I don't 
understand where parameters of the magnetic field are defined?

Thanks

Valery
