Simulations
For the simulations it was built a column from a late-type star atmosphere in the radial direction, starting at the stellar surface and extending until 300 times the stellar radius.
Cartesian coordinates with y and z symmetry
simulation total time = 2 years
The star gravity was also considered in the simulations, with total mass of the star represented by a point.
The initial conditions were given by STALATYS code (Jatenco-Pereira & Opher 1989).
