Extract

The model photosphere is the core of the theoretical side of our studies.It is a numerical theory from which we compute the theoretical spectrum to be compared to the observations.Our model photospheres are based on hydrostatic equilibrium.To compute such models, we need the temperature distribution, a value for the surface gravity, and the chemical abundances of the electron donors.This chapter reveals how this process is done.
