Scientific paper

A stochastic stellar atmosphere model which simulates the behavior of photons in the atmospheres of stars by following individual photons is described and tested. The model accounts for stellar turbulence, atmospheric curvature, stellar rotation, collisional excitation, collisional de-excitation, and stellar winds. Testing shows that this new method of stellar radiative transfer is successful in simulating all of the processes. Particular results of interest include simulation of solar limb darkening and spectral synthesis of three different solar absorption lines.
