Non-linear radiative transfer model of SW Andromedae

Creators

Description

The following parameters were used to develop a model of SW And.: Log L/L/sub sun/ = 1.6, Log T/sub eff/ = 3.835 and M = 0.6 M/sub sun/. Variable Eddington radiative transfer coupled hydrodynamic calculations, for gray and multi-group Cox-King (King-1A) mixture, were completed. In a comparison of the numerical results to observations, it appears that a multi-frequency radiative transfer calculation is needed since improvements in the B-V, log T/sub eff/ relation are obtained. It is proposed to use these atmospheres in a non-LTE line transfer code in order to make the more direct connection to observations. (auth)
