TOPIC A : Extended Atmospheres (Van Rensbergen W.) - - Atmospheres of early type stars. Computer codes have been developed to calculate non LTE radiative transfer in extended atmospheres; the structure of these atmospheres; occupation numbers of atomic energy levels in these atmospheres; P-Cygni line spectra observed from early type stars with stellar wind; three dimentional line transfer for Be Star envelopes; active Stark effect in ...
