摘要: Abstract We aim to demonstrate the effect of atmospheric inhomogeneities on emergent specific intensity and radiation flux a spectral line radiation. self-consistently solve NLTE problem for two-level atom in 3D atmosphere using Cartesian grid. For that purpose, we use radiative transfer code PORTA. By examining simple examples, study cases where temperature models lead modification show model atmospheres influence emerging radiation, interpretation stellar spectra based plane-parallel can erroneous conclusions about structure.
