Summary of Materials science doctoral thesis: Rotational spectral line formation and radiative transfer in circumstellar envelopes

The research in this thesis follows two directions: The first, using high performance computing currently available, we studied atomic and molecular emissions in astrophysical environment. The radiative transfer model was applied to explain the characteristics of the recombination line masers Hnα in the envelope of the star MWC 349A.
