Add to ORKGAn investigation of the atmospheric structure of non-Mira, asymptotic giant branch stars through NLTE radiative transfer modeling applied to hydrodynamic models is discussed. Synthetic spectra resulting from these calculations were compared with IUE observations of these stars to test the validity of the models. The development of the hydrodynamic models is detailed
