Abstract:
The behaviour of line profiles in the wings of the Balmer, Paschen, and Brackett lines (alpha to delta) has been theoretically investigated in five facular models at disc centre. These profiles have been compared amongst the chosen facular models, and also compared with the photospheric observations. We find that these profiles can distinguish amongst different facular models. It is improving the existing facular models. Efforts should also be made to study faculae right from the ultraviolet to far-infrared.
