  • Mallik, S. G. V (American Astronomical Society, 1993-01-01)
    CCD echelle spectra of the H-alpha line at 6563 A have been obtained for a sample of 30 G and K supergiants with a spectral resolution of about 0.24 A. The data clearly indicate that the observed H-alpha profile is a deep ...
  • Mallik, S. G. V (Royal Astronomical Society, 1986-09)
    The radiative transfer problem in non-LTE moving atmospheres has been explicitly solved for Hα line profiles. These computations have been done for a schematic model of the line-forming region over a wide range of optical ...
