Abstract:
    Atmosphere study of the giant 20 Peg was investigated using
    high-resolution spectra.

Description:
    The observations were acquired with the 2.6m reflector of the Crimean
    Astrophycal Observatory using an American-made EEV15-11 CCD array
    (1024x256 pixels) in September-October, 1995 and in January and
    October, 1999.
