  • New identifications of YO and CeO in R Cygni 
    Murty, P. S (Gordon and Beach, Science Publishers, 1982)
    New molecular features due to YO and CeO arc reported present in the spectrum of pure S star R Cyg near minimum light. Of the nearly 60 unidentified features listed in the 4620-6420Å region, 10 with YO and II with CeO are ...
  • On the radii of Ap and Am stars 
    Babu, G. S. D; Shylaja, B. S (D. Reidel Publishing Co., 1983-01)
    The radii of several Ap and Am stars have been compared with those of the normal A stars of the main sequence. Though the brighter Ap stars have a little larger radii than the main sequence stars, they may not be much ...
  • Pi gruis - molecular identifications and spectral classification 
    Murty, P. S (D.Reidel Publishing Co.,, 1983-08)
    Identifications of the molecular absorption features in the visible spectrum of the S star Pi Gruis are presented. Moderate dispersion spectrum of π/sup1 Gru covering the region 5800-7300 Å, demonstrates the presence of a ...
  • Unidentified molecular features in the red spectrum (5800 to 7300 Å) of PI Gruis 
    Murty, P. S (D.Reidel Publishing Co.,, 1982-11)
    Moderate dispersion (46 Å mm–1 at H) image-tube spectrum (5800–7300 Å) of the S star 1 Gru is found to exhibit several unidentified molecular features, in addition to the well-known bands of the oxides ofs-process elements. ...
  • Visible spectrum of Pi/sup1 Gruis - Identification of new E/sup1 Pi-X/sup1 Sigma/sup+/ and 1 Sigma/sup+ - X/sup1 Sigma/sup+ bands of ZrO 
    Murty, P. S (American Astronomical Society, 1982-09)
    New molecular features identified with the e 1H-X + and ` +-X ` + transitions of ZrO, in the 5840-7210 A spectral region of the S star ` Gru, are presented. The measured band positions are in accord with the laboratory and ...
