  • CO in the IUE spectrum of Comet Bradfield (1979l) 
    Murty, P. S (D.Reidel Publishing Co.,, 1982-02)
    New identifications are reported of the fourth positive bands and Cameron bands of CO in the IUE satellite spectrum of Comet Bradfield (1979l). Although the predicted band intensities as well as the band identifications ...
  • Cool star flux spectra for population studies in galaxies 
    Malagnini, M. L; Morossi, C; Buser, R; Parthasarathy, M (EDP Sciences, 1992-08)
    Five solar-composition cool giant stars have been observed with the IUE low resolution mode. The UV energy distributions were merged with visual spectrophotometry from the literature and compared with predictions from two ...
  • Epsilon Aurigae in eclipse. I - Ultraviolet spectroscopy during INGRESS and totality 
    Parthasarathy, M; Lambert, D. L (Astronomical Society of the Pacific, 1983-12)
    Epsilon Aurigae is a long-period eclipsing system containing a F0 Ia supergiant and an unseen slightly less-massive secondary. A primary eclipse began in mid-1982 with the unseen companion passing in front of the supergiant. ...
  • IUE observations of high galactic latitude F supergiants HD 161796 and HD 187885 
    Parthasarathy, M; Pottasch, S. R; Wamsteker, W (European Southern Observatory, 1988-09)
    Low resolution (6 A) IUE ultraviolet spectra of the high galactic latitude F supergiants HD 161796 (F3 Ib) and HD 187885 (F2-3I) are analyzed. The UV spectrum (1250 A to 3250 A) of HD 161796 shows no excess UV flux ...
  • The IUE ultraviolet spectrum of PC 11 
    Parthasarathy, M; Pottasch, S. R; Clavel, J (International Astronomical Union, 1993)
  • MG II emission of Pop. 2 long-period Cepheids 
    Parthasarathy, M; Parsons, S. B (1984-12)
    The Population II Cepheid pulsational variables AL Vir (P = 10.3 days) and W Vir (P = 17.3 days) were observed with IUE at two phases each. Only low-dispersion mid-UV exposures were feasible, but were sufficient to show a ...
  • Observations of hydrogen deficient binary Upsilon Sagittarii 
    Kameswara Rao, N; Venugopal, V. R (Indian Academy of Sciences, 1985-06)
    The absolute magnitude M(v) of the hydrogen deficient binary Upsilon Sgr has been estimated as -4.8 + or - 1.0 from the distribution of the interstellar reddening, polarization, and interstellar lines of the surrounding ...
  • Spectroscopic studies of R CrB during light minima - Absorption spectrum 
    Kameswara Rao, N; Giridhar, S; Ashoka, B. N (Royal Astronomical Society, 1990-05)
    R CrB was observed during the 1986 shallow minimum to study the spectral changes taking place during light minimum as compared with the spectrum at maximum light. The absorption spectrum at this minimum is very similar to ...
