  • Spectroscopy of post-AGB a-supergiant HD 101584 (IRAS 11385-5517) 
    Sivarani, T; Parthasarathy, M; García, L. P; Manchado, A; Pottasch, S. R (Kluwer Academic Publishers, 2001-08)
    In the high resolution optical spectra we identified forbidden lines of [OI] and [CI], which indicate the presence of low excitation nebula. There are many emission lines due forbidden and permitted lines of neutral and ...
  • Spectroscopy of the post-AGB star HD 101584 (IRAS 11385-5517) 
    Sivarani, T; Parthasarathy, M; García-Lario, P; Manchado, A; Pottasch, S. R (The European Southern Observatory, 1999-06)
    From an analysis of the spectrum (4000 Ä to 8800 Ä) of HD 101584 it is found that most of the neutral and single ionized metallic lines are in emission. The forbidden emission lines of [OI] 6300 Ä and 6363 Ä and [CI] 8727 ...
  • The UV (IUE) spectrum of the planetary nebula PC 11 (HD 149427) 
    Parthasarathy, M; García-Lario, P; Pottasch, S. R; de Martino, D; Surendiranath, R (European Southern Observatory, 2000-03)
    The UV spectrum of PC 11 is found to show variations in the strength of the O III] 1666Å , N III] 1750Å and C III] 1909Å emission lines. The detection of continuum emission in the wavelength interval 2650Å to 3200Å indicates ...
