  • A multiwavelength study of LS II+34 26: a hot post-AGB star in the process of becoming a planetary nebula 
    Garcia-Lario, P; Parthasarathy, M; de Martino, D; Sanz Fernandez de Cordoba, L; Monier, R; Manchado, A; Pottasch, S. R (European Southern Observatory, 1997-10)
    We present the results from a multiwavelength analysis of LS II+34 26, recently identified as a low mass post-AGB star and not a massive population I B-type star, as previously thought. We confirm that the central star is ...
  • SAO 244567 - A post-AGB star which has turned into a planetary nebula within the last 40 years 
    Parthasarathy, M; Garcia-Lario, P; Pottasch, S. R; Manchando, A; Clavel, J; de Martino, D; Van de Steene, G. C. M; Sahu, K. C (European Sothern Observatory, 1993-01)
    SAO 244567 (Hen 1357 = CPD -59 deg 6926 = IRAS 17119-5926) is an IRAS source with far infrared colors and flux distribution similar to those of planetary nebulae. The IUE ultraviolet spectra obtained in July 1988 and April ...
  • 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 ...
