  • Low-resolution spectroscopy of high galactic latitude objects: a search for CH stars 
    Goswami, A; Bama, P; Shantikumar, N. S; Devassy, D (Astronomical Society of India, 2007-09)
    Properties of CH stars like iron deficiency and enrichment of carbon and heavy elements can provide valuable inputs to our understanding of nucleosynthesis. In particular, these parameters provide strong observational ...
  • Nebular emission lines in IRAS 10215-5916 
    Garcia-Lario, P; Manchado, A; Parthasarathy, M; Pottasch, S. R (European Southern Observatory, 1994-05)
    From low and high resolution spectroscopic observations of IRAS 10215-5916 we have discovered the presence of nebular emission lines in this G-type supergiant star in the post-AGB stage. From its high resolution spectrum ...
  • Spectral classification of unidentified IRAS sources with F{_nu }(12 μm) >= F{_nu }(25 μm) 
    Iyengar, K. V. K; MacConnell, D. J (The European Southern Observatory, 1998-12)
    Spectral types of a large number of unidentified IRAS Point Sources with F{_nu }(12 μm) >= F{_nu }(25 μm) were determined; the majority are faint, oxygen-rich (M-type) or carbon-rich giant stars. The Guide Star Catalog has ...
