  • Giridhar, S (Indian Academy of Sciences, 1983-06)
    The determinations are made in order to study the large-scale chemical inhomogeneities across the galactic disk. High-dispersion spectra are obtained of WZ Sgr, X Sgr, Zeta Gem, T Mon and SV Mon. The atmospheric abundances ...
  • Bhatt, H. C; Mallik, D. C. V (The European Southern Observatory, 1986-11)
    Cn 1-1 is an emission-line object that shows strong emission lines characteristic of high density planetary nebulae superposed on the stellar spectrum of an F5 III-IV star. The authors estimate the absolute luminosity of ...
  • Ferro, A. A; Parrao, L; Giridhar, S (Astronomical Society of the Pacific, 1988-08)
    UBVRI and uvby photometry and radial velocities have been obtained for the F0 Ia supergiant Phi Cas. The variability is confirmed from the radial velocities; the velocity range is small (Delta V/subr of about 6 km/s). No ...
  • Pottasch, S. R; Parthasarathy, M (European Southern Observatory, 1988-03)
    The far-infrared IRAS excesses are found in ten luminous F-G stars. The far-IR fluxes from these stars are due to large amounts of dust around them. The far-IR flux distribution, far-IR luminosities and dust masses are ...
  • Arellano Ferro, A; Giridhar, S; Goswami, A (Royal Astronomical Society, 1991-05)
    High-resolution CCD data and a large group of F-G stars of fundamentally determined distances are used here to investigate the intrinsic nature of the M(v) - W(O I) relation and the effect of other atmospheric parameters ...
