  • Brightness, polarization and electron density of the solar corona of 1980 February 16 
    Sivaraman, K. R; Jayachandran, M; Scaria, K. K; Babu, G. S. D; Bagare, S. P; Jayarajan, A. P (Indian Academy of Sciences, 1984-06)
    During the eclipse of 1980 February 16 the authors photographed the solar corona at an effective wavelength of 6300 Å. Using a quadruple camera coronal pictures were obtained in polarized light for four polaroid orientations. ...
  • Broad-band, high-resolution photograph of the solar corona February 16, 1980 
    Scaria, K. K (Springer, 1983-06)
    Unsharp masking may be used for better reproduction of over-exposed solar corona photographs.
  • Embedded clusters in giant extragalactic H II regions, 1: BVRH-alpha photometry 
    Mayya, Y. D (The American Astronomical Society, 1994-10)
    Photometry in BVR continuum bands and in the emission line of H-alpha+(N II) are presented for a sample of H II complexes in disk, spiral arm and nuclear regions of galaxies NGC 1365, 1566, 2366, 2903, 2997, 3351, 4303, ...
  • Nucleus of NGC 2903 
    Prabhu, T. P (D.Reidel Publishing Co.,, 1980-04)
    The nucleus of NGC 2903 is identified on near infrared photographs. The energy distribution of this nucleus in the visual region of the spectrum is estimated from available observations. The continuum compares well with ...
  • A possible P-L relation for RR-Lyrae variables in globular clusters 
    Scaria, K. K (Kluwer Academic Publishers, 1984-08)
    A study of the mean photographic magnitudes of RR Lyrae variables in galactic globular clusters has shown that the luminosity of RR-ab variables decreases with period. It is found that RR-ab variables, in the cluster ω ...
  • A study of the open cluster NGC 2374 
    Babu, G. S. D (Indian Academy of Sciences, 1985-03)
    The results of modified objective grating observations and photoelectric as well as photographic photometry of the open cluster NGC 2374 are presented. The cluster contains at least twenty stars as definite members down ...
