  • Infrared Photometer system for Astronomical Observations 
    Shivanandan, K; Scaria, K. K; Nair, R. M; Rajamohan, R; Sivaraman, K. R (Indian Institute of Astrophysics, Bangalore, 1987)
    An infrared photometer system has been developed for photometry of astronomical sources in the spectral band 1 to 5 microns. The characteristics of the system and preliminary engineering tests using the 1- m optical ...
  • Integrated brightness and colour of Omega Centauri 
    Scaria, K. K (Astronomical Society of India, 1982-12)
    Integrated magnitudes in U, B, V, R and I bands are calculated for the globular cluseter Omega Centauri. The observed radial chaange in the integrated colour of the cluster shows that the cluster core (r<2') is redder in ...
  • Isodensitometry of Omega Centauri and 47 Tucanae 
    Scaria, K. K (Indian Institute of Astrophysics, Bangalore, 1980)
    We present details of procedure on equidensitometry of globular clusters using the Sabattier technique in photography. Equidensitometry of Omega Centauri and 47 Tuc shows that both clusters become more elliptical beyond r ...
  • Mass segregation in globular clusters 
    Scaria, K. K; Bappu, M. K. V (Indian Academy of Sciences, 1981-09)
  • The Near Infrared Spectra of Wolf Rayet Stars 
    Bappu, M. K. V; Ganesh, K. S; Scaria, K. K (Indian Institute of Astrophysics, Bangalore, 1977)
    The near infrared spectra of three Wolf-Rayet stars of the carbon sequence and five of the nitrogen sequence have been studied. Wavelength identifications and intensity scans are presented to show the emission line ...
  • 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 ...
  • Sky conditions for infrared observations at Kavalur 
    Scaria, K. K; Nair, R. M; Sivaraman, K. R (Astronomical Society of India, 1991)
    The extinction coefficients in the J, H, K near-IR bands are presented that were derived for Kavalur during the years 1987, 1988, and 1989. Humidity and temperature observations made at Kavalur during these years are used ...
  • A survey of red stars in the direction of the Large Magellanic Cloud. 2. Some regions around the bar. 
    Bappu, M. K. V; Parthasarathy, M; Scaria, K. K (Indian Institute of Astrophysics, 1978)
    We have continued the survey for red stars in the direction of the large Magellanic Cloud using the technique of ultra-low dispersion spectroscopy. This paper which is the second one on the series lists 706 stars located ...
  • A Survey of Red Stars in the Direction of the Large Magellanic Cloud. III. Some Regions North of Bar 
    Bappu, M. K. V; Parthasarathy, M; Scaria, K. K (Indian Institute of Astrophysics, Bangalore, 1985-11)
    We have continued the survey for red stars in the direction of the Large Magellanic Cloud using the technique of ultra-low dispersion spectroscopy. In this paper we list 310 red stars located north of L M C bar. Finding ...
  • A Survey of Red Stars in the Direction of the Large Magellanic Cloud: The 30 Doradus Region 
    Bappu, M. K. V; Parthasarathy, M; Scaria, K. K (Indian Institute of Astrophysics, Bangalore, 1977)
    We have commenced a survey of red stars in the direction of the Large Magellanic Cloud using the technique of ultra-low dispersion spectroscopy. This first paper is a listing of the red stars in the 30 Doradus region for ...
