  • HR3040- on the Am track ? 
    Sreedhar Rao, S; Raghavender Rao, C; Kilambi, G. C (Astronomical Society of India, 1999)
    HR 3040 (HD 63589) exhibits pseudo-luminosity effects similar to many a main-sequence Am star, especially a strong Sr II 4077 line indicating a higher luminosity class. Its K-line matches that of A3 V, violet and blue ...
  • Mid-ultraviolet and optical photometry of helium stars 
    Kilambi, G. C; Nagar, P; Kameswara Rao, N (Indian Academy of Sciences, 1992-06)
    Mid-ultraviolet and optical photometric analysis of helium stars are presented. A linear relation exists between the effective temperature derived from model atmospheres and (1965-V)0 index. The effective temperatures ...
  • Near infrared photometry of the young open cluster NGC 1960 
    Hasan, P; Kilambi, G. C; Baliyan, K. S (Astronomical Society of India, 2002-09)
    We present the preliminary results of observations of NGC 1960 which was observed from the Mt Abu Infrared Observatory, using the NICMOS3 infrared array mounted on the 1.2 m Cassegrain focus telescope. The observations ...
  • Near Infrared Photometry of the Young Star Cluster NGC 2384 
    Hasan, P; Kilambi, G. C; Baliyan, K. S (Astronomical Society of India, 2003)
    This work involves near infrared photometry of the young cluster NGC 2384. Observations were taken at the Mt Abu Infrared Observatory using the NIC-MOS3 detector in February 2000. The distance to the cluster is obtained ...
  • Near IR study of the young cluster NGC 2453 
    Hasan, P; Kilambi, G. C; Baliyan, K. S (Astronomical Society of India, 2001)
    In an attempt to understand early phases of stellar evolution and star formation, we have taken up the study of extremely young star clusters in the near infrared wavebands. These clusters are deeply embedded inside the ...
  • New probable members of a galactic cluster in the direction of the Large Magellanic Cloud 
    Kilambi, G. C (Astronomical Society of India, 1982-06)
    A BV photographic photometric analysis has established magnitudes and colours for an additional 20 stars in the vicinity of Anon. Bok group. Of these, five are new probable members of the group. An age of 500 Myr is derived ...
  • Photographic astrometry of Comet Halley 
    Ballabh, G. M; Kilambi, G. C; Sanwal, N. B; Sreedhar Rao, S; Swaminathan, R; Raghavender Rao, C (Astronomical Society of Indian, 1989-12)
    The 20-cm astrograph of the Nizamiah and Japal-Rangapur Observatoies in India was used to obtain photographic plates of Comet Halley before and after perihelion during the 1985-1986 apparition. The images are reduced and ...
  • Preliminary study of the Old open Cluster NGC 6192 
    Kilambi, G. C; FitzGerald, M. P (Astronomical Society of India, 1983-09)
    NGC 6192 is an old open cluster (of 6`.8 radius) with turn-off at about Mv = 2.2, corresponding to an age of 9 X 10/sup8/ yr. It has a mean colour excess of 0.26 plus or minus 0.08 (s.d., 11 stars) and a distance of 890 ...
  • Young Galactic Clusters 
    Kilambi, G. C (Astronomical Society of India, 1983-12)
    The evolutionary nature of the young galactic clusters, from both observational as well as theoretical points of view, is briefly discussed. In addition, some of the interesting properties of the individual objects associated ...
