  • The chemical composition of the RV Tauri variable IW Carinae 
    Giridhar, S; Kameswara Rao, N; Lambert, D. L (The American Astronomical Society, 1994-12)
    Analysis of the RV Tauri star IW Carinae shows a photospheric composition unlike that reported previously for a few other RV Tau stars but resembling that of certain post-asymptotic giant branch stars (post-AGB) stars. IW ...
  • A compilation of physical parameters of AP and AM stars as derived from energy distribution studies 
    Babu, G. S. D; Shylaja, B. S (Kluwer Academic Publishers, 1981-09)
    The physical parameters, such as the effective temperatures, radii, bolometric magnitudes and bolometric corrections of 87 Ap and Am stars out of the 125 compiled here are essentially based on the work done by the authors ...
  • 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, ...
  • Identification of infrared sources in the IRAS circulars 
    Seal, P (Kluwer Academic Publishers, 1985-07)
    From IRAS (Infrared Astronomical Satellite) Circulars Nos. 4 to 15, 110 infrared sources have been identified. Out of these 110 identified sources 99 are galaxies, nine are nebulae, one is a dark object, and one is a ...
  • Mutual phenomena of the Galilean satellites: an analysis of the 1991 observations from VBO 
    Vasundhara, R (European Southern Observatory, 1994-01)
    Results of analysis of seventeen mutual events, of the Galilean satellites, observed at the Vainu Bappu Observatory (VBO) during the 1991 are presented. The light curves were fitted with theoretical models to derive the ...
  • The R Coronae Borealis stars - A few mere facts 
    Lambert, D. L; Kameswara Rao, N (Indian Academy of Sciences, 1994-03)
    This review presents a selection of recent highlights of observations of R Coronae Borealis (RCB) variables. Emphasis is placed on an abundance analysis of a complete sample (18 stars) of the warm galactic RCBs. It is shown ...
  • Rapid variations of H-alpha emission strength of eight Be stars 
    Ghosh, K. K (Kluwer Academic Publishers, 1988-08)
    Rapid observations of H profiles of eight Be stars have been obtained and it is found that rapid (in a time-scale of 4 to 6 minutes) and irregular variations of total emission strength of H line are present in these stars. ...
  • VLA observations of extreme hydrogen deficient stars 
    Kameswara Rao, N; Venugopal, V. R; Patnaik, A (Indian Academy of Sciences, 1985-09)
    Observations at 2 and 6 cm have been obtained for six hydrogen-deficient stars R CrB, HD 160641, BD -9 deg 4395, V 348 Sgr, MV Sgr, and Upsilon Sgr by means of the National Radio Astronomy Observatory's Very Large Array ...
