  • Torsion and massive electrodynamics in the early universe 
    Sivaram, C; de Andrade, L. C. G (Springer, 1994-06)
    A recent model based on massive electrodynamics in spaces with torsion gave rise to London type equations with Meissner-like effects and photon mass. This effective photon mass can be related to a time-varying torsion ...
  • Strong Gravity and Strings 
    Sivaram, C; de Sabbata, V (Wiley InterScience, 1991)
  • Radiation of the fifth-force field 
    Bertotti, B; Sivaram, C (Springer, 1991-11)
    The «fifth-force» field, if it exists, has radiative effects in competition with the gravitational radiation. Since this field violates the Principle of Equivalence, it may affect a gravitational wave detector more than a ...
  • Abundance gradient in interstellar medium 
    Giridhar, S (Centre of Advanced Study in Astronomy Osmania University, 1984)
    The author discusses in this review the implication of observed abundance gradient in the interstellar medium on the chemical evolution of the galaxy. I describe the ingradients that are required to develop enrichment model ...
  • Abundance analysis of selected Cepheids and the galactic distribution of metallicity 
    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 ...
  • Detection of an extremely active state of AM Canum Venaticorum 
    Kutty, K. R. N; Marar, T. M. K; Padmini, V. N; Seetha, S; Kasturirangan, K; Rao, U. R; Bhattacharyya, J. C; Mohin, S; Jayakumar, K (D. Reidel Publishing Co., 1986)
    We report fast photometric observations of AM Canum Venaticorum (AM CVn), the ultrashort-period, hydrogen-deficient variable, are reported. An intense flare of (Delta m) peak roughly 0.34 was detected on February 24th, ...
  • Minor planets and planetary rings 
    Bhattacharyya, J. C (Centre of Advanced Study in Astronomy Osmania University, 1984)
    Circumstances of the discovery of the first asteroid and the characteristics of various orbits followed by them have been discussed. Their shapes, compositions and evolutionary histories so far known have also been described. ...
  • Astronomy in India in the 20th century. 
    Bhattacharyya, J. C; Vagiswari, A (Indian National Science Academy, 1985)
  • The inconsistency of a model for internal structure or black holes 
    Sivaram, C (Indian Academy of Sciences, 1985-08)
    The recent claim that a black hole can be treated as a relativistic gas of micro black holes (planckions) is shown to be physically inconsistent and in fact is grossly in error. Any deductions made about black holes from ...
  • Mildly Active Nuclei of Galaxies 
    Prabhu, T. P (Indian Academy of Sciences, 1985)
    Milder forms of activity in the nuclear regions of galaxies are reviewed. Three classes of activity are identified, namely starbursts, high-excitation emission-line and low-ionization emission-line nuclei. Sérsic perinuclear ...
  • Limits on surface magnetic fields of fast pulsars 
    Datta, B (Nature Publishing Group, 1984-03-22)
    The rapid rotation rate of millisecond pulsar PSR 1937+214 suggests that it may be close to the point of rotational instability. Rotational stability implies lower limits on the mass and moment of inertia, and an upper ...
  • Science in British India. I. Colonial tool 
    Kochhar, R. K (Indian Academy of Science, 1992-12-10)
  • Polarimetric observations of hydrogen deficient stars 
    Raveendran, A. V; Kameswara Rao, N; Deshpande, M. R; Joshi, U. C; Kulshrestha, A. K (Reidel Publishing Company, 1986)
    Polarimetric observations of HD 30353, SU Tau, XX Cam, R CrB, UV Cas, BD +13°3224, BD +10°2179 and HD 124448 are presented. The linear polarization of HD 30353 is found to vary appreciably at Hα over a time scale as short ...
  • HD 22403: a New Variable with Ca II H and K Emission 
    Raveendran, A. V; Mohin, S; Mekkaden, M. V (Konkoly Observatory, 1985-03-26)
  • General relativistic effects on the pulse profile of fast pulsars 
    Datta, B; Kapoor, R. C (Nature Publishing Group, 1985-06-13)
    The recent discovery of millisecond pulsars has led to several theories about the structure and radiation characteristics of rapidly rotating neutron stars. The rapid rotation rate implies that such pulsars will be compact ...
  • Birthrate of Planetary Nebulae 
    Mallik, D. C. V (International Astronomical Union, 1983)
    The electron density, temperature and ion abundances in the nebulae surrounding the two WC 10 stars CPD-56 deg 8032 and He2-113 have been estimated. In CPD-56 deg 8032 sulphur, nitrogen and oxygen seem to have solar ...
  • Photometric Variability of HD 81410 in 1988 
    Mekkaden, M. V; Sinachopoulos, D (Konkoly Observatory, 1988-08-15)
  • Dramatic Changes in the Polarization of AR Pup 
    Raveendran, A. V; Deshpande, M. R; Kameswara Rao, N; Joshi, U. C; Kuleshrestha, A. K (Konkoly Observatory, 1985-04-25)
  • 1986 Light Curve of V711 Tau 
    Mekkaden, M. V (Konkoly Observatory, 1987-07-03)
  • Reflection effect in close binaries 
    Peraiah, A (Centre of Advanced Study in Astronomy Osmania University, 1984)
    The author describes an initial attempt of how the radiation field is calculated from the irradiated surface of the component in a binary system.
