  • The strange case of SN 2011ja and its host 
    Chakraborti, S; Ray, A; Smith, R; Ryder, S; Yadav, N; Sutaria, F. K; Dwarkadas, V. V; Chandra, P; Pooley, D; Roy, R (Cambridge University Press, 2014-01)
    SN 2001ja was observed twice in three months using the Chandra X-Ray Observatory. The X-ray flux could be due to interaction with the circumstellar medium, perhaps dominated by the reverse shock heated thermal plasma, or ...

  • Strengths and weaknesses of the big bang cosmology 
    Narlikar, J. V (Astronomical Society of India, 1992)
    The achievements and shortcomings of the standard hot big bang models of the universe are reviewed. The achievements lie in the predictions of the expanding universe, the abundances of light nuclei, and the MW background. ...
  • String tension and fundamental constants in the early universe 
    Sivaram, C (Springer, 1990-05)

  • Strong Gravity Approach to QCD and Confinement 
    Salam, A; Sivaram, C (World Scientific Publishing, 1993-02)
    A Weyl type of action which is scale free and quadratic in the curvature is suggested for strong gravity. The corresponding field equations have solutions which imply confinement. At the QCD scale, the scale invariance is ...
  • Strong gravity as the connecting link underlying universal relations between angular momenta of celestial bodies and spin of elementary particles 
    de Sabbata, V; Sivaram, C (Springer, 1988-12)
    Empirical relations between the angular momenta of a wide range of celestial bodies as well as relations between masses and spins of hadrons are shown to have the same fundamental basis with strong gravity as the underlying ...
  • Strong gravity, black holes, and hadrons 
    Sivaram, C; Sinha, K. P (American Physical Society, 1977-09)
    Certain similarities and analogies between the properties of black holes and elementary particles are considered in the framework of the strong gravitational field. Properties examined include measurable parameters (mass, ...

  • Strong nonlocality variations in a spherical mean-field dynamo 
    Brandenburg, Axel; Chatterjee, Piyali (WILEY-VCH Verlag GmbH & Co., 2018-02)
    To explain the large-scale magnetic field of the sun and other bodies, the mean-field dynamo theory is commonly applied, where one solves the averaged equations for the mean magnetic field. However, the standard approach ...
  • Strong spin-torsion interaction between spinning protons 
    de Sabbata, V; Sivaram, C (Italian Physical Society, 1989-02)

  • Strong-CP question in SU(3)c×SU(3)L×U(1)N models 
    Palash, B. Pal (The American Physical Society, 1995-08)
    We analyze two recent models based on the gauge group SU(3)c×SU(3)L×U(1)N where each generation is not anomaly-free but the anomaly cancels when three generations are taken into account. We show that the most general Yukawa ...
  • Structural analysis of star-forming blue early-type galaxies Merger-driven star formation in elliptical galaxies

  • Structure and Dynamics of the Solar Wind 
    Vats, Hari Om (Indian Institute of Astrophysics, Bangalore, 1986)
