  • Temporal behaviour of pressure in solar coronal loops 
    Sasidharan, K; Sreedharan, T. D; Pratap, R; Krishan, V (Springer, 1995-03)
    The temporal evolution of pressure in solar coronal loops is studied using the ideal theory of magnetohydrodynamic turbulence in cylindrical geometry. The velocity and the magnetic fields are expanded in terms of the ...
  • A Turbulent model of the solar granulation 
    Krishan, V (World Scientific Publishing Company, 1995)
    The turbulent nature of the motions on the solar photosphere is being emphasized more and more by the high resolution quality observations. The processes of inverse cascade of energy in a turbulent medium are being ...
  • Two-dimensional pressure structure of a coronal loop 
    Krishan, V (Springer, 1985)
    The steady-state pressure structure of a solar coronal loop is discussed using the theory of magnetohydrodynamical turbulence in cylindrical geometry. The steady state is represented by the superposition of two ...
  • Upper mass limit for neutron star stability against black hole formation 
    Krishan, V; Kumar, N (D.Reidel Publishing Co.,, 1978-08)
    Starting from the exact general relativistic expression for the total energy of selfgravitating spherically distributed matter and using the minimum energy principle, we calculate the upper mass limit for a neutron star ...
  • Vlasov-Maxwell equilibria of solar coronal loops 
    Krishan, V; Sreedharan, T. D; Mahajan, Swadesh M (Royal Astronomical Society, 1991-04)
    A Vlasov-Maxwell description of the ubiquitous solar coronal structures is presented. It is found that an equilibrium plasma configuration can live with spatial gradients in density, temperature, current and drift speeds ...
  • Waves in the solar photosphere 
    Pandey, B. P; Vranjes, J; Krishan, V (Blackwell Synergy, 2008-05)
    The solar photosphere is a partially ionized medium with collisions between electrons, various metallic ions and neutral hydrogen playing an important role in the momentum and energy transport in the medium. Furthermore, ...
  • WKB Analysis of Axisymmetric Magneto-Rotational Instability in a Thin Accretion Disk 
    Furukawa, M; Krishan, V; Hirota, M; Yoshida, Z (The Japan Society of Plasma Science and Nuclear Fusion Research, 2006)
    The temporal behavior of axisymmetric magneto-rotational instability in a thin accretion disk is analyzed via the Wentzel-Kramars-Brillouin (WKB) method. The height of the thin disk is used as a small parameter. It is found ...
