  • Scattering of quasar radiation in intercloud plasma 
    Krishan, V (Royal Astronomical Society, 1988-09)
    Three different levels of description are available to describe the interaction of electromagnetic radiation with electrons in a fully ionized plasma: stimulated Raman scattering, stimulated Compton scattering, and Compton ...
  • Second National Workshop on Solar Physics, Indian Institute of Astrophysics, Kodaikanal, India 
    Krishan, V; Sastry, Ch. V (Springer, 1989-09)
    This paper a brief report about the topics discussed at the second Indian national Workshop on Solar Physics held in September 1987
  • Self-organization processes in astrophysics 
    Krishan, V (Indian Association for the Cultivation of Science, 1992)
  • Self-organization processes on the sun - The heliosynergetics 
    Krishan, V; Mogilevskij, E. I (International Astronomical Union, 1990)
    A study by Levich and Tzvetkov (1985) is used to construct a model of solar granulation in its entirety. Solar granulation on all scales and the formation and evolution of some structures in active solar regions are ...
  • Simultaneous Organisation of v, B - the Spicules 
    Krishan, V (International Astronomical Union, 1990)
  • Solar Cycle Phase Dependence of Supergranular Fractal Dimension 
    Paniveni, U; Krishan, V; Singh, J; Srikanth, R (Indian Academy of Sciences, 2011-06)
    We study the complexity of supergranular cells using the intensity patterns obtained from the Kodaikanal Solar Observatory during the 23rd solar cycle. Our data consists of visually identified supergranular cells, from ...
  • Solar physics at Indian Institute of Astrophysics 
    Venkatakrishnan, P; Krishan, V (Indian Institute of Astrophysics, 1989-12)
  • Solar physics in India 
    Krishan, V; Bhattacharyya, J. C (National Solar Observatory, 1988-07)
  • Solar plasma physics 
    Krishan, V (Indian Academy of Sciences, 1991-10)
  • Solar Supergranulation and two-dimensional Hydrodynamic Turbulence 
    Krishan, V (Indian Institute of Astrophysics, Bangalore, 1988)
    In a two-dimensional incompressible fluid, the total energy as well as the total squared vorticity called enstrophy is conserved. It is found that the energy spectrum in two-dimensional hydrodynamic turbulence cascades to ...
  • Spatial profiles of lines in active region loops 
    Krishan, V (Springer, 1983-10)
    From the statistical treatment of magnetohydrodynamically turbulent plasma, a steady-state density, temperature and magnetic field structure is derived for a coronal loop emitting in UV and EUV range. Spatial variation of ...
  • Spectrum of density fluctuations in the solar wind 
    Krishan, V (World Scientific Publishing Company, 2009)
    The power spectrum of density fluctuations in the solar wind and its relations with the spectra of the velocity and magnetic field fluctuations is investigated. The density fluctuations could behave as a passive scalar and ...
  • Statistical mechanics of velocity and magnetic fields in solar active regions 
    Krishan, V (Springer, 1985-02)
    A statistical mechanics of the velocity and magnetic fields is formulated for an active region plasma. The plasma subjected to the conservation laws emerges in a most probable state which is described by an equilibrium ...
  • Stimulated raman scattering in active galactic nuclei 
    Krishan, V; Wiita, P. J (International Astronomical Union, 1986)
    Stimulated Raman Scattering (SRS) processes offer an attractive and efficient method for producing both essentially the entire non-thermal continuum as well as fast electrons in active galactic nuclei (AGN). In this picture, ...
  • Structure of the Solar Corona 
    Krishan, V (Indian Institute of Astrophysics, Bangalore, 1988)
    Solar eclipses established the existence of the outer region of the solar atmosphere, the solar corona, extending to several solar-radii and exhibiting open and closed magnetic field patterns. The density and the temperature ...
  • Structure of turbulence in the solar convection zone 
    Krishan, V (Astronomical Society of India, 1996)
    Based on the inverse cascade of energy in a turbulent medium, a model of the solar granulation, encompassing all spatial scales, has been proposed. The predicted spatial energy distribution tends to agree fairly well with ...
  • Supergranulation and its Activity Dependence 
    Paniveni, U; Krishan, V; Singh, J; Srikanth, R (Cambridge University Press, 2011-08)
    We study the complexity of supergranular cells using the intensity patterns obtained at the Kodaikanal solar observatory during the solar maximum. Our data consists of visually identified supergranular cells, from which a ...

  • Sweet–Parker current slab in a partially ionized plasma 
    Krishan, V (Blackwell Publishing, 2009-12)
    The formation of the Sweet–Parker current sheet, in fact a slab, is studied for a partially ionized plasma. The effects arising from the ion–neutral drag, the ambipolar diffusion, the resistivity resulting from electron–neutral ...
  • 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 ...
