  • Solar forcing on the changing climate 
    Hiremath, K. M (Balkan, Black Sea and Caspian Sea, 2009-04)
    The influence of solar cycle and activity phenomena on the two climatic variabilities such as the rainfall and the surface temperature of the Indian subcontinent is critically examined. It is concluded from this study that ...
  • Solar wind associated with near equatorial coronal Hole 
    Hegde, M; Hiremath, K. M; Doddamani, V. H; Gurumath, S. R (2015-09)
    Present study probes temporal changes in the area and radiative flux of near equatorial coronal hole associated with solar wind parameters such as wind speed, density, magnetic field and temperature. Using high temporal ...
  • Steady and fluctuating parts of sun's internal magnetic field 
    Gokhale, M. H; Hiremath, K. M (International Astronomical Union, 1993-01)
    We have modeled the 'steady' part of sun's internal poloidal magnetic field in the form of a central dipole and a central hexapole with strengths (0.6 +/- 0.1)B(o)R(0) exp 3 and (0.16 +/- 0.05)B(o)R(0) exp 5 embedded in ...
  • Steady part of rotation and toroidal component of magnetic field in the solar convective envelope 
    Hiremath, K. M (Astronomical Society of India, 2001)
    With reasonable assumptions and approximations, we solve analytically the full set of Chandrasekhar's (1956) MHD equations in the convective envelope, for steady part of rotation and toroidal component of the magnetic field ...
  • Steady part of the sun's internal rotation 
    Hiremath, K. M; Gokhale, M. H (Astronomical Society of India, 1998)
    It is shown that steady part of rotation in the Sun's convective envelope (CE) and radiative core (RC)can be determined as an analytical solution of the diffusion equation in an incompressible medium of constant diffusivity. ...
  • Steady parts of rotation and magnetic field in the sun's convective envelope 
    Hiremath, K. M; Gokhale, M. H (Astronomical Society of India, 1996)
    We use the full set of Chandrasekhar's (1956) MHD equations for determining the steady parts of rotation and poloidal as well as toroidal magnetic field, in the Sun's convective envelope assuming incompressibility. The ...
  • "Steady" and "Fluctuating" Parts of the Sun's Internal Magnetic Field: Improved Model 
    Hiremath, K. M; Gokhale, M. H (The American Astronomical Society, 1995-07)
    Using reasonable assumptions and approximations it is shown that the poloidal component part of the magnetic field in the Sun's radiative core (RC) and convection zone (CE) can be modeled as in an analytical solution of ...
  • Study of Sun's "hydromagnetic" Oscillations Using Sunspot Data 
    Gokhale, M. H; Javaraiah, J; Hiremath, K. M (International Astronomical Union, 1990)
    Spherical-harmonic-fourier (SHF) analysis of sun’s ‘nominal toroidal magnetic field’, computed using sunspot data during 1874-1976, shows that sunspot activity can be considered as possibly originating in interference of ...
  • Study of Sun's Long Period Oscillations 
    Hiremath, K. M (Indian Institute of Astrophysics, Bangalore, 1994-07)
  • The thermal structure of sunspots 
    Hiremath, K. M; Akshatha, B. B (Springer, 2010)
    We use SOHO/MDI continuum images to measure the average thermal structure of bipolar spots during their initial appearance. Although the average thermal structure of penumbrae is independent of sunspot size and life span, ...
  • Toroidal magnetic field structure of the solar convective envelope inferred from the initial observations of the sunspots 
    Hiremath, K. M; Lovely, M. R (Elsevier B.V., 2012-05)
    For different life spans, we measure the line of sight component of the magnetic field structure of the bipolar sunspots from the SOHO/MDI magnetograms during their initial appearance on the surface and toroidal component ...
  • Torsional MHD Oscillations of the Sun 
    Hiremath, K. M; Gokhale, M. H (The Korean Astronomical Society, 1996-12)
    Assuming that the solar activity and the solar cycle phenomena may be manifestations of global torsional MHD oscillations, we compute the Alfven wave travel times along the field lines in the five models of magnetic field ...
  • Variations in the rotational velocity of sunspot groups during their lifetimes. 
    Gokhale, M. H; Hiremath, K. M (Astronomical Society of India, 1984-12)
