  • Coronal heating by magnetic kink waves 
    Banerjee, D; Dikpati, M; Choudhuri, A. R (Astronomical Society of the Pacific, 1998)
    We show that the magnetic kink waves generated by the motions of the Photospheric footpoints of the coronal flux tubes can supply adequate energy for heating the quiet corona. We model the solar corona as two-layer isothermal ...
  • Energy transport to the solar corona by magnetic kink waves 
    Choudhuri, A. R; Dikpati, M; Banerjee, D (American Astronomical Society, 1993-08-20)
    We show that the magnetic kink waves generated by the motions of photospheric footpoints of the coronal flux tubes can supply adequate energy for heating the quiet corona, provided there are occasional rapid motions of ...
  • The evolutton of the magnetic structure of the solar corona with the solar cycle 
    Dikpati, M; Choudhuri, A. R; Venkatakrishnan, P (Astronomical Society of the Pacific, 1996)
  • On the Large-Scale Diffuse Magnetic Field of the Sun 
    Dikpati, M; Choudhuri, A. R (Springer, 1995-10)
    Although the sunspots migrate towards the equator, the large-scale weak diffuse magnetic fields of the Sun migrate poleward with the solar cycle, the polar field reversing at the time of the sunspot maxima. We apply the ...
  • On the Out of Phase Appearance of Large-Scale Diffuse Magnetic Field of the Sun with Respect to Sunspots 
    Dikpati, M; Choudhuri, A. R (Kluwer Academic Publishers, 1996-03)
    We assume the large-scale diffuse magnetic field of the Sun to originate from the poloidal component of a dynamo operating at the base of the convection zone, whereas the sunspots are due to the toroidal component. The ...
  • The solar dynamo with meridional circulation 
    Choudhuri, A. R; Schuessler, M; Dikpati, M (European Southern Observatory, 1997-03)
    In the mathematical form for the coefficient given in the expression (4) in this paper, the value of the parameters d and d should actually be 0.025R/sub0 instead of as printed. We became aware of this typographical error ...
  • The solar dynamo with meridional circulation. 
    Choudhuri, A. R; Schussler, M; Dikpati, M (1995-11)
    We show that meridional circulation can have a profound influence on dynamo models for the solar cycle. Motivated by the observed tilt angles of sunspot groups we assume that the generation of the poloidal field takes place ...
  • Triggering The Birth of New Cycle’s Sunspots by Solar Tsunami 
    Dikpati, M; McIntosh, S.W; Chatterjee, Subhamoy; Banerjee, D; Yellin-Bergovoy, Ron; Srivastava, A (Springer Nature, 2019-02-14)
    When will a new cycle’s sunspots appear? We demonstrate a novel physical mechanism, namely, that a “solar tsunami” occurring in the Sun’s interior shear-fluid layer can trigger new cycle’s magnetic flux emergence at high ...
