Professional Standing

Studies of linear and nonlinear resonant MHD wave heating under solar atmospheric conditions.
My major new results are:

  • derivation of the generalised governing equation for resonant slow MHD waves in isotropic and anisotropic steady plasmas;
  • obtaining jump conditions to connect solutions across a resonant layer. These universal connection formulae play a crucial role, similar to the Rankine-Hugoniot relations of nonlinear gas dynamics;
  • proof of the validity of the universal character of the jump conditions in dissipative MHD and in dilute plasmas;
  • making successful applications of resonant MHD wave theory (e.g. sunspots, magnetic canopy, fibrils, coronal loops and magnetosphere);
  • developing the tools of global coronal seismology.
