Numerical simulations of magnetoacoustic?gravity waves in the solar coronal curved magnetic field lines structure View all abstracts by submitter

Petr Jelinek   Submitted: 2013-07-25 00:38

We present a two-dimensional (2D) magnetohydrodynamic (MHD) model of magneto-acoustic?gravity waves in the gravitationally stratified solar corona that is shaped by a realistic (VAL-C, Vernazza Avrett Loeser model C) temperature profile and curved magnetic field lines. These waves are triggered by an initial Gaussian pulse in the horizontal component of velocity, that is, launched either just below or above the transition region. The time-dependent ideal MHD equations are solved numerically with the use of the flash code. The numerical results reveal conversion of a horizontal flow into its vertical counterpart, oscillations of the transition region and vertical jets of cold plasma penetrating the solar corona. The wavelet analysis of the mass-density variations at a fixed detection point leads to the oscillation period of about 180 s, which corresponds to 3-min oscillations observed in solar active regions.
