  Article:   THE OSCILLATION MODES INDUCED BY SPECIAL DRIVERS IN SOLAR CORONAL LOOPS.

Authors:  A. MARCU.
 
       
         
  Abstract:   In this paper we perform a numerical study of transversal oscillations in coronal loops represented as a straight thin flux tube, which are generated under the effect of an external force, the global coronal EIT wave. Given the equation that describes the transversal oscillations in coronal loops, we consider several forms for the driver (e.g. wave train, interaction points separated by a delay time, non-harmonic), and then solve it numerically. We discuss the dependence between the induced oscillation modes and the nature of the driver and its parameters.

Keywords: magnetohydrodynamics (MHD) simulations, EIT waves, coronal loops
