Propagation of Type II spicules into the solar corona III. MHD simulation

Abstract

Abstract We study the possible influence of a magnetic narrow region on the propagation of jets with some characteristics of Type II spicules into the solar corona using MHD approximation numerical simulations. We found that an increase of temperature occurs mainly at the top of the jet, which supports the idea of sectioning the spicule in the TM approximation of the previous works. Also, we show that the magnetic bottle does not directly affect the propagation of the jet; since the physical conditions of the ideal MHD equations imply that the magnetic field lines are frozen-in with the plasma.
