[ 1 ] - Generation of Alfvén Waves by Small-Scale Magnetic Reconnection in Solar Spicules
Alfvén waves dissipation is an extensively studied mechanism for the coronal heating problem. These waves can be generated by magnetic reconnection and propagated along the reconnected field lines. Here, we study the generation of Alfvén waves at the presence of both steady flow and sheared magnetic field in the longitudinally density stratified of solar spicules. The initial flow is assumed to...
[ 2 ] - Study of Solar Magnetic and Gravitational Energies Through the Virial Theorem
Virial theorem is important for understanding stellar structures. It produces an interesting connection between magnetic and gravitational energies. Using the general form of the virial theorem including the magnetic field (toroidal magnetic field), we may explain the solar dynamo model in relation to variations of the magnetic and gravitational energies. We emphasize the role of the gravitatio...
[ 3 ] - بررسی اتصال مجدد مغناطیسی غیر خطی در کروموسفر خورشیدی
In order to see the occurrence of magnetic reconnection in the solar chromosphere, we investigate the behavior of non-linear perturbations on the magneto hydro dynamic (MHD) equations. Numericalstudy of the resistive tearing instability in a current sheet is presented by considering the MHD framework.To do this, the four field model is applied. It is shown based on the simulation that the non-l...
[ 4 ] - Damping of visco-resistive Alfven waves in solar spicules
Interaction of Alfven waves with plasma inhomogeneity generates phase mixing which can cause the dissipation of Alfven waves. We investigated the dissipation of standing Alfven waves due to phase mixing at the presence of steady flow and sheared magnetic field in solar spicules. Moreover, the transition region between chromosphere and corona was considered. Our numerical simulation showed that ...
