Numerical Simulations of Solar Flares

Particle acceleration in solar flares: observations versus numerical simulations

Solar flares are generally agreed to be impulsive releases of magnetic energy. Reconnection in dilute plasma is the suggested trigger for the coronal phenomenon. It releases up to 1026 J, accelerates up to 1038 electrons and ions and must involve a volume that greatly exceeds the current sheet dimension. The Ramaty High-Energy Solar Spectroscopic Imager satellite can image a source in the coron...

Numerical Study of Magnetic Reconnection Processes in Solar Flares

Preface W. F. Ames (1965) said " fluid mechanics is especially rich in nonlinearities ". In this sense, I might as well say " Magnetohydrodynamics (MHD) is much richer ". Such rich nonlinearities bring about not only infinite research interest, but also enormous difficulty in mathematically treating them. Numerical simulation provides a powerful approach to overcome the difficulty and to invest...

Numerical Simulations of Magnetized Winds of Solar-Like Stars

We investigate magnetized solar-like stellar winds by means of self-consistent threedimensional (3D) magnetohydrodynamics (MHD) numerical simulations. We analyze winds with different magnetic field intensities and densities as to explore the dependence on the plasma-β parameter. By solving the fully ideal 3D MHD equations, we show that the plasma-β parameter is the crucial parameter in the conf...
