Solar Flares, Magnetic Reconnection
Scientific paper
We studied Bastille Day flare, famous and big solar flare on 14 Jul. 2000. This phenomenon is important to learn about the physical relationship between solar intensities and magnetic field distributions. The considered time evolutions of this large "Two-ribbons" class flare and its characteristic of magnetic reconnection structure are the principle aim of this work. We have used the simulation program and Image Processing method to consider different physical quantities like VA, Alfvenic speed, β = Pg/Pm, where Pg denotes the gas pressure and Pm magnetic pressure of the plasmas inside the current sheet after occurrence of magnetic reconnection process. We have used Trace Observations Data as needed processing images. Construction of the time evolution images in interval of ~10 min. (occurrene of flare phenomena) was used as an original data for applying the simulation method. Magnetic reconnection simulation program K. Shibata (Shibata et al. 1989) is used to study the fitting of theoretical and observational results. In the process, we have obtained the variations of the magnetic energy distribution in terms of thermal and kinetic energy of the plasma (the magnetic energy release rate), inflow and outflow velocities, and magnetic field and intensity.
