Magnetic reconnection driven by a synthetic photospheric velocity field

摘要: We present a dynamic model of atmospheric magnetic field in which loop footpoints are advected by velocity computed using simple n-body simula- tion and reproducing large spatial organization scales (e.g. mesogranulation). In this model, the advection passive elements triggers multiple reconnection processes forc- ing reconfigurations ensuing fluctuations total energy. The simulations reproduce system with scale-free properties, provides frequency distribution functions for emitted energies, described power-law index 2:4, also quiescent times between di erent energy emissions.
