Spatial Scaling Law in Solar Flares
Abstract
How do the observed macroscopic scales observed in solar flares relate to the theoretically implied microscopic scales of energy release and particle acceleration processes. We approach this question by investigating the fast milli-second time scales observed during the impulsive flare phase in hard X-ray and radio wavelengths and their relation to the spatial scales observed in hard and soft X-ray images. Previous studies with Yohkoh and CGRO data established a scaling law between the temporal and spatial scales. We investigate also the fractal spatial patterns of flares observed at arc-second spatial resolution with TRACE and deduce the fractal dimension in 2D and filling factors in 3D. We discuss the implications of these observational results for the spatial scaling of the underlying magnetic reconnection processes.
