Radio and Hard X-Ray Observations of Flares and their Physical Interpretation'', (Invited Review) View all abstracts by submitter

Markus J Aschwanden   Submitted: 1999-10-06 21:04

        Interpretation'', (Invited Review)We review a selection of observations in radio, hard X-rays (HXR) and soft X-rays (SXR) that constrain geometrical and physical requirements for solar flare models. Guided by observations of interacting flare loops we discuss a flare model based on shear-driven quadrupolar reconnection, which explains single-loop and double-loop flares in a unified picture. We interpret various observational findings in the light of this unified flare model: {- topology and geometry of interacting flare loops, } {- localization of particle acceleration region, } {- scale invariance of electron time-of-flight path and flare loop geometry, } {- density and magnetic field diagnostic in accelerati- acceleration region, } {- bi-directionality of injected electron beams, } {- electron beam trajectories and correlated HXR pulses, } {- bifurcation of directly-precipitating and trap-precipitating electrons, } {- density and magnetic field diagnostic of trap region, } {- elementary time scales and dynamics in acceleration region. }         on
