Electron-heated flare models - alive and well

The idea that deka-keV electrons, accelerated during the primary energy release, are responsible for the bulk of the impulsive phase energy transport in solar flare atmospheres has been around for quite some time now. With the advent of (i) detailed numerical calculations of the hydrodynamic response of the atmosphere to the energy input from such electrons, and (ii) the observations made during the last solar maximum of the spatial, spectral, and temporal behavior of flare-associated emissions in a variety of wavelength ranges, we have now reached a point where quantitative tests of the thick-target electron-heated model (Brown, 1973) are possible. Here I describe some recent results of such quantitative tests.
