Solar Gamma-Ray Physics Comes of Age

Abstract

The launch of NASA s HESSI satellite will provide solar scientists with 2arcsec imaging/ 2 keV spectroscopy of solar flares from ~10 keV to 10 MeV for the first time. We summarize recent developments in our understanding of solar flares based primarily on gammaray line measurements made over the past twenty years with instruments having moderate spectral resolution. These measurements have provided information on solar ambient abundance, density and temperature; accelerated particle composition, spectra, and transport; and flare energetics.
