Exploring Solar Flares with Gamma Rays and Neutrons
Gamma-ray and neutron emissions from solar flares carry information about the flaring process and conditions within the flaring magnetic loop. Extraction of this information from solar flare measurements requires an ionacceleration, transport, and interaction model with parameters directly related to those physical processes. In this paper we describe such a magnetic-loop model. Each of the gam...
متن کاملAstrophysical explosions: from solar flares to cosmic gamma-ray bursts
Astrophysical explosions result from the release of magnetic, gravitational or thermonuclear energy on dynamical time scales, typically the sound-crossing time for the system. These explosions include solar and stellar flares, eruptive phenomena in accretion discs, thermonuclear combustion on the surfaces of white dwarfs and neutron stars, violent magnetic reconnection in neutron stars, thermon...

متن کاملLithium-6 from Solar Flares
By introducing a hitherto ignored Li producing process, due to accelerated He reactions with He, we show that accelerated particle interactions in solar flares produce much more Li than Li. By normalizing our calculations to gamma-ray data we demonstrate that the Li produced in solar flares, combined with photospheric Li, can account for the recently determined solar wind lithium isotopic ratio...
متن کاملGamma-Ray Polarimetry of Two X-Class Solar Flares
We have performed the first polarimetry of solar flare emission at γ-ray energies (0.2–1MeV). These observations were performed with the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) for two large flares: the GOES X4.8-class solar flare of 2002 July 23, and the X17-class flare of 2003 October 28. We have marginal polarization detections in both flares, at levels of 21 ± 9% and -...
