Low-Energy Cutoffs and In Electron Spectra Of Solar Flares: Statistical Survey
The Ramaty High Energy Solar Spectroscopic Imager (RHESSI) Xray data base (February 2002 – May 2006) has been searched to find solar flares with weak thermal components and flat photon spectra. Using a regularised inversion technique, we determine the mean electron flux distribution from count spectra of a selection of events with flat photon spectra in the 15–20 keV energy range. Such spectral...

متن کاملElectron-Electron Bremsstrahlung Emission and the Inference of Electron Flux Spectra in Solar Flares
Although both electron-ion and electron-electron bremsstrahlung contribute to the hard Xray emission from solar flares, the latter is normally ignored. Such an omission is not justified at electron (and photon) energies above ∼ 300 keV, and inclusion of the additional electron-electron bremsstrahlung in general makes the electron spectrum required to produce a given hard X-ray spectrum steeper ...
متن کاملEvolution of electron energy spectrum during solar flares
Particle acceleration by direct-current electric field in the current sheet has been extensively studied, in which an electric and a magnetic field are generally prescribed, and a power law distribution of the electron energy is obtained. Based on MHD numerical simulations of flares, this paper aims at investigating the time evolution of the electron energy spectrum during solar flares. It turn...
متن کاملStatistical analysis of solar H α flares
A statistical analysis of a large data set of Hα flares comprising almost 100 000 single events that occurred during the period January 1975 to December 1999 is presented. We analyzed the flares evolution steps, i.e. duration, rise times, decay times and event asymmetries. Moreover, these parameters characterizing the temporal behavior of flares, as well as the spatial distribution on the solar...
