Compton backscattered and primary X-rays from solar flares: angle dependent Green's function correction for photospheric albedo
Eduard P. Kontar, Alec L. MacKinnon, Richard A. Schwartz +1
The observed hard X-ray (HXR) flux spectrum from solar flares is a combination of primary bremsstrahlung photons with a spectrally modified component from photosphe…
Multi-wavelength analysis of high energy electrons in solar flares: a case study of August 20, 2002 flare
J. Kasparova, M. Karlicky, E. P. Kontar +2
A multi-wavelength spatial and temporal analysis of solar high energy electrons is conducted using the August 20, 2002 flare of an unusually flat (gamma=1.8) hard X-ray spectrum. T…
Solar Flare Hard X-ray Spectra Possibly Inconsistent with the Collisional Thick Target Model
Eduard P. Kontar, John C. Brown
Recent progress in solar Hard X-ray (HXR) observations with RHESSI data and methods for spectral inversion allow us to study model-independent mean electron flux spectra in solar f…
Problems and Progress in Flare Fast Particle Diagnostics
John C. Brown, Eduard P. Kontar
Recent progress in the diagnosis of flare fast particles is critically discussed with the main emphasis on high resolution Hard X-Ray (HXR) data from RHESSI and coordinated data fr…
Regularized energy-dependent solar flare hard x-ray spectral index
Eduard P. Kontar, Alexander L. MacKinnon
The deduction from solar flare X-ray photon spectroscopic data of the energy dependent model-independent spectral index is considered as an inverse problem. Using the well develope…
Fast electron slowing-down and diffusion in a high temperature coronal X-ray source
Ross K. Galloway, Alexander L. MacKinnon, Eduard P. Kontar +1
Finite thermal velocity modifications to electron slowing-down rates may be important for the deduction of solar flare total electron energy. Here we treat both slowing-down and ve…
