Fast Spectral Fitting of Hard X-Ray Bremsstrahlung from Truncated Power-Law Electron Spectra
J. C. Brown, J. Kasparova, A. M. Massone +1
Hard X-Ray bremsstrahlung continuum spectra, such as from solar flares, are commonly described in terms of power-law fits, either to the photon spectra themselves or to the electro…
Hydrogen Balmer line formation in solar flares affected by return currents
Jiri Stepan, Jana Kasparova, Marian Karlicky +1
Aims. We investigate the effect of the electric return currents in solar flares on the profiles of hydrogen Balmer lines. We consider the monoenergetic approximation for the primar…
Halpha with Heating by Particle Beams
J. Kasparova, M. Varady, M. Karlicky +2
Using 1D NLTE radiative hydrodynamics we model the influence of the particle beams on the Halpha line profile treating the beam propagation and the atmosphere evolution self-consis…
Hard X-ray Spectra and Positions of Solar Flares observed by RHESSI: photospheric albedo, directivity and electron spectra
J. Kasparova, E. P. Kontar, J. C. Brown
We investigate the signature of the photospheric albedo contribution in solar flare hard X-ray spectra, the effect of low energy cutoffs in electron spectra, and the directivity of…
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…
