On Detection of Balmer-Series Lines Response to Accelerated Particles in Solar Flares

Popis výsledku v původním jazyce

We studied the H? and H? lines and the ratio of the line profiles for several solar flares observed with a high cadence to find and to analyze variations predicted from the theoretical simulations of Kašparová & Heinzel (2002). The profiles extracted atindividual kernels during different flare phases were analyzed with respect to the radio and X-ray data patterns. We found that the theoretical predictions of the H?/H? line profile ratios and the observations were in a good qualitative agreement. However, as concerns quantitative correspondence, we found some difference in position of the predicted profile ratio maxima, moment of arising and the duration of the effect, influence of energy cutoff of electron beam. We try to find some explanations for those discrepancies and discuss perspectives of simultaneous observations of Balmer series lines.
