| Abstract: |
Comparison of the Balmer series lines with HXR and microwave
emissions are used as tools for study of the chromospheric response to effects of
accelerated particle beams in solar flares. We studied the Hα and Hβ 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 at
individual 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
Hα/Hβ 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. |
