Formation of Balmer Lines in Impulsively Heated Flare Atmosphere by Neutral Beams
Original language description
In the context of interpreting non-thermal hard X-ray emission and ? lines emanating from the footpoints of flare loops, most contemporary flare models assign a fundamental role during the flare energy release, transport and deposition to the high energynon-thermal particle beams. In this contribution we concentrate on modelling of the spectroscopic properties of chromospheric flare emission in optical hydrogen lines generated due to the bombardment of the chromosphere and photosphere by neutral beamswith power-law spectra. In order to obtain an estimate of the neutral beam flare heating in the solar atmosphere we produced a simple model describing the propagation and thermalisation of neutral beams. We compare the neutral beam flare heating with theflare heating produced by corresponding pure electron and proton beams. Further we compare the contribution functions for H? line obtained for neutral and electron beam heating.
