Query: Halpha with Heating by Particle Beams   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-consistently. We focus on the influence of the
non-thermal collisional rates and the return current. Based on our results, we
propose a diagnostic method for determination of the particle beam presence in
the formation regions of the Halpha line.
