Simulated hydrodynamic responses to beam electron injection. The simulated hydrodynamic responses of a flaring atmosphere to the injection of a beam with the initial flux of 4.3 × 10¹¹ erg cm⁻² s⁻¹ and spectral index of 3.9 obtained from the conversion of a spectral index of HXR emission to that of electron beam Zharkova & Gordovskyy (2006) showing the column depth dependencies of electron kinetic temperature, K (panel a), the plasma density, cm⁻³ (panel b), plasma macrovelocity, km s⁻¹ (panel c) and linear heights (panel d).
