Chromospheric heating in a flare region by heat and particle fluxes
Abstract
An efficient method for calculating the thermal structure of a flare region is developed by using an analytical asymptotic solution at the low-temperature end of the region. This method is employed to solve a problem concerning flare-region heating by a thermal flux and an accelerated electron flux with allowance for radiative cooling. The case of hydrostatic equilibrium in the presence of gravity is considered, and the boundary conditions are analytical solutions to the asymptotic equations valid in the low-temperature flare region. It is found that a solution that takes into account the particle contribution to heating differs only slightly from that for the case of localized heat sources.
