Query: A Unified Computational Model for Solar and Stellar Flares   We present a unified computational framework which can be used to describe
impulsive flares on the Sun and on dMe stars. The models assume that the flare
impulsive phase is caused by a beam of charged particles that is accelerated in
the corona and propagates downward depositing energy and momentum along the
way. This rapidly heats the lower stellar atmosphere causing it to explosively
expand and dramatically brighten. Our models consist of flux tubes that extend
from the sub-photosphere into the corona. We simulate how flare-accelerated
charged particles propagate down one-dimensional flux tubes and heat the
stellar atmosphere using the Fokker-Planck kinetic theory. Detailed radiative
transfer is included so that model predictions can be directly compared with
observations. The flux of flare-accelerated particles drives return currents
which additionally heat the stellar atmosphere. These effects are also included
in our models. We examine the impact of the flare-accelerated particle beams on
model solar and dMe stellar atmospheres and perform parameter studies varying
the injected particle energy spectra. We find the atmospheric response is
strongly dependent on the accelerated particle cutoff energy and spectral
index.
