Abstract

The detailed thermal structure of the magnetized solar transition region, as measured by itsdeferential emission measure [DEM(T)], is poorly known. Building on the fact that the solar surface is strongly magnetized and thereby structured, proposals have been made that envision a significant lower-temperature contribution to the energy balance from (ion) heat fluxacross an arcade of different temperature loops. In this paper, we describe aself-consistent, 2-D, MHD simulation, which includes the full thermal effects of parallel stability and anisotropic conduction, of a nested-loop model of the thermal and magnetic structure of the transition region. We then demonstrate that the predicted DEM agrees with observations in the conceptually elusiveT < 105K regime.
