Estudio del balance de energía en la corona solar con tres y cuatro bandas de SDO/AIA
Abstract
A semi-empirical technique was developed to estimate the energy flux input required at the coronal base of magnetic loops in the quiet corona so that they are thermodynamically stable. This technique combines three-dimensional reconstructions of electronic density and temperature, based on differential emission measure tomography (DEMT), with potential extrapolations of the magnetic field measured in the photosphere. This technique was applied using three EUV bands with thermal sensitivities in the range of characteristic coronal temperatures, from to 2 MK. We expand the observed temperature range using a fourth band, whose range of sensitivity reaches MK.
