Resumen:
The 1 MK characteristic temperature of the solar corona is ∼ 200 hotter than that of the photosphere. The causes for such heating have a magnetic origin and several possible mechanisms have been proposed. Most studies on coronal heating focus on active regions, but the so called quiet sun, or diffuse corona, is also subject to heating phenomena. By combining differential emission measure tomography (DEMT) applied to EUV images time-series, with potential extrapolations of the coronal magnetic field, it is possible to estimate the radiative energy loss along coronal loops of the diffuse corona, and the energy flux that is required at their footpoints to maintain thermodynamically stable structures. In this work we show preliminary results of our calculations using the DEMT.
