Resumen:
During solar activity minima, the coronal magnetic structure consists of closed magnetic loops located mostly around the solar equator and loops open to the interplanetary medium near the poles. In order tohave thermodynamically stable loops, at typical million degree coronal temperatures, some heating mechanism is necessary to compensate for the energetic loses observed along the loops. In a previous work, we developed a procedure to estimate, using Dierential Emission Measure Tomography in combination with global coronal magnetic field extrapolations, the energy input flux at the loops coronal base. In this work, we use the energy flux computation to model quiet-sun coronal loops with the 0D hydrodynamic model, Enthalpy-Based ThermalEvolution of Loops (EBTEL). The aim is to compare the obtained results with the thermal properties of coronal loops reconstructed with the DEMT-PFSS technique.
