Resumen:
The magnetically dominated solar corona is structured in the form of loops or flux tubes. To observethis structure during minimum solar activity epochs (or in the quiescent corona) is a difficult taskbecause density and temperature inhomogeneities between loops and their surroundings are relativelylow, making them not easily distinguishable in EUV images. Differential emission measure tomography,combined with a global potential model of the coronal magnetic field (DEMT-PFSS), allows us tocharacterize physical parameters of the coronal plasma along reconstructed loops. In this work, wetomographically reconstruct Carrington Rotation (CR) 2082 that ocurred at the minimum betweenSolar Cycles 23 and 24 and we statistically analyze the thermodynamic properties of coronal loops.These results are compared with the 1D model, Hydrodynamics and Radiation Code (HYDRAD), forconstant and impulsive heating regimes.
