Abstract:
Most coronal heating studies focus in active regions, but heating phenomena also take place in the quiet diffuse corona. Using differential emission measure tomography (DEMT) of EUV image time series, in combination with potential extrapolations of the global coronal magnetic field, it is possible to estimate the energy flux in the lower corona required to maintain thermodynamically stable structures. We present results of this type of analysis based on both EUVI/STEREO and AIA/SDO EUV data, and MDI/SOHO synoptic magnetograms. We discuss the implications of our results to coronal heating models.
