[2.09] Hot versus cool coronal loops

S. Patsourakos, J. A. Klimchuk, S. K. Antiochos (Naval Research Laboratory)

EUV and SXR observations show respectively that cool (1 MK) loops are finer and maybe more dynamic than hotter (2 MK) ones. Whether this reflects a fundamental difference in the properties of the heating mechanism in action in each loop class is not yet clear. We will address some aspects of this issue by combining EUV and SXR observations of such loops with eventually hydrodynamic simulations of a nano-flare heated corona.

Research supported in part by ONR and NASA.
