Insights into coronal heating and mechanisms of energy transport in the solar atmosphere from IRIS observations
  Astronomy and astrophysics

Wednesday 13 May 2015
from 10:30 to 11:30

Speaker : Paola Testa (Harvard-Smithsonian Center for Astrophysics)
Abstract : Joint observations of solar active regions with Hinode (XRT and EIS), SDO/AIA and IRIS, cover from the upper photosphere to the corona at high spatial, temporal and spectral resolution. I will discuss how these observations, coupled with detailed HD and MHD modeling including chromosphere, transition region and corona, provide tight constraints on the mechanisms of energy transport and heating of the plasma to coronal temperatures. I will present recent results of analysis of observed variability of emission at the footpoints of coronal loops, and I will show how the modeling of rapid moss brightenings provides diagnostics for the presence and properties of non-thermal particles in nanoflares, which are below the detectability threshold of existing hard X-ray observations.
