Description
Coronal streamers are long lived structures of the solar corona, and are very important source of slow solar wind. We have analyzed few dozen of coronal streamers observed by AIA/SDO, from solar activity maximum to minimum. For each streamers we applied a Differential Emission Measure method to obtain both a temperature distribution and a value of average temperature as well as it’s change with height above photosphere. We find that streamers are filled with plasma with temperatures in the range of 1.2-2.0 MK. We found that average temperatures of streamers changes as a function of solar activity phase.
