Discovery of Confined Pseudo-shocks as a New Energy Source for the Heating of Sun’s Corona

The Sun’s outer corona consists of plasma whose temperature exceeds one million degrees. This extremely hot corona is located only a few hundred kilometres above the solar surface known as the photosphere that maintains its temperature around 6000 degrees. A longstanding problem is the energy source for the corona and a mechanism that deposits this energy and heats the corona to such high temperatures. Despite numerous space and ground-based observations, and extensive theoretical efforts, the problem still remains unsolved. This is not surprising as the problem is very complex and its full solution requires a unique combination of new solar observations and novel theories dealing with the formation of the solar atmosphere and its magnetic fields. Such unique approach undertaken by a group of researches has been completed and the obtained results are briefly described in the following.
