Scientists around the world have been working for 70 years to find out the causes of the anomalous heating of the solar corona.
Temperature of the solar corona - the outer layeratmosphere of the Sun - is about 1 million degrees Celsius, and in some places reaches almost 10 million. However, the lower layers of the atmosphere reach only 5.5 thousand degrees.
As a result, the conclusion is: the further from the center of the Sun, the hotter it is, although inside it the opposite is true. The mechanism by which this corona heating works is still unclear.
Our research team is studying the impactradiative cooling and various plasma heating processes on the dynamics of waves in the upper layers of the solar atmosphere. More complete knowledge of wave dynamics in the solar atmosphere will improve existing mathematical models describing the Sun.

One of the most likely energy carriersAlfvén waves are present in the solar atmosphere. They are similar to vibrations of a stretched string. In their work, scientists confirmed the influence of radiation cooling and various plasma heating processes on large-amplitude Alfvén waves.
Propagation of Alfven waves Samarascientists study using the equations of magnetic gas dynamics. Based on the results of the work, scientists will present systems of equations that mathematically accurately describe various parameters and models of heating of the solar coronal plasma.
Scientific results can also help in the development of thermonuclear energy, which could provide humanity with colossal amounts of energy.
