Scientists are working on a method for accurately predicting magnetic storms

The new work will help predict magnetic storms that depend on the Sun’s heating anomaly.

Scientists around the world have been working for 70 years to find out the reasons for the abnormal heating of the solar corona. This process is associated with magnetic storms, which are still impossible to accurately predict.

The temperature of the solar corona – the outer layer of the Sun’s atmosphere – is about 1 million degrees Celsius, and in some places it reaches almost 10 million. However, the lower atmosphere reaches only 5.5 thousand degrees.

As a result, the conclusion: the farther from the center of the Sun, the hotter, although inside it the opposite is true. The mechanism of operation of this heating of the corona is still unclear.

Our research team is studying the effect of radiation cooling and various plasma heating processes on wave dynamics in the upper layers of the solar atmosphere. A more complete knowledge of the wave dynamics in the solar atmosphere will improve the existing mathematical models describing the Sun.

The press service of the Samara National Research University named after academician S.P. Korolyov.
Alfvén waves are one of the most probable carriers of energy in the solar atmosphere. They are like vibrations of a stretched string. In their work, scientists have confirmed the influence of radiation cooling and various plasma heating processes on Alfvén waves of large amplitude.

Samara scientists investigate the propagation of Alfvén waves 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 the solar coronal plasma.

Scientific results can also help in the development of thermonuclear energy, which could give humanity colossal amounts of energy.
