The solar corona is the outer layer of the star's atmosphere
A new study from the University of Northumbria was able to show that the behavior of magnetic solar waves is different from scientific expectations. Information for a 10-year observation period suggests that the magnetic waves in the solar corona (outer atmospheric layer) react to sound waves coming from inside the star.
These magnetic waves (Alfven) play a crucial role in the transport of energy around the sun and the entire solar system. Earlier it was believed that the waves are formed on a stellar surface, where the temperature mark of boiling hydrogen reaches 6000 degrees and “beats” the magnetic field.
However, new information suggests that magnetic waves are activated higher in the atmosphere by sound waves. The latter leave a remarkable marker on magnetic waves. The presence of traces suggests that the entire star corona shakes together in response to the sound waves. Vibrations are created in the pure frequency range. The newly found marker is visible throughout the entire crown, and its presence is recorded over a 10-year study period. That is, we have a fundamental solar constant, which is capable of spreading to other stars. Now you can better understand how magnetic energy is transmitted and used in stellar atmospheric layers.
The solar corona is 100 times hotter than the surface. It is believed that the energy created by Alfven waves is responsible for heating the corona to a temperature of a million degrees. In addition, these waves are responsible for the rise in temperature and the acceleration of powerful solar winds to a figure of a million miles per hour.
Now a team of scientists working with NASA to analyze photos of the Sun, obtained using a high-resolution coronal scanner Hi-C.
