Researchers at Northumbria University have come up with a new finding pertaining to the Sun’s magnetic waves. The findings published in the latest issue of Nature Astronomy – a prominent science journal.
The finding is on the basis of a 10-year study by researchers at the University’s Department of Mathematics, Electrical Engineering, and Physics. The finding says magnetic waves in the corona of the Sun respond to sound waves that escape the Sun’s core.
Sun’s Magnetic Waves Respond to Leaked Innermost Sound Waves, says Research
Termed Alfvénic waves, the Sun’s magnetic waves have a crucial role to do. This involves transport of energy around the star and the solar system. According to the earlier theory, the Sun’s magnetic waves originated at the surface, with boiling hydrogen temperatures reaching 6,000 degrees. In addition, the Sun’s surface churns the magnetic field for energy transfer.
However, the new finding has something else to say. This says magnetic waves react high in the atmosphere triggered by sound waves escaping the Sun’s core. So much so, the sound waves leave a distinct mark on the magnetic waves. In response to the sound waves, the marker amounts to shaking of the Sun’s entire corona in a collective manner. The vibration is experienced over a broad frequency range.
To strengthen the finding, researchers examined the behavior of the new marker over the entire10-year study period. The finding thus suggests the newly discovered marker is a fundamental constant of the Sun. The new marker also holds potential to be a basic constant of other stars, adds the report.
As a result, the findings serve to have significant implications for current ideologies pertaining to magnetic energy.
