Scientists have discovered another type of high wave on the surface of the sun, which moves three times faster than scientists think.
Acoustic waves, called high-frequency retrograde (HFR) vorticity waves, are seen moving backwards into the sun’s plasma on one side of its orbit. The first wave of waves was described in a study published March 24 in the journal Nature Astronomy.
Scientists can’t see the depth of the sun’s heat, so they often measure the acoustic waves moving over its skin and back to its head to see what’s going on inside. But the slow speed of the HFR waves, seen in 25 years of data from the sky and telescopes around the earth, has shown that scientists may be missing something important.

“The real existence of HFR species and their origins is a real mystery or about the interesting physics in the game,” said historian Shravan Hanasoge, an astrophysicist at Abu Dhabi’s New York University. Center for Space Science, in a word. “It can separate information because it doesn’t see the sun.”
Scientists previously thought that the nature of the acoustic waves near the surface of the sun was due to the Coriolis effect, where the dots move faster at the equator of the circle. before the dots on its posts.
When the waves appear, scientists believe that one of three processes can accelerate them in HFR waves: the solar magnetic field or its gravity that stimulates the Coriolis waves. , or super hot convection currents moving down and over his skin that could drag them away in the past. high speeds. But none of these procedures apply to the data.
“If HFR waves could be compared to any of these three processes, then the discovery would answer some of the broader questions we have about the sun,” said former author Chris Hanson, a solar physicist at New York University Abu Dhabi’s Center for Space Science. , spoken in the language.
“However, these new waves are not seen as a result of these processes, and it is gratifying because they are leading to a new question group.”
Filling in the gaps in their knowledge will help researchers better understand the interior of the sun, and better understand the effect of the sun on Earth and the other stars of the universe. Solar system. It can provide insight into the shape of a high wave, called the Rossby wave, which is seen traveling through Earth’s oceans four times faster than current models. heart.
