Sun found to emit waves that travel 3 times faster than previously

Researchers have detected a mysterious group of waves emanating from the Sun that inexplicably, seem to travel three times faster than previously predicted. The researchers think these waves may help them understand the interior of the Sun, which is not normally observed even by space-based telescopes. Described as a “true mystery,” these waves were discovered when researchers studied 25 years of data collected on the Sun from both space and Earth. These high-frequency retrograde (HFR) waves appear as swirls or vortices on the solar surface and travel in the opposite direction of the Sun’s rotation.

The most surprising aspect of the research, a collaboration between New York University and the Mumbai-based Tata Institute of Fundamental Research (TIFR), was that these waves traveled at three times the speed established by current theory. This leads researchers to believe that there may be additional physiological processes at work that are not yet understood.

Studying these waves is also important to know what is happening within the inner regions of the Sun. The interior of the Sun and stars cannot be imaged by conventional instruments such as optical or X-ray telescopes. Therefore, scientists rely on the interpretation of surface waves. These new HFR waves may be an important puzzle in our understanding of stars.

However, researchers are currently focused on understanding what causes these waves to move so fast. Some possible explanations include interactions between other well-known waves and magnetism, gravity, or convection.

“The as yet undetermined nature of these waves promises novel physics and new insights into solar dynamics,” the researchers say. wrote In their study published in the journal Nature Astronomy.

“The existence of HFR modes and their origins is a true mystery and may provide clues to the exciting physics in the game,” said Shravan Hansoghe, co-author of the paper, said in a statement that it has the potential to provide insight into the Sun’s otherwise “invisible interior.”

Scientists hope that by studying the waves, they will be able to understand the effect of the Sun on Earth and other planets in the Solar System.
