A new type of ultra-fast wave on the sun

A new type of ultra-fast wave on the sun

Abu Dhabi: «The Gulf»
Researchers at the Space Science Center at New York University Abu Dhabi announced the discovery of a new type of solar wave, characterized by a speed that exceeds all expectations based on basic assumptions in the field of space science.
In the paper titled “The Discovery of High Frequency Reverse Spiral Waves on the Sun,” the team of researchers led by co-research scientist Chris Hanson described their efforts to analyze the amount of data that resulted from twenty-five years of observations from Earth and beyond, with the aim of identifying these high-frequency waves. The frequency that is characterized by its movement against the direction of the sun’s rotation, these waves appear in the form of vortices moving at a speed three times more than what the prevailing theories expected.
Since it is impossible to directly photograph the interior of the sun and other stars with the current astronomical techniques of optical devices and X-rays, scientists rely on indirect evidence formed by a group of radiation, and these high-frequency reverse waves may represent an important tool that contributes to our understanding of stars, and the speed of movement of the reverse waves may return High frequency leads to the complex interactions between other types of waves and the phenomenon of magnetism, gravity, or even convection.
“If we were to check if one of these factors was causing the high-frequency reverse wave velocity, we might be able to unlock some of the sun’s mysteries,” Chris Hanson said. But it does not appear to be caused by any of these factors, which in itself raises a number of new questions.”
The team carried out their research at the Space Science Center at NYU Abu Dhabi in partnership with the Tata Basic Research Center and New York University, using computational resources provided by NYU Abu Dhabi and the Tata Institute. These waves provide another way to study the dynamic interactions in the sun’s interior, helping scientists understand the potential effects of the sun on Earth and other planets in the solar system.
Shravan Hanasugi, one of the authors of the paper, said: “The high-frequency inverse waves and their source represent a real mystery that points to the existence of physical phenomena worthy of study.
