The rotation in the northern hemisphere is always antisymmetric to the rotation in the southern hemisphere. These mysterious waves travel in the opposite direction of the Sun's rotation, spinning to the right three times faster than hydrodynamics alone would allow. NYU Abu Dhabi
Researchers at NYU Abu Dhabi's Center for Space Science (NYUAD) have discovered a new set of waves in the sun that unexpectedly appear to be moving much faster than theory predicted.
In a study in the journal Nature Astronomy, "Discovery of high-frequency retrograde vortex waves in the sun," researchers led by research associate Chris S. Hanson detail how they analyzed 25 years of space and ground data to discover them these waves. High-frequency retrograde (HFR) waves in the opposite direction of the Sun's rotation appear as vortices (vortex motion) on the Sun's surface and travel three times faster than current theories determine.
Traditional astronomy (e.g. optics, X-rays, etc.) cannot image the interior of the sun and stars, and scientists rely on interpreting the surface features of various waves to image the interior. These new HFR waves may be another important piece of the puzzle in our understanding of stars.
Complex interactions between other known waves and magnetism, gravity or convection can propel HFR waves at such velocities. "If HFR waves can be attributed to one of these three processes, then this discovery will answer some of the unanswered questions we still have about the existence of the Sun," Hansen said. "However, these new waves do not appear to be of these processes. As a result, it's exciting because it raises a whole new set of questions."
The research was conducted at the NYU Space Science Center in collaboration with the Tata Institute for Fundamental Research (TIFR) and NYU using NYU and TIFR computing resources. By using waves to study the Sun's internal dynamics, scientists can better assess the Sun's potential impact on Earth and other planets in our solar system.
"The existence of the HFR mode alone and its origin is a real mystery that may hint at some exciting physics," said Shravan Hanasoge, co-author of the publication. "It has the potential to give insights into otherwise unobservable insights. internal
