NYU Abu Dhabi researchers find mysterious new set of waves in Sun
Researchers from NYU Abu Dhabi’s (NYUAD) Centre for Space Science have discovered a new set of waves in the Sun that, unexpectedly, appear to travel much faster than predicted by theory.
In the study, ‘Discovery of high-frequency-retrograde vorticity waves in the Sun’, published in the journal Nature Astronomy, the researchers, led by Research Associate Chris S. Hanson, detailed how they analysed 25 years of space and ground-based data to detect these waves. The high-frequency retrograde (HFR) waves, which move in the opposite direction of the Sun’s rotation, appear as a pattern of vortices (swirling motions) on the surface of the Sun and move at three times the speed established by current theory.
The interior of the Sun and stars cannot be imaged by conventional astronomy (e.g. optical, x-ray etc.), and scientists rely on interpreting the surface signatures of a variety of waves to image the interiors. These new HFR waves may yet be an important puzzle piece in our understanding of stars.
Complex interactions between other well known waves and magnetism, gravity or convection could drive the HFR waves at this speed. “If the HFR waves could be attributed to any of these three processes, then the finding would have answered some open questions we still have about the Sun,” said Hanson. “However, these new waves don’t appear to be a result of these processes, and that’s exciting because it leads to a whole new set of questions.”
This research was conducted within NYUAD’s Centre for Space Science in collaboration with the Tata Institute of Fundamental Research (TIFR) and New York University, using NYUAD and TIFR’s computational resources. By studying the Sun’s interior dynamics – through the use of waves – scientists can better appreciate the Sun’s potential impact on the Earth and other planets in our solar system.
“The very existence of HFR modes and their origin is a true mystery and may allude to exciting physics at play,” said Shravan Hanasoge, a co-author of the paper. “It has the potential to shed insight on the otherwise unobservable interior of the Sun.”
Drivers heading towards Sharjah University City have been given some relief with the partial reopening of a busy route, but motorists using the Industrial Area 17, Maliha Road corridor should prepare for a new traffic diversion from Wednesday, August 26.
Sharjah’s Roads and Transport Authority has reopened two lanes in each direction along a stretch connecting Industrial Area 17, University Bridge and University City.
The reopening restores part of a key route between University City and the Institutes Land area, which had been affected by ongoing roadworks.
New diversion starts August 26
The reopening comes as another section of the road network is partially closed as part of the Etihad Rail Station Access Roads Project.
From Wednesday, motorists travelling from Industrial Area 17 towards Maliha Road will be diverted onto an alternative route.
Drivers heading to Sharjah English School, Nesto Hypermarket and nearby businesses should therefore allow extra time and follow the signed diversion rather than attempting to use their usual approach.
How long will the diversion last?
The temporary diversion is expected to remain in place for just over five weeks, from August 26 until October 5.
The works are part of the wider infrastructure programme supporting the development of the Etihad Rail network in Sharjah.
While the project is expected to improve connectivity in the long term, drivers can expect changes to traffic movements while the access roads are being constructed.
What drivers should know
- University City route: Two lanes in each direction are now open along the reopened section.
- New closure: The Industrial Area 17-to-Maliha Road route will be partially closed from August 26.
- Affected destinations: Drivers heading towards Sharjah English School, Nesto Hypermarket and nearby businesses should use the designated alternative routes.
- End date: The diversion is scheduled to remain until October 5, 2026.
- Drive carefully: Follow directional signs and safety instructions around the work zones.
- Allow extra time: Traffic conditions may change during peak periods as motorists adjust to the diversion.
The Roads and Transport Authority has published a map showing the approved alternative routes. Drivers are advised to check the diversion before setting off and follow the road signs once they reach the affected area.
