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.”

The Central Bank of the UAE (CBUAE) has imposed a financial penalty of Dh3 million on a local bank for failing to comply with anti-money laundering (AML) regulations.

The fine was issued under Article 14 of Federal Decree Law No. (20) of 2018 on Anti-Money Laundering and Combatting the Financing of Terrorism and Illegal Organisations, as well as Article 137 of the Decretal Federal Law No. (14) of 2018 concerning the Central Bank and regulation of financial institutions.

The CBUAE said the penalty followed an investigation which found that the bank had not met regulatory requirements outlined in UAE legislation to combat financial crime.

In a statement, the Central Bank reaffirmed its commitment to maintaining the transparency and integrity of the country’s financial system. “We continue to supervise and regulate all licensed financial institutions to ensure full compliance with UAE laws, regulations, and standards,” the authority said.

The name of the bank was not disclosed.

Dubai’s Roads and Transport Authority (RTA) has urged transport operators to strictly follow regulations covering all modes of passenger transport, including chartered buses, tourist services, and international bus trips.

This comes after RTA completed over 15,500 inspections targeting operators in these sectors, as part of ongoing efforts to raise service standards and ensure safety.

“The inspections weren’t just about issuing violations,” said Saeed Al Balooshi, Director of Passenger Transport Activities Monitoring at RTA. “They’re designed to improve service quality and ensure operators meet the rules that keep Dubai’s transport sector running smoothly.”

Checks included verifying safety measures onboard and ensuring all required licences were in place. The RTA also teamed up with other authorities, including Dubai Police and the General Directorate of Residency and Foreigners Affairs at Hatta Border Post, to tackle misuse and irregularities in cross-border transport services.

Al Balooshi added that the authority is using new technologies to make inspections more effective by analysing violations and measuring the impact of enforcement campaigns. “Our goal is to ensure a reliable and high-quality experience for residents, visitors, and tourists, and to protect the reputation of Dubai’s public transport sector,” he said.

Residents and motorists in Abu Dhabi should take note: new Mawaqif paid parking zones have been activated in several areas across the city, Q Mobility announced on Thursday, July 10.

The newly introduced paid zones include:

  • Eastern Mangroves
  • Dolphin Park
  • Al Khaleej Al Arabi Street sectors – specifically at Al Khaleej Al Arabi Park 1, 2, 4, and 5
  • Al Qurm Plaza

The rollout of the Mawaqif system in these areas is now officially in effect, aligning with Abu Dhabi’s parking regulations.

  • Standard Parking – black and blue curbs:
    • Dh2 an hour
    • Dh15 for 24-hour parking
  • Premium Parking Abu Dhabi – white and blue curbs: AED 3 an hour

According to Q Mobility, this move is part of ongoing efforts to better regulate vehicle movement, ease congestion, and improve the overall efficiency of public parking across the emirate. The changes follow the completion of infrastructure upgrades such as curb painting, installation of directional and awareness signage, and public notifications.

The company has also encouraged drivers to make use of the Darb app for digital payment and to carefully follow posted instructions to avoid fines.

The expansion of Mawaqif is part of a broader strategy aimed at improving traffic flow and providing smarter, more streamlined parking solutions within Abu Dhabi Island and beyond.
