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.”

UAE weather alert: Rain expected in parts of country as temperatures set to soar

Published

Spread the love

While much of the UAE continues to swelter under intense summer heat, residents in the eastern regions have something to look forward to: some rain.

According to the National Centre of Meteorology (NCM), conditions today will be generally fair to partly cloudy, with convective clouds expected to develop over eastern parts of the country, bringing the possibility of rainfall. Some inland areas could also experience rain later in the afternoon.

Temperatures near 46°C

Despite the rain forecast, temperatures are expected to stay exceptionally high across most of the UAE.

Dubai is forecast to reach a scorching 45°C, while Abu Dhabi and Sharjah are expected to reach 44°C. The hottest locations today will be Al Ain and Liwa, where temperatures could climb to 46°C.

Fujairah is likely to be the coolest emirate thanks to the expected cloud cover and rainfall, with temperatures peaking at around 38°C.

Across the country, coastal areas are expected to see temperatures between 37°C and 43°C, while inland regions could reach between 44°C and 48°C.

Dusty conditions in some places

The NCM has also warned of dusty conditions as winds strengthen throughout the day.

Light to moderate southeasterly winds are expected to shift northwesterly, reaching speeds of up to 40km/h in some areas. These stronger winds could lift dust and sand, particularly in exposed and open areas, reducing visibility for motorists.

Drivers are advised to remain cautious on the roads and stay alert to changing visibility conditions.

Calm seas

For those planning a seaside outing, conditions are expected to remain relatively stable.

The Arabian Gulf is forecast to experience slight seas, with wave heights between two and three feet. Meanwhile, the Sea of Oman is expected to be slightly rougher, with slight to moderate conditions and waves reaching up to four feet.

With temperatures remaining firmly in the mid-40s, any rainfall over the eastern regions will provide a welcome break from the summer heat, even if only temporarily.

Dubai rolls out ‘Flexi Rents’ to support tenants with payment relief

Published

Dubai has launched a new initiative aimed at making housing more affordable by allowing tenants greater flexibility in how they pay their rent.

The programme, known as Flexi Rents, was announced by the Dubai Land Department (DLD) on Tuesday and will initially be rolled out through 12 participating real estate companies.

Under the scheme, tenants will be offered a range of payment options, including monthly rent instalments, extended payment plans of up to 12 months, grace periods and revised payment schedules. In some cases, landlords may also waive rental increases.

Khalid Al Shaibani, Director of the Rental Affairs Section at the DLD, said the initiative was intended to improve housing stability and help residents manage rising living costs.

“The Affordable Rental Initiative reflects Dubai’s commitment to promoting housing stability and supporting residents through flexible and accessible rental solutions,” he said.

The programme will be available to both new and existing tenants. Residents currently paying rent through annual or multiple-cheque contracts can request revised payment arrangements from participating landlords and property management companies.

The DLD said some administrative fees associated with delayed cheque payments could also be waived. Tenants will be able to pay using a variety of methods, including credit cards, debit cards and cheques.

Officials said the initiative is expected to expand beyond the initial group of participating companies in the coming phases.

“This is only the beginning,” Mr Al Shaibani said, adding that further measures aimed at enhancing quality of life in Dubai would be announced in the months ahead.

According to DLD figures, nearly 1.2 million tenancy contracts, including new leases and renewals, were recorded in Dubai last year, underlining the scale of the emirate’s rental market.
