NYU Abu Dhabi researchers find mysterious new set of waves in Sun

Published

on

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.”

New York Strikers crowned new champions of Abu Dhabi T10

Published

New York Strikers wiped away the pain of last edition’s loss to Deccan Gladiators in the final and crowned themselves as the new champions of the Abu Dhabi T10 in the seventh edition at the Zayed Cricket Stadium by recording a seven-wicket win. 

Pakistan’s Asif Ali, known for his power-hitting skills, and skipper Kieron Pollard, put on an unbeaten 56 runs partnership for the fourth wicket in 29 balls. Ali remained unbeaten on 48 off 25 balls with four sixes and two boundaries while Pollard scored an unconquered 21 off 13 balls with one boundary and a six to win the final with four balls to spare. They thus lifted the trophy and received the prize money of $100,000. 

It was a creditable show from New York Strikers that had become part of the Abu Dhabi T10 only in the last edition and have reached the final in both the editions and now won the title too.

Gladiators, who were hoping to record a hat-trick of title triumphs having won the earlier two editions, received  the runners-up prize money of $50,000. Their plans to post a big total was squashed by Sunil Narine who bagged two wickets for six runs from his two overs and restricted Deccan Gladiators to 91 for 5. It was the same total that New York Strikers were restricted to in the last edition’s final that Gladiators won by 37 runs.

Tale of the final battle for supremacy

The tale of the final unfolded with New York skipper Pollard winning the toss and electing to bowl.  Gladiators’ heavy scorer and aggressive batter Tom Kohler-Cadmore, who has often hit the first ball of the innings to a boundary, did that to Mohammad Amir steering him past point. He also hit the second delivery through deep cover for another boundary.  Twelve runs came off the first over.

Muhammad Jawadullah, who bowled the second over too found his first ball race to the boundary. The author of that shot was skipper Nicholas Pooran who elegantly picked the gap between gully and short third man. Pooran also hit Jawadullah’s fifth delivery over gully to pick another boundary. The last ball of the over too went for a boundary over backward point. Twenty-four runs were scored in the first two overs.

Sunil Narine, hailed as a mystery spinner, struck to end the innings of Kohler-Cadmore on unlucky 13 with a ball that turned and hit the middle stump. Worse was to follow. In the third over England’s right arm pacer George Scrimshaw got Pooran out caught by Narine at extra cover for 15.

Andre Russell joined Andre Fletcher, a pair that is capable of tearing apart any attack. However, their partnership lasted only eight runs. Narine sturck again with the fourth ball of his second over forcing Fletcher to pull into the hands of Odean Smith for 5. By the half way mark, Deccan Gladiators were struggling at 37 for 3.

Imad Wasim and Russell tried hard to pull their team to a strong total. But Jawadullah strangled the runs with his accurate five deliveries and removed Wasim with the last ball of that over for 3. Asif Ali at extra cover pulled off a stunning catch diving to his right and produced a one-handed catch.

Scrimshaw was re-introduced for the seventh over and Russell hit the second six of the innings over mid-wicket off his second delivery. He also pulled him for another six over deep square leg.  With only three more overs to go, Gladiators’ score read an unimpressive 57 for 4.

Akeal Hosein, who produced a hat-trick in Qualifier 1 against Samp Army, struck with the first ball of the eighth over to get Fabian Allen caught at deep mid-wicket by Asif Ali for 1. He also gave away just six runs only in that over. Half the side was back in the dug-out for 63.

Russell fought a lonely battle and finally top edged Amir’s first ball of the ninth over the wicketkeeper for a boundary. David Wiese pulled Amir’s fifth ball for a six and the last ball for a boundary.

Wiese hit Hosein, who bowled the last over, was hit for a six off the second delivery. But  that is the only big hit that came of that over. The pair had put on an unbeaten 34 runs in 17 balls for the sixth wicket. Russell remained unbeaten on 30 off 18 balls with two boundaries and two sixes and Wiese unconquered on 20 off 11 balls with two sixes and a boundary for a total of nine runs short of the 100 run mark.

Asif and Pollard’s stubborn batting show

The chase began with Trent Bout bowling at full pace to New York openers  Rahmanullah Gurbaz and Muhammad Waseem. With the fifth ball, he trapped Waseem on 6, leg before with a ball that nipped back. Nuwan Tushara too produced a beauty to clean bowl Rahmanullah Gurbaz for 1. The ball went through his defense to hit the wicket.

Asif Ali joined Niroshan Dickwella and flicked the first ball he faced for a boundary to fine leg. The crowd whistled for the batters but Boult who bowled the third over gave away only one boundary to Dickwella. In the fourth over, Asif Ali gave the crowd what they wanted. He hit Imad Wasim for two sixes off the third and fifth ball both to deep mid-wicket.

Russell struck in the fifth over by removing Dickwella caught by Khawaja Nafay at mid-on for 14. At the half-way mark, New York needed 50 runs off the remaining five overs. Asif Ali hit Waqar Salamkheil’s first delivery for a boundary. Pollard smashed Waqar for a six over mid-wicket to make it anybody’s game.

Asif also hit Thushara for a six off the first ball of the seventh over to long off. Pollard and Asif also ran for quick runs and took 14 runs off Thushara’s over to turn the target into a gettable 25 for 18 balls.

UAE’s Zahoor Khan was introduced for the eighth over and Asif hit Zahoor’s fifth delivery for a six and made it 14 runs from 12 deliveries. Pollard cracked a boundary off Russell’s third delivery of the ninth over to make it five runs off the last over. The pair put on a 50 runs partnership off the first ball of the last over from Zahoor to take the trophy away from Gladiators.

Tom-Kohler Cadmore’s 27-ball fifty sealsmassivewin for Deccan Gladiators over New York Striker

Published

Deccan Gladiators continued their winning run over New York Strikers in the glitzy opening encounter of the 7th edition of Abu Dhabi T10. The night saw enthralling dance performances along with a glamourous fashion show, along with a memorable performance from Tom Kohler-Cadmore, who smashed an unbeaten 68 off 33 balls to help the defending Champions to their first win to kick off the season.

An exciting buzz engulfed the Sheikh Zayed Stadium as the Gladiators stepped out to bat on a pristine surface, covered with a nice patch of grass. The cool winds in the city only made the conditions perfect for cricket. Shaji Ul Mulk, Chairman, T10 Sports Management, declared the tournament open with a motivating speech and the action began in Abu Dhabi. Pollard-led New York Strikers strategically opted to bowl first.

Unleashing Mohammad Amir to use the swing offered by the surface, the Strikers shackled the openers Nicholas Pooran and Kohler-Cadmore. Pooran’s early dismissal by pacer Muhammad Jawadullah made things trickier for the Champions. With runs hard to come by, pressure built on Gladiators that led to Andre Fletcher getting run out after a horrible mix-up.

The dynamic Andre Russell began counter-attacking with innovative shots. But a failed big hit from the power-hitter on Ali Khan’s off-cutter landed straight in Pollard’s hands. Not letting the momentum slip away, Kohler-Cadmore struck Sunil Narine for two sixes in the next over. Chamika Karunaratne handed a double whammy to Gladiators on consecutive deliveries, but Kohler-Cadmore waged a lone battle, and hamered a 27-ball fifty. The England batter’s brave innings led Gladiators to 118/8 in 10 overs.

As Strikers began their chase, left-arm speedster Trent Boult handed Deccan Gladiators their first blow, dismissing the dangerous Rahmanullah Gurbaz. Kusal Perera tried to counter-attack after the dismissal, but fast bowler Zahoor Khan picked his wicket to put his side in control. As the Gladiators missed three simple catches in the first couple of overs, the momentum slipped away.

The defending Champions brought in substitute Nuwan Thushara to replace Kohler-Cadmore under Impact Player rule. As per the rule, Thushara was allowed to bowl, but the right-arm speedster was struck for boundaries by Muhammad Waseem. His fiery innings came to an end in the next over by Luke Wood with Imad Wasim finally catching one. As Asif Ali held one end, skipper Kieron Pollard stepped out to provide some momentum in the steep run-chase. With 36 needed off the final 2 overs, Ali and Pollard were dismissed in quick succession. Gladiators sealed the win by 22 runs.
