Springboks
Prof Francis Petersen, UFS Rector and Vice-Chancellor, paid a special visit to the Springboks in 2018 before they faced England in Bloemfontein. From the left are Jacques Nienaber (Springbok assistant coach), Oupa Mohoje (Springbok), Prof Petersen, Rassie Erasmus (Springbok head coach), and Swys de Bruin (Springbok consultant coach at the time). De Bruin, Erasmus, Nienaber, and Mohoje are all Kovsie alumni.


Like the rest of the country, we are behind our Springboks all the way. This is what Prof Francis Petersen, Rector and Vice-Chancellor of the University of the Free State (UFS), told alumnus Rassie Erasmus in a letter this week.

Prof Petersen wrote the letter to Erasmus, the head coach of the Springboks, to wish him everything of the best in the team’s preparation and for the game on Saturday (2 November 2019) at which they face England in the Rugby World Cup final in Japan.

"On behalf of the staff and students of the University of the Free State, I would like to wish you and the Springbok team all the best with your preparations this week and for the final. I know that Saturday’s match will be played with vigour and determination,” Prof Petersen wrote.

Prof Petersen said the UFS community was extremely proud of the Springboks’ achievements during the 2019 Rugby World Cup – especially with Erasmus at the helm of the team. The Boks defeated Japan in the quarter-final and Wales in the semi-final to reach their first final since 2007.

“As a former Shimla player and Kovsie Alumnus of the Year 1998, we are truly proud of what you have achieved during your career in South African rugby, and especially during the World Cup tournament. We are also proud of our other alumni – Jacques Nienaber as defence coach, and referee Jaco Peyper.”

Peyper refereed one of the quarter-finals and will be an assistant referee in the bronze medal play-off between New Zealand and Wales on 1 November 2019.

Under Erasmus the Springboks won the Rugby Championship this year, the first time since 2010. Erasmus and Nienaber have a long relationship. They met in the army in 1991. Later Nienaber served as physiotherapist with the Shimlas and Erasmus captained the team. They worked together at the Cheetahs, Cats, Stormers, Munster and now the Springboks.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
