Prof Makgalwa
Prof Matseliso Mokhele-Makgalwa: Vice Dean; Research, Engagement and Internationalisation in the Faculty of Education at the University of the Free State (UFS).

The Faculty of Education at the University of the Free State (UFS) proudly announces the appointment of Prof Matseliso Mokhele-Makgalwa as Vice Dean of Research, Engagement and Internationalisation, effective 1 January 2024. With a wealth of experience and a fervent dedication to academic advancement, Prof Mokhele-Makgalwa’s appointment marks a significant stride towards enhancing the faculty’s global presence and academic prowess. 

Transitioning into a new role

Transitioning seamlessly from her previous role as Acting Vice Dean of Research and Postgraduate Studies, Prof Mokhele-Makgalwa perceives this new appointment as a natural progression, elevating her responsibilities to spearhead research endeavours, foster engagement, and cultivate international partnerships within the faculty. Embracing this pivotal role with enthusiasm, she underscores the importance of collaborative efforts among faculty members, securing research funding, and ensuring the quality and impact of scholarly outputs. 

“I appreciate the opportunity to contribute significantly to the faculty’s research, engagement and internalisation efforts,” says Prof Mokhele-Makgalwa. “I look forward to collaborating with the faculty staff members to advance our academic initiatives on a broader scale.”  

A vision of progression for the faculty

At the heart of her vision lies a commitment to realise the UFS’s Vision130, wherein Prof Mokhele-Makgalwa aims to elevate the international profile of the faculty, foster impactful research, promote engaged scholarship, and facilitate knowledge exchange on a global scale. Her strategic objectives also include positioning the faculty among the top three education schools nationally, reflecting her dedication to academic excellence and institutional advancement.

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.
