“Welcome to the South Campus of the University of the Free State!” Addressing a packed Madiba Arena, Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, said he was happy to see not only first-year students, but also parents and guardians, student leadership, and support staff from both the Bloemfontein and South Campuses.

 “I would like to congratulate each of our first-year students for making the decision to come to Kovsies to further your studies here. But I would also like to thank you for making this choice,” he continued.

Prof Petersen further emphasised that the students’ experience and success as individuals are important to the UFS as an institution; therefore, academic and support staff are on hand to guide them through their journey to becoming well-rounded individuals. “We will surely take care of you,” said Prof Petersen. He also reassured parents and guardians that their loved ones would be well looked after.

The Rector also focused attention on the role of student-leadership structures, such as the newly-formed Institutional Student Representative Council (ISRC) and South Campus SRC, members of which were present in the audience. He thanked them for playing a key role in the student constituency, highlighting their support and guidance to help first-years cultivate a sense of belonging at the UFS.

Turning back to first-year students, Prof Petersen stated that they have the unique opportunity to study on a campus specifically focused on developing their full potential, a campus where they can realise their dreams. “Your arrival on the campus marks a new chapter in your life. This chapter is slightly different, as you are the author thereof. The previous chapters in your life were largely written by others—your parents, guardians, families, teachers, and others. You will now be the main author in the next chapter of your unique story.”

“At Kovsies, we believe in developing students in their totality as human beings, not just the academic side. May your time with us equip you to make a success of your life after university!”

Prof Petersen’s Message to First-year Students
  1. Take responsibility for your academic programme.
    • Keep your focus. Study and study hard. You will reap the rewards and see the advantages of making success in your studies a top priority.
    • Make sure that you have enough time for your studies; balance your social life and your time set aside to study.
  2. Realise and remember that you are not alone.
    • If you find things difficult, seek help.
    • Our Department of Student Counselling and Development has trained staff and tailor-made programmes that can assist you.
    • Look after your mental health—and look after each other’s mental health.
  3. Make the most of your time at Kovsies.
    • Join one or more of the student organisations; why not try something new?
  4. Embrace difference and diversity.
    • Get to know students who are different from you.
    • You will lose valuable opportunities to grow if you only associate with your own all the time. It is important to get to know students who are different from you. It could be someone from a different part of the country, or from another country, a different ethnicity, a different religion, someone who has different views from yours, or who has different interests and perspectives.

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.
