VIRAC leading researcher Juris Kalvāns has been accepted in the International Astronomical Union

May 6, 2021

Juris Kalvāns, the leading researcher of the Ventspils International Radioastronomy Centre (VIRAC), has been accepted as a full-fledged individual member of the International Astronomical Union (IAU). The IAU's objective is to further the advancement of astronomy, and it has over 12,000 members who are scientists from 106 countries. This event is a significant appraisal of the researchers' scientific achievements and a statement for the Latvian Cosmos research infrastructure, of which the primary tractive power is VIRAC.


Statutes regulate the IAU member acceptance process. To become a full-fledged individual member, the VIRAC researcher had to go through a multi-step application process and get approval from the IAU Executive Committee. Juris Kalvāns was picked as the fittest candidate by the Latvian National Committee, which, together with the University of Latvia, represents Latvia in the IAU. Juris Kalvāns has met the expected education qualifications – a doctoral degree – and has proven himself with high-quality scientific publications and work in the VIRAC. As the researcher himself admits, being a full-fledged individual member of the IAU means having the opportunity to vote on astronomical issues that influence the scientific society and each of us. The 2006 decision to remove Pluto from the list of planets is a visible example of how an IAU decision impacted what students learned about the Solar System in geography classes. Until this IAU General Assembly decision, Pluto was one of the Solar System’s nine planets; however, it is now classified as a dwarf planet, and the Solar System contains eight planets.


Latvia is represented in the IAU by 12 individual members, five of which are VIRAC leading researchers – Juris Freimanis, Boriss Rjabovs, Ivars Šmelds, Juris Žagars, and recently admitted Juris Kalvāns. Six individual members are current and former University of Latvia scientists and an IT expert and populariser of astronomy Mārtiņš Gills.

Andris Vaivads, Rector of Ventspils University of Applied Sciences, has been elected as a new foreign member of the Royal Swedish Academy of Sciences' Class for Astronomy and Space Science. Andris Vaivads studies what is commonly known as the magnetosphere around the Earth, other planets and the SunClass for astronomy and space science. He performs his research as a professor in Experimental Space Physics at KTH Royal Institute of Technology in Stockholm. Earlier, he spent 20 years as a researcher at the Swedish Institute of Space Physics in Uppsala. He studies the magnetosphere around Earth, other planets, and the Sun. Much of space is filled with plasma, a gas consisting of electrically charged particles that are influenced, among other things, by magnetic fields. When magnetic fields pointing in different directions reconnect – a process known as magnetic reconnection – large amounts of magnetic energy can rapidly be converted into other forms of energy, including kinetic energy. Andris Vaivads’s research focuses on these processes, where large amounts of energy are converted within small regions of space. Plasma processes can, among other things, produce the Northern lights (Auroras), affect satellites, and heat plasma to tens and hundreds of millions of degrees. The research group at KTH, in which Andris Vaivads spends 20 per cent of his working time, develops instruments to measure electric fields on satellites. The group also designs small measurement probes that can be launched from Esrange Space Centre in Kiruna on rockets. More recently, Andris Vaivads has also studied processes in the solar wind, a kind of plasma wind that plays a major role in space weather. This research uses observations from spacecraft launched by ESA (Solar Orbiter) in Europe and NASA (Parker Solar Probe) in the US. Members of the Royal Swedish Academy of Sciences serve on committees and participate in classes that initiate investigations, respond to consultations, and organise conferences and seminars.
