Klaas de Boer (astronomer)

from Wikipedia, the free encyclopedia

Klaas Sjoerds de Boer (* 1941 in Groningen ) is a Dutch astronomer and astrophysicist and professor at the University of Bonn . For his research he used measurements obtained with satellites and terrestrial telescopes.

Life

De Boer studied astronomy and physics at the University of Groningen . In 1974 he received his doctorate in Groningen with Stuart Pottasch on Interstellar Absorption Lines in the Ultraviolet .

From 1974 to 1977 he worked at the Institute for Space Research at the University of Groningen, from 1978 to 1981 he was a research associate at the Astronomy Department of the University of Wisconsin (USA) in Madison. Between 1981 and 1985 he was a research assistant at the University of Tübingen and in 1985 he was also stationed in the same position at the University of Groningen for the cooperation between the Netherlands and Great Britain in La Palma and at the Royal Greenwich Observatory in Herstmonceux , England . Research stays took him to the Astronomy Department of Princeton University (USA) and to the University of Canterbury in Christchurch (New Zealand).

In 1986 he was appointed professor of astronomy at the observatory of the University of Bonn as the successor to Hans Schmidt .

In 2007 he retired.

Research and Teaching

Main research areas: interstellar gas, horizontal astronomical stars, kinematics in the galaxy, structure of the magellanic clouds and dwarf galaxies, areas that have as a leitmotif investigations into the three-dimensional structure of the local universe .

Together with students, doctoral candidates and local and foreign colleagues, he produced more than 250 publications, around half of which were in refereed journals. He organized various conferences, was the editor of several conference proceedings and published books. There are also more than 25 articles written for laypeople and almost 30 essays on astronomy on the Internet.

He found holding lectures and looking after his students an important and fulfilling task of his profession. He gave countless scientific lectures at home and abroad as well as several lectures for laypeople.

Commission work

Klaas de Boer was a member and chairman of various commissions, including the International Ultraviolet Explorer Program Committee of the ESA (1986–1994), the expert committee for collaborative research on astronomy and astrophysics of the DLR (1991–1993 and 1995–2001), the Science Advisory Group of the Gaia- Projekt (1998–2000) and the Board of Directors of the international journal Astronomy & Astrophysics (2001–2011).

He worked with his colleagues in Bonn to ensure that in 2006 the observatory merged with the Radio Astronomical Institute and the Institute for Astrophysics and Extraterrestrial Research to form the joint Argelander Institute for Astronomy (AIfA).

He wrote more than 250 scientific publications from 1972 to 2017. Summaries are available from ADS.
