Biography

Raab finished his studies of computer science at the Johannes Kepler University of Linz in 1995 as a graduate engineer. In 2012, he received the Master of Science in Management for Engineers at the LIMAK business school in Linz, where he also graduated as Master of Business Administration in 2013. He works as a software engineer in the field of commercial software. [3]

In 1983, he joined the Astronomical Society of Linz (German: Linzer Astronomische Gemeinschaft), and has been president of the society from 1996 until 2017. Since 1990, he has been developing the widely used software Astrometrica, which is used for astrometric and photometric analysis of images of asteroids and comets. [4] Raab's most important observations include precise astrometry of the comet Shoemaker–Levy 9, which he observed together with Erich Meyer and Erwin Obermair in 1993. These observations have significantly contributed to the subsequent prediction of the impact of this comet on the planet Jupiter. [5]

On 10 August 1997, he discovered the asteroid 13682 Pressberger together with Erich Meyer at the private observatory Meyer/Obermair in Davidschlag (municipality Kirchschlag bei Linz, Austria). [1] [6] Furthermore, he was involved in three other discoveries of asteroids which were assigned as site discoveries to the observatory Davidschlag by the International Astronomical Union (see Category:Discoveries by the Davidschlag Observatory). [7] During the Occultation of the star HIP 76293 by the asteroid 1177 Gonnessia on 18 May 2007, Raab discovered that the star is a close double star, whose components have a separation of just 0.04". [8] [9]

In May 1996, asteroid 3184 Raab was named in his honor, following a proposal of Brian G. Marsden and Gareth V. Williams from the Minor Planet Center ( M.P.C. 27124). [2] [10] On 4 April 1997, Raab was presented the Gold Medal for Services to the Republic of Austria. [11]

His wife Agnes Raab (born 1969) is also an amateur astronomer and long-time member of the Astronomical Society of Linz. In early 2004, asteroid 49109 Agnesraab, was named after her. [12]

Johann Palisa was an Austrian astronomer, born in Troppau, Austrian Silesia, now Czech Republic. He was a prolific discoverer of asteroids, discovering 122 in all, from 136 Austria in 1874 to 1073 Gellivara in 1923. Some of his notable discoveries include 153 Hilda, 216 Kleopatra, 243 Ida, 253 Mathilde, 324 Bamberga, and the near-Earth asteroid 719 Albert. Palisa made his discoveries without the aid of photography, and he remains the most successful visual (non-photographic) asteroid discoverer of all time. He was awarded the Valz Prize from the French Academy of Sciences in 1906. The asteroid 914 Palisana, discovered by Max Wolf in 1919, and the lunar crater Palisa were named in his honour.

The OCA–DLR Asteroid Survey (ODAS) was an astronomical survey to search for small Solar System bodies focusing on near-Earth objects in the late 1990s. This European scientific project was a collaboration between the French Observatoire de la Côte d'Azur (OCA) and the German Aerospace Center (DLR). The survey is credited for the discovery of one comet and more than 1000 minor planets during 1996–1999.

The Uppsala–DLR Asteroid Survey is an astronomical survey, dedicated for the search and follow–up characterization of asteroids and comets. UDAS puts a special emphasis on near-Earth objects (NEOs) in co-operation and support of global efforts in NEO-research, initiated by the Working Group on Near-Earth Objects of the International Astronomical Union (IAU), and the Spaceguard Foundation. UDAS began regular observations in September 1999, with some test runs during 1998. Discoveries of NEOs are reported to the Minor Planet Center (MPC).
