Adriaan Blaauw
Adriaan Blaauw (12 April 1914 – 1 December 2010) was a Dutch astronomer. Blaauw was born in Amsterdam to Cornelis Blaauw and Gesina Clasina Zwart, and studied at Leiden University and the University of Groningen, obtaining his doctorate at the latter in 1946. In 1948, he was appointed an associate professor at Leiden. In the 1950s he worked a few years at the Yerkes Observatory, before returning to Europe in 1957 to become director of the Kapteyn Astronomical Institute in Groningen. Blaauw was closely involved in the founding of the European Southern Observatory, and was its general director from 1970 to 1975. In 1975, he returned to the Netherlands, becoming a full professor at Leiden, until his retirement in 1981. From 1976 to 1979, he served as president of the International Astronomical Union. He chaired the committee for assigning scientific priorities for the observing programme of the astrometric satellite ''Hipparcos.'' His research has involved star formation, the moti ...

Stellar Kinematics
In astronomy, stellar kinematics is the observational study or measurement of the kinematics or motions of stars through space. Stellar kinematics encompasses the measurement of stellar velocities in the Milky Way and its satellites as well as the internal kinematics of more distant galaxies. Measurement of the kinematics of stars in different subcomponents of the Milky Way including the thin disk, the thick disk, the bulge, and the stellar halo provides important information about the formation and evolutionary history of our Galaxy. Kinematic measurements can also identify exotic phenomena such as hypervelocity stars escaping from the Milky Way, which are interpreted as the result of gravitational encounters of binary stars with the supermassive black hole at the Galactic Center. Stellar kinematics is related to but distinct from the subject of stellar dynamics, which involves the theoretical study or modeling of the motions of stars under the influence of gravity. Stel ...

University Of Groningen Alumni
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in the Middl ...

2145 Blaauw
2145 Blaauw, provisional designation , is a dark Ursula asteroid from the outer regions of the asteroid belt, approximately 38 kilometers in diameter. It was discovered on 24 October 1976, by astronomer Richard Martin West at the La Silla Observatory in northern Chile. The asteroid was named after Dutch astronomer Adriaan Blaauw. Orbit and classification ''Blaauw'' is a member of the Ursula family (), a large family of C- and X-type asteroids, named after its parent body, 375 Ursula. It orbits the Sun in the outer asteroid belt at a distance of 2.9–3.5 AU once every 5 years and 9 months (2,107 days; semi-major axis of 3.22 AU). Its orbit has an eccentricity of 0.10 and an inclination of 15 ° with respect to the ecliptic. The asteroid was first identified as at Lowell Observatory in December 1929. The body's observation arc begins with its identification as at the Karl Schwarzschild Observatory in September 1963, or 13 years prior to its official disco ...

Asteroid
An asteroid is a minor planet—an object larger than a meteoroid that is neither a planet nor an identified comet—that orbits within the Solar System#Inner Solar System, inner Solar System or is co-orbital with Jupiter (Trojan asteroids). Asteroids are rocky, metallic, or icy bodies with no atmosphere, and are broadly classified into C-type asteroid, C-type (carbonaceous), M-type asteroid, M-type (metallic), or S-type asteroid, S-type (silicaceous). The size and shape of asteroids vary significantly, ranging from small rubble piles under a kilometer across to Ceres (dwarf planet), Ceres, a dwarf planet almost 1000 km in diameter. A body is classified as a comet, not an asteroid, if it shows a coma (tail) when warmed by solar radiation, although recent observations suggest a continuum between these types of bodies. Of the roughly one million known asteroids, the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 astronomical unit, AU ...
