 The Astronomisches Rechen-Institut The ARI has a rich history.[1] It was founded in the year 1700 in Berlin-Dahlem by Gottfried Kirch. It had its origin in a patent application by Frederick I of Prussia, who introduced a monopoly on publishing star catalogs in Prussia. In 1945 the Institute was moved by the Americans nearer to their headquarters in Heidelberg. Since January 1, 2005 the ARI has been integrated into the Zentrum f r Astronomie (ZAH). The other two institutes in the ZAH are the Institut f r Theoretische Astrophysik (Institute for Theoretical Astrophysics, ITA) and the Landessternwarte Heidelberg-K nigstuhl (Heidelberg-K nigstuhl State Observatory, LSW). The ARI has been responsible among other things for the Gliese catalog of nearby stars, the fundamental catalogs FK5 and FK6, and the annually-published "Apparent Places of Fundamental Stars" (APFS),[2] stellar ephemerides that provide high-precision mean and apparent positions of over three thousand stars for each day. Today, the ARI is not limited to publishing star catalogs but has a wide research scope, including gravitational lensing, galaxy evolution, stellar dynamics, and cosmology. The ARI is also involved in space astronomy missions including GAIA. The current co-directors of the ARI are Eva K. Grebel and Joachim Wambsgan .
