Research fields:


GAIA satellite The astrometry group at the ARI is heavily involved in the preparation of the ESA cornerstone mission Gaia, to be launched in 2011. In the recent past the ARI participated in the data analysis of ESA's HIPPARCOS satellite (1984-1997) and produced various ground-based astrometric compilations.

galaxy interaction The stellar dynamics group at the ARI performs numerical and analytical investigations of planet formation, evolution of star clusters, structure of the Milky Way, dynamics of density waves, and merging of galaxies.

Gravitational lensing At the ARI the newly founded gravitational lensing group investigates cosmological questions like the frequency of multiply imaged quasars and giant arcs, as well as aspects of microlensing, including searches for extrasolar planets.

CMD of nearby stars The ARI compiles, produces and updates a number of astronomical catalogues, like the series of Fundamental catalogues FK1 - FK6, the database of the Apparent Places of the Fundamental Stars (ARIAPFS), or the database of the Nearby Stars (ARICNS).

Magnetic field of
 White Dwarf Additionally there is a number of other research topics on special types of objects like late type galaxies, open star clusters, White Dwarfs, halo stars, and work on the calendar.
