Work

Hartmut Jahreiß obtained his Ph.D from the University of Heidelberg. His thesis was on the spatial distribution, kinetics and age of stars near the Sun.[1] Jahreiß soon began work at Astronomisches Rechen-Institut with Wilhelm Gliese, a world-renowned authority on nearby stars. Jahreiß is best known for his collaboration with Gliese on the publication of new editions of the Gliese Catalogue of Nearby Stars in 1979[2] and 1991.[3] Upon the death of Gliese in 1993, Jahreiß wrote Gliese's obituary.[4] The Gliese catalog stars are now known by the abbreviation GJ (Gliese–Jahreiß) in recognition of Jahreiß's contribution.

Jahreiß contributed to the Hipparcos catalogs of nearby stars.[5] In 1997, as a member of the Research Consortium on Nearby Stars (RECONS), he identified GJ 1061, at a distance of just 3.68 parsecs, as the 20th closest star to Earth.[6]

The main-belt asteroid, 9861 Jahreiss (1991 RB3), is named in his honor.
