Hartmut Jahreiß is a German astronomer associated with Astronomisches Rechen-Institut specializing in the study of nearby stars.
. 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 and 1991. Upon the death of Gliese in 1993, Jahreiß wrote Gliese's obituary. The Gliese catalog stars are now known by the abbreviation GJ (Gliese-Jahreiß) in recognition of Jahreiß's contribution.
Jahreiß remains very active in the cataloging and study of nearby stars, preparing the new Hipparcos
catalogs, among other activities. 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.
The main-belt asteroid, 9861 Jahreiss
(1991 RB3), is named in his honor.
