Research Consortium On Nearby Stars

The REsearch Consortium On Nearby Stars (RECONS) is an international group of astronomers founded in 1994 to investigate the stars nearest to the Solar System \- with a focus on those within 10 parsecs (32.6 light years), but as of 2012 the horizon was stretched to 25 parsecs. In part the project hopes a more accurate survey of local star systems will give a better picture of the star systems in the Galaxy as a whole.

## Notable discoveries

The Consortium claims authorship of the series The Solar Neighborhood in The Astronomical Journal, that began in 1994.[1] This series now numbers nearly 40 papers and submissions. The following discoveries are from this series:

* GJ 1061 was discovered to be the 20th nearest known star system, at a distance of 11.9 light years.[2]

* The first accurate measurement of distance for DENIS 0255-4700 . At a distance of 16.2 light years, it is the nearest known class L brown dwarf object to the Solar System.[3]
* The discovery of 20 previously unknown star systems within 10 parsecs of the Solar System. These are in addition to 8 new star systems announced between 2000 and 2005.[4]

RECONS is listed explicitly as an author on papers submitted to the Bulletin of the American Astronomical Society since 2004.[5]

The RECONS web page includes the frequently referenced "List of the 100 nearest star systems".[6] They update this list as discoveries are made. A list of all RECONS parallaxes[7] is available, as are all papers in the solar neighborhood series[8] and [9] which illustrates data from the RECONS 25 Parsec Database.
