HabCat (Catalog of Nearby Habitable Systems)

HabCat (Catalog of Nearby Habitable Systems) is a catalog, compiled by SETI researchers Margaret Turnbull and Jill Tarter, of star systems in the solar neighborhood that offer the best chance of supporting life on any terrestrial-type planets that may be in orbit around them. The motivation for producing the catalog was the imminent establishment of the Allen Telescope Array, which will dramatically increase the number of stars that can be systematically searched for evidence of artificial radio signals.


The first version HabCat identified 17,129 "habstars" from a set of 118,218 stars examined in Hipparcos Catalogue.
