Gould designations for stars are similar to Flamsteed designations in the way that they number stars within a constellation in increasing order of right ascension. Each star is assigned an integer (starting at 1), followed by " G. " (or occasionally followed directly by a "G" without a space), and then the Latin genitive of the constellation it lies in. See 88 modern constellations for a list of constellations and the genitive forms of their names.
Gould designations first appeared in Uranometria Argentina, a catalogue published in 1879 by Benjamin Apthorp Gould. Many of these designations have fallen out of use, though for many relatively bright southern stars (which are too far south to bear Flamsteed designations), Gould numbers remain the only simple designations available without referring to cumbersome catalogue numbers.
List of constellations utilizing Gould star designations
There are 66 constellations contained in Gould's numbering system (some of which also are covered partially or fully by Flamsteed numbers). Stars are listed in the appropriate lists for these constellation, as follows:
33 constellations that contain both Flamsteed and Gould numbers
33 constellations that contain only Gould numbers
Stars known primarily by Gould designations
Many of these were listed in the cross-index by Kostjuk, with their Gould numbers supplied as their supposed Flamsteed number. From this cross-index, the designations found their way into other sources, including SIMBAD. Many stars commonly known by their Gould designations are nearby stars.
