Location of Gliese 588 in the constellation Lupus |
Gliese 588 is a nearby red dwarf star of spectral type M2.5, located in the constellation Lupus at 19.34 light-years from Earth.[1] It emits a very stable light flux, with no detectable pulsations.[6]
History of observations[edit]
According to Luyten's (1979) (catalogue LHS, as well as NLTT), this object was discovered by Innes.[8][9] In 1903–1927 Innes was the director of the Union Observatory (UO), South Africa.
However, in the Ci 20 catalogue (see number 934) this star was designated as "CD -40 7021", not "UO".[10] This may indicate that GJ 588 was first catalogued earlier, in the Cordoba Durchmusterung by John M. Thome in 1894.[11][12] Note: the real CD designation of Gliese 588 is "CD-40 9712",[13] not "CD -40 7021":[10] GJ 588 has a RA of 15 hours, but the real CD -40 7021 has a RA of 11 hours.[14][11]
Planetary system[edit]
On 11 June 2019, two planets were detected by radial velocity around Gliese 588 among other 118 planets around M dwarf stars.[15]
