- It's there, as α Crv. There are several paragraphs of text devoted to it although it isn't one of the program stars. Lithopsian (talk) 21:20, 10 December 2016 (UTC)
Brown Dwarf Companion
Gaia EDR3 Confirms a Red Dwarf Companion of the nearby F1 Star HD 105452 and Reveals a New Brown Dwarf Companion of the M4.5 Dwarf SCR J1214-2345 There are 88 stars which lack colors, but have measured parallaxes in Gaia EDR3 that place them within 20 pc from the Sun. Among them we found two new common parallax and proper motion (CPPM) companions separated from their primaries by about 3". The CPPM companion of a nearby (d = 14.98 pc) F1 star, HD 105452 B, was already imaged with the Hubble Space Telescope and is now confirmed with Gaia data and photometrically classified by us as M4 dwarf. The other CPPM companion, SCR J1214-2345 B orbiting an M4.5 dwarf at d = 10.77 pc, represents the faintest brown dwarf discovery made by Gaia so far. It was also imaged by the VISTA Hemisphere Survey and partly detected in the near-infrared. Our photometric classification led to an uncertain spectral type of T1 ± 3 and needs to be confirmed by spectroscopic follow-up.
