In the Gliese catalog there are a bunch of prefixes, such as GJ, GI, Wo, etc. My question is do the numbers overlap ever? I tried to look it up, but nothing I could find was conclusive to me.

  • $\begingroup$ Isn't this explained by en.m.wikipedia.org/wiki/Gliese_Catalogue_of_Nearby_Stars ? $\endgroup$ – ProfRob Sep 12 '16 at 7:35
  • $\begingroup$ No, it does not specifically state that numeral designations are not repeated, nor would it be a good idea to just assume they don't especially with astronomy things considering how ludicriously dumb astronomy labeling often is. $\endgroup$ – Durakken Sep 12 '16 at 9:54
  • $\begingroup$ What do you mean "repeated"? Gl182 =GJ182, if that's what you mean. GJ reuses the Gl and Wo numbers unless stars are established as binaries. The wiki clearly states that the Wo supplement and then new stars in GJ used new numbers. $\endgroup$ – ProfRob Sep 12 '16 at 10:29
  • $\begingroup$ See also en.m.wikipedia.org/wiki/Star_catalogue#Gl.2C_GJ.2C_Wo for a summary. $\endgroup$ – ProfRob Sep 12 '16 at 10:36
  • $\begingroup$ Is GJ182 = GI182 = Wo182, etc. $\endgroup$ – Durakken Sep 12 '16 at 12:54
