Talk:Gacrux

message: Since there appears to be some controversy here, I thought I would throw in some background on this name. It is an invention, a coinage, which became popular only when it was adopted by the "American Nautical Almanac" when it was revised in 1953. Navigators used this name, not astronomers.  —Preceding unsigned comment added by 216.80.110.88 (talk) 01:47, 25 November 2009 (UTC)

thread_title:  the name Gacrux 

message: The article refers to Gacrux as a binary star, then goes on to explain that it's only an optical binary.  A binary star is defined in Wikipedia as "a star system consisting of two stars orbiting around their common center of mass."  This is not the case for Gacrux and the description as a binary should be removed.  Paul Fisher (talk) 11:55, 13 May 2010 (UTC)
thread_title:  Binary star? 

message: Derrr? This uncited statement, as presently worded, is nonsense. However, it's possible what is meant is that the barium is the result of mass exchange with a white dwarf companion. I'll remove the statement completely Real Soon if no one can come up with a cite. Yaush (talk) 22:38, 14 April 2011 (UTC)
thread_title:  Neutron emission from white dwarf companion? 

message: Does anyone has information on how much time is estimated until Gamma Crucis becomes a horizontal branch star? According to its radius of 84 R☉, it has almost reached the tip of a red giant branch. --Artman40 (talk) 23:17, 1 July 2013 (UTC)

thread_title:  External links modified (January 2018) 

message: I have just made some new updates on this article. Updated info plus minor material with a cite. I have corrected several syntax or context errors, and rearranged the structure similar to the article on the Crux stars. Controversy mentioned above have been mostly solved with IAU star naming decree. Some new errors may have been accidental introduced and may need further corrections.
