Hot companion

The term "hot companion" is not the one used for these objects: the discovery paper uses "hot compact object" [1], which Google reveals to have been used in discussions of other systems where it is not clear whether the object is a white dwarf, neutron star or black hole, e.g. the usage in the GCVS variable star type list [2]. Furthermore subsequent study of the two objects in question reveals that, contrary to the initial media hype, they are most likely to be white dwarf stars [3], for which we already have an article. While it might be desirable to have an article about hot compact objects in astrophysics (which may or may not be in binary systems and therefore "companions"), there does not seem to be much rationale for having an article devoted to these two objects alone.

The term does not apply to these two objects alone, but is a common astronomical term for describing, well, hot companions of uncertain designation. Delete it for now though, I guess: not much there. — Aldaron • T/C 23:32, 18 June 2010 (UTC)[reply]

Looks like a term more suited to a dictionary. "Hot companion (n): (in astronomy) a component of a binary system that is hot relative to the primary"... Icalanise (talk) 23:42, 18 June 2010 (UTC)[reply]

Delete WP:NOTADICTIONARY, and if the central star is something cool, like a red supergiant, and the companion is a hotter star, like say an blue giant, then the "hot companion" is a giant star, according to the definition in the article. 70.29.212.131 (talk) 04:54, 19 June 2010 (UTC)[reply]
Comment this was previously discussed at WT:ASTRO, see the talk archive (do not reply to that section, it has been archived). 70.29.212.131 (talk) 04:58, 19 June 2010 (UTC)[reply]
