To what does the "AP" refer in AP Columbae? Is this the Bayer designation? Norman21 (talk) 03:46, 13 September 2011 (UTC)[reply]

It's a variable star designation. Fivemack (talk) 07:43, 14 September 2011 (UTC)[reply]

OK, but that would mean the star's apparent magnitude would have to vary, and the article doesn't mention this. Norman21 (talk) 10:53, 15 September 2011 (UTC)[reply]

The star is a UV Ceti-type flare star (see arxiv article 1108.5318) Fivemack (talk) 17:44, 20 September 2011 (UTC)[reply]
