5x expanded by Casliber (talk). Self nominated at 06:53, 16 November 2014 (UTC).

Expanded 5x 4 days before nomination. Long enough. Neutral. Citations have some concerns below. No close paraphrasing. Interesting hook with good size, and it has inline citation. QPQ good. I'm not an expert on this but I'm trying my best to understand. So you can help educate me. Here are my concerns:

Couldn't find indication that it is a binary star system. Could you point out from the citation where it indicates that?

this source talks about Theta CrB A & B (2/3rds thru the article, "Theta DOES have a companion however" and talks of orbit etc.) Cas Liber (talk · contribs) 08:03, 19 November 2014 (UTC)

Should we say apparent visual magnitude instead to specify that it is the V band?

Couldn't find citation about 8.69 milliarcseconds

The data for that is incorporated on the SIMBAD page Cas Liber (talk · contribs) 08:03, 19 November 2014 (UTC)

Couldn't find the references on spectral types of B6Vnn and A2V. I only saw B6 and A2 in one of the references. Z22 (talk) 05:16, 19 November 2014 (UTC)

An A2 dwarf is a main sequence star and is more accurately written A2V. In the fulltext they list all the stars by their HD catalogue number, hence it is HD 138749. It is on pages 2 and 4. Star articles can be somewhat...oblique...in how you extract info from them sometimes.... :P Cas Liber (talk · contribs) 08:03, 19 November 2014 (UTC)

Thanks for the explanation. Facts checked out with the references. I made a minor edit to give a small hint to lay reader who may not be totally familiar with the subject. Other than that, this is good to go. Z22 (talk) 03:58, 20 November 2014 (UTC)

@Casliber: please provide an inline cite for the hook fact. Thanks, Yoninah (talk) 22:36, 20 November 2014 (UTC)
