W Aquilae, an S-type star

Article Erudite and well-researched, thank you for this expert-quality contribution to the encyclopedia. New enough: expansion began June 29, nominated July 4. Long enough: readable prose from 2025 B (331 words) to 17 kB (2916 words). Minor content concerns—e.g. lack of distinction between "S stars" and "S-type stars" is unclear in lede (WP:OBVIOUS), commentary on old primary sources (e.g. "not strictly correct") sometimes appears to be WP:OR—are not disqualifying. Citations well formatted. Spot checks for close paraphrasing are all clear. Mostly cited inline, but minor problem to be resolved: §Examples cites no sources. It looks like its claims can mostly be verified by citations in its wikilinked articles, although I can't find a source for Chi Cygni being the sometime brightest S-type.

Hook Took the liberty of removing an extra ], now formatted. Hook fact is cited (to Keenan 1954), although the next sentence (cited to Boeshaar 1979) seems to unnecessarily complicate it by implying that SC-type stars (the only ones whose definitions, in that paper, allow weak or absent ZrO) are S-type stars. Not sure how interesting it is to a general readership, but it sounds intriguing and is not too technical.

QPQ Good to go. FourViolas (talk) 02:53, 5 July 2016 (UTC)

Thanks for looking at this. I think I've fixed all the concerns. I've also added a couple of images and perhaps one of them would be suitable to go with the hook. This is hardly bedtime reading for everyone, but the articles about individual S stars really needed a good definition to link to and particularly to explain the complex spectral type codes.

Concerns addressed very well. How about the above image, cropped to show more than a dot at thumbnail size, with

Image looks good. Lithopsian (talk) 21:56, 6 July 2016 (UTC)

Passed then. Only difference between hooks is "(pictured)". FourViolas (talk) 00:37, 7 July 2016 (UTC)

Several paragraphs that don't seem to be summary introductions lack any citations, per

Rule D2. Yoninah (talk) 15:17, 8 July 2016 (UTC)

Yeah, Four Violas, ya gotta get used to this idiot DYK rule that rigidly wants a cite at the end of each paragraph, whether or not that makes any sense. E Eng 22:43, 8 July 2016 (UTC) or FourViolas or whoever you are. E Eng 22:44, 8 July 2016 (UTC)

Should be done now. The only text fragments without a citation are summaries or introductions to the paragraphs that follow. Lithopsian (talk) 23:10, 8 July 2016 (UTC)

Thank you, looks good. Since hook ref is offline, restoring tick with an AGF symbol. Rest of review per FourViolas. Yoninah (talk) 20:33, 9 July 2016 (UTC)

Good call on the citations; some the the paragraphs were cited to sources other than those I had assumed. But the Bibcode link for the citation shows that the abstract opens with In this survey, spectra of type S are defined as those having bands of ZrO strong enought to be detected with low dispersion; the fulltext has Let us, accordingly, define type S by...the presence of distinct bands of ZrO in the easily observable spectral regions, after noting that this is one of two formerly widely accepted criteria.
