N44 (astronomy)

 * ... that N44 (pictured), an emission nebula in the Large Magellanic Cloud, has superbubble structure due to its powerful stars?


 * Symbol question.svg Article hasn't been classified yet. It does not appear to have undergone a copyedit. I have found three errors so far. In sentence two, I believe that the number 196 should actually be the date 1956. In sentence nine, M44 should presumably be N44. Also, in the last, eleventh sentence, there should not be a red link to oxygen atoms. This should be repaired. And, since there is a substantial reliance on the first source, which is offline, the contributor should carefully review the article for any other errors that the reviewer hasn't caught.

 * Hi Anne! I've fixed the errors you mentioned and thoroughly checked against my offline source. Is there anything else I need to take care of? Thanks for the review. Keilana | Parlez ici 00:05, 8 May 2012 (UTC)
 * Symbol confirmed.svg You're welcome. Date and length fine. (Checked article class-not a stub.) Added (pictured) to hook. No overly close paraphrasing. On line sources good, photo gorgeous. (A work of art.) You're all set. Anne (talk) 19:03, 8 May 2012 (UTC)
 * Thank you so very much! Keilana | Parlez ici 19:06, 8 May 2012 (UTC)
 * Symbol question.svg I was about to move this to a prep area when I realized that one of the key facts in the hook, "has a superbubble structure due to its powerful stars", does not have an inline citation in the article, something required by the DYK rules. The only one of the online sources that uses the word "superbubble", the last, is not cited for that term. If the citation is in the Wilkins/Dunne source, then this can be accepted, but with the AGF tick. My preference would be to have at least one source cited after the first sentence, since it states all the claims in the hook except for "due to its powerful stars". However, the article does not explicitly support this contention; "radiation pressure" from the group of 40 stars and the fact that they are "blue-white and incredibly luminous" does not also say they are "powerful stars", and I don't infer that from the text. Perhaps a small word change supported by the sources could be made to the article to clarify this, or the hook could instead say "due to the radiation pressure from its stars"?

 * The superbubble fact is cited in Wilkins and Dunn; there's not an e-book on Google Books, so I can't link to it or anything. However, I found citations for it in a conference paper, a NASA blurb , and an article from the Gemini Observatory . I added them to the article and would like to change the hook to "that N44 (pictured), an emission nebula in the Large Magellanic Cloud, has superbubble structure due to radiation pressure from its powerful stars?". Is that ok? Keilana | Parlez ici 17:24, 10 May 2012 (UTC)
 * Reprinting the above hook as an official ALT for clarity (and adding "a" before "superbubble" as a grammatical fix):
 * ALT1: ... that N44 (pictured), an emission nebula in the Large Magellanic Cloud, has a superbubble structure due to radiation pressure from its powerful stars?
 * The only issue I see is that as you want the word "powerful" included, then it (or an obvious synonym) has to be in the article referring to the stars. It's definitely in the sources, so that won't be an issue (the "Roses in the Summer Sky" source, for one). Neither "blue-white" nor "incredibly luminous" convey this. The powerful winds mentioned are for N44F, not N44, so they don't apply to the hook. BlueMoonset (talk) 17:58, 10 May 2012 (UTC)
 * Thought I changed that, but didn't. Derp. It should be in the article now. Keilana | Parlez ici 18:39, 10 May 2012 (UTC)
 * Symbol confirmed.svg Hook facts are all in the article and supported by inline source citations. Thank you. Hope this gets picked up for a picture hook! BlueMoonset (talk) 20:01, 10 May 2012 (UTC)
 * Thanks for the review! I hope it gets a picture hook too; it's gorgeous. :) Keilana | Parlez ici 02:19, 11 May 2012 (UTC)
