Cygnus X-1
This peer review discussion has been closed. This astronomy article concerns one of the first stellar black hole candidates to be discovered, and one of the most intensely studied. I've worked to expand and reference the content to cover the primary known facts, so now I'm hoping for some feedback. (There are a few more facts that need to be referenced [which I tagged] and I know that the page is a little lacking in the image department.) Hopefully the content is readable and not overly technical, at least for a scientifically-knowledgable viewer. I know there is always room for improvement, so suggestions will be much appreciated. Thanks!&mdash;RJH (talk) 19:18, 25 March 2008 (UTC)

First off, I'm no expert here at all. So consider this a layman's perspective! That should be a good start for you. All the best! The Rambling Man (talk) 17:30, 27 March 2008 (UTC)
 * "often abbreviated to Cyg X-1" - prove it!
 * What makes it a compact source?
 * Probably worth adding when it was discovered in the lead.
 * Avoid links in the bold in the lead per WP:LEAD (HDE 226868) - link HDE elsewhere.
 * "it become heated " - becomes?
 * "into interstellar space. The remaining" - merge these ... "...space while the..."
 * "(For comparison, the diameter of the Sun is about 1.4×106 km.)" don't like entire sentences in parentheses. Find a way of flowing this fact into the prose.
 * "on the order of " - of the order of?
 * Don't use K without explaining what it means. Easy way out is to put (K) after the first mention of Kelvin.
 * Expand AU before using it as an abbreviation.
 * Same with ly.
 * "Any matter that passes through this boundary is unable to escape." citation please.
 * "(The helium enrichment of HDE 226868's outer atmosphere may be evidence for this mass transfer. See below.)" as above and avoid "See below." - that's what we have wikilinks etc for.
 * As you said above, you need to sort out the [citation needed] tags.
 * "HDE 226868" section has lots of small paragraphs... consider merging some of them.
 * "(Red light can more effectively penetrate the dust in the interstellar medium.) " again, as above.
 * "bet against..." no need for italics.
 * Thank you for the feedback. I think I've implemented nearly all of your suggestions.&mdash;RJH (talk) 18:00, 28 March 2008 (UTC)
