GA Review[edit]

GA review – see WP:WIAGA for criteria This is a promising article, but there are several major issues that need to be addressed before receiving GA status.

  1. Is it reasonably well written?
    A. Prose quality:
    Some of the prose is a bit awkward, particularly the prevalence very short sentences. I've fixed some of them, but it needs some careful copyediting (probably best to wait until the other issues are dealt with first)
    B. MoS compliance:
    I split the info on the name out of the lead, since it is not a summary of what is below. Feel free to change or add to the nascent section. It certainly needs a reference though! The lead could do with an extra paragraph or so to properly summarise the rest of the article.
  2. Is it factually accurate and verifiable?
    A. References to sources:
    Sources appear to be reliable. A few personal websites of astronomers are less so, but none are for contentious statements and the sites in question seem to be written by experts. The Hersiod reference could do with a link to an online version.
    B. Citation of reliable sources where necessary:
    I've added ((cn)) tags where I think further references are required. Several of the sources are out of date, see below.
    C. No original research:
    No issues I can see.
  3. Is it broad in its coverage?
    A. Major aspects:
    Major areas are covered, but in some cases important facets are missing. See comments below for areas where I think this needs improving.
    B. Focused:
    The Mythology section rambles somewhat, and doesn't say much about the 'Ethnological impact' 'of this star. Most of the information in this section seems to belong in the Pleiades (star cluster) article, rather than here.
    Is it really necessary to have such a long description of an illustration in a work of fiction? I'm not sure this adds much to the article.
  4. Is it neutral?
    Fair representation without bias:
    No bias I can see.
  5. Is it stable?
    No edit wars, etc:
    Seems fine.
  6. Does it contain images to illustrate the topic?
    A. Images are copyright tagged, and non-free images have fair use rationales:
    File:M45map.jpg is missing author information, and might not qualify as PD-NASA due to ESA and AURA authorship
    File:Achernar.jpg has no source information
    File:HD 113766 circumstellar disk.jpg is tagged as PD-NASA, but has the credit line 'NASA/JPL-Caltech/JHUAPL' ie. not just NASA
    Note all of these are images whose appropriateness is discussed below
    B. Images are provided where possible and appropriate, with suitable captions:
    The image in the infobox is not particularly clear, and has HST fields-of-view overlaid, for no apparent reason. Since this is such a commonly-imaged cluster, I'm sure you can find a blank image and add a big arrow or circle around Pleione.
    Using an illustration of Archenar on a page about Pleione is confusing. At the very least you should make it very obvious that the image does NOT show Pleione; even better would be to find a better illustration. The same issue exists with the picture of HD 113766.
    File:Taurus constellation map.png should be changed to File:Taurus constellation map.svg
    Information is important to the article must be given in the prose, not just the captions (both would also be fine).

Discussion of GA Review

General observations

Well, I'm a professional astronomer, though my expertise is in the interstellar medium not hot stars. I'm also probably quite a tough GA reviewer :p. I'm happy to help with any technical questions you have, although I should emphasise that I'm not an expert on stars! Modest Genius talk 22:41, 13 September 2010 (UTC)[reply]
That's great! I would very much appreciate the help.--Sadalsuud (talk) 22:59, 13 September 2010 (UTC)[reply]

Prose

A. Prose quality

B. MoS compliance

Sounds sensible to me. Modest Genius talk 22:23, 13 September 2010 (UTC)[reply]

C. Lead Section

Accuracy and Verifiability

A. References to sources

B. Citation of reliable sources where necessary

Coverage

A. Major aspects

B. Focused

One or two sentences seems the best option. Even better would be to identify any other mentions in fiction to broaden the section out, though that's easier said than done! Modest Genius talk 22:23, 13 September 2010 (UTC)[reply]
I'll do some research and see if I can find anything else that could compliment this section. Another solution might be to expand the sub-section by calling it "Modern legacy" instead of "Fiction". I'll see what I can find and modify the section accordingly.--Sadalsuud (talk) 23:14, 13 September 2010 (UTC)[reply]
OK, the section "Fiction" has been renamed to "Modern legacy" and condensed into a couple of sentences. I think it works. In the next few days, I'll see if there is any more "modern legacy" stuff that would be appropriate here.--Sadalsuud (talk) 12:56, 15 September 2010 (UTC)[reply]

Neutrality

OK here.--Sadalsuud (talk) 12:30, 12 September 2010 (UTC)[reply]

OK, I'm happy to believe that. Obviously it's me that was wrong! Modest Genius talk 22:23, 13 September 2010 (UTC)[reply]

MParallax (Hipparcos)

Ah, this is where I forget not everyone knows the easy ways to find this sort of info! The 1997 data [3] are π=8.42±0.86mas, whilst the 2007 data [4] are π=8.54±0.31mas. In distance terms, that makes the 2007 determination 117±4pc. The 2009 van Leeuwen paper can be accessed for free at [5]; it's a pretty dense read even for an expert, but the relevant stuff is in section 6.3. The overall measurement for the whole cluster (using all the stars measured) is 120.2±1.9pc and I'm inclined to believe the Hipparcos result. Modest Genius talk 22:23, 13 September 2010 (UTC)[reply]
New Hipparcos estimate included. Thanks for all the help on this section. You'll notice that the new astrometric solution is included in the starbox, and the final Visibility paragraph updated accordingly. I've tried to respect Wikipedia's NPOV guidelines by presenting various viewpoints and not making any determination as to which distance estimate is the right one! I also noticed that the Pleiades article has sided with the 440ly estimate, while failing to include the 2009 paper that you have referenced. Consequently, I've tried to avoid any conflict with this "senior" article while simultaneously providing a balanced viewpoint. It might be worthwhile, once all the edits are completed here, to attempt a rewrite of the Pleiades distance section, as readers will likely crosslink to it. Your thoughts on this would be helpful.--Sadalsuud (talk) 11:26, 14 September 2010 (UTC)[reply]

Spectral classification

SIMBAD takes the SpT from a combination of references. For this star, the individual measurements used and their bibcodes are:
 |ds/mss|           Spectral type            |     reference     |
 -----------------------------------------------------------------
m|P /   |B7p                                 |1959ApJ...130..159O|
 |P /   |B8pvar                              |1956ApJ...123...54M|
 |P /   |B8pvar                              |1956ApJ...123..440S|
 |P /   |B8pvar                              |1953ApJ...118..370J|

The 5th (latest) edition of the Bright Star Catalogue gives B8Vpe, which is what I suggest you use (reference at [6], online query form at [7]). Modest Genius talk 22:44, 20 September 2010 (UTC)[reply]
B8Vpe is what appears in the starbox. However, given that SIMBAD is a highly referenced source, both for this article and in general, I thought it would be useful to clarify any confusion in the Visibility section relating to SIMBAD's use of B8IVev. Does that work?--Sadalsuud (talk) 13:56, 21 September 2010 (UTC)[reply]

Thanks for those responses, looks like things are moving along nicely. I've added a couple of comments in your text above. Modest Genius talk 22:23, 13 September 2010 (UTC)[reply]

Second look

Right, I've finally managed to have another look through and have fixed a few minor things myself. Referring back to the original review, I'm striking out things that have been sorted, and leaving comments on those that still need to be looked at:

GA review – see WP:WIAGA for criteria This is a promising article, but there are several major issues that need to be addressed before receiving GA status.

  1. Is it reasonably well written?
    A. Prose quality:
    Some of the prose is a bit awkward, particularly the prevalence very short sentences. I've fixed some of them, but it needs some careful copyediting (probably best to wait until the other issues are dealt with first)
It's still not brilliant, and I fixed several more poorly phrased sentences, but it's good enough for GA.
  1. B. MoS compliance:
    I split the info on the name out of the lead, since it is not a summary of what is below. Feel free to change or add to the nascent section. It certainly needs a reference though! The lead could do with an extra paragraph or so to properly summarise the rest of the article.

    B. Citation of reliable sources where necessary:
    I've added ((cn)) tags where I think further references are required. Several of the sources are out of date, see below.
There are now three ((cn))s and one unreferenced section.
  1. C. No original research:
    No issues I can see.
  2. Is it broad in its coverage?
    A. Major aspects:
    Major areas are covered, but in some cases important facets are missing. See comments below for areas where I think this needs improving.

    Note all of these are images whose appropriateness is discussed below
File:Fat Jon - Hundred Eight Stars.jpg does not have a fair use rationale for use in this article.

Some of these are still missing e.g. in Note 1, just after being described as a Gamma Cass variable etc.

Summary: Sort out the ((cn))s, unreferenced section (can grab a ref from the main article there), File:Fat Jon - Hundred Eight Stars.jpg and the remaining magnitudes and you're done. Modest Genius talk 19:13, 1 October 2010 (UTC)[reply]

Response to second look

Made all the changes you recommended. I imported a sailing pic to replace the File:Fat Jon - Hundred Eight Stars.jpg, putting the latter where it belongs. The sailing pic fits well, I think, with both the mythology and etymology sections too. I studied each of your edits. Thanks. It's very helpful to have an astronomer like yourself looking over this information. One last thing: I stepped back and read the article from the beginning attempting to improve the prose where possible. Several sentences have changed. Hope it works better.--Sadalsuud (talk) 17:13, 8 October 2010 (UTC)[reply]

OK, that looks good to me, I've listed the article as a GA. I'm supposed to encourage you to review an article from WP:GAN yourself, though that's entirely optional. Congratulations! Modest Genius talk 19:01, 8 October 2010 (UTC)[reply]
Thanks again for your invaluable contribution to this whole process. Being new to Wikipedia, I had no idea I could even do something like this. I should also mention that User:Casliber was the one who originally suggested I submit this article for GA Review; without his insights and support, nothing would have happened here. I'll also look at WP:GAN, although my first commitment will be to focus on the Betelgeuse article and submit it for GA review. I'd certainly welcome your input there, if you can spare the time. Anyway, I hope to get that submitted in the next few days.--Sadalsuud (talk) 05:09, 9 October 2010 (UTC)[reply]
