Happy to review this article.

@Amitchell125: great! Cas Liber (talk · contribs) 10:58, 10 October 2020 (UTC)[reply]

Assessment

[edit]

Lead section / infobox

[edit]
  • Unlink arrow (common word), here and in the infobox.
  • Duplicate links – constellation; magnitude.
  • The red giant Gamma Sagittae… - I would try to separate these links out, perhaps by amending to ‘Gamma Sagittae, a red giant,…’.
  • Ditto ... cataclysmic variable binary star system… - ‘ ...a binary star system that is cataclysmically variable…’?
  • Consider linking multiple stars.
  • Link brown dwarf.

History

[edit]
  • Duplicate link – Aquila (occurs more than once).
  • ...this constellation… - the main article should introduce the constellation’s name here.
  • Link Hercules; Stymphalian birds.
  • Who is Richard Hinckley Allen?
  • Who was Eratosthenes?
  • Ref 3 (Allen) requires a page number.

Characteristics

[edit]
  • Who was Eugène Delporte?

Notable features

[edit]
Sagitta - white background
  • It could be my eyes, but the top image is very black. Do you think this inverted version of the same image, which also has better quality text (right) would work better?
  • Duplicate links – Alpha Sagittae; planetary nebula (occurs more than once).
  • Consider moving the image to the right, imo the layout then looks better.
  • Who were Johann Bayer, Friedrich Wilhelm Argelander, Heis and John Flamsteed?
  • Link chi (and add the symbol to show the similarity?); luminosity (as it has a technical meaning); arc seconds (I believe it is hyphenated, Minute and second of arc).
  • ...the spike … - I’m unclear what this referring to.
  • Does the animation work? It didn't for me...
  • This section makes quite hard reading. Looking at other articles, I saw the layout of the Stars section in Andromeda (constellation)—which is bulleted—easier to follow. I would consider the same approach. What do you think?
  • I have done many constellation articles and for most have tried them as engaging prose on a few of the most interesting objects - the idea was that there is already a List of stars in Sagitta article that orders them like a table or list. Some have come across better than others. Generally by mixing in interesting facts and omitting some more boring items. I'll take another look at this and ponder. Items have also been organised as bright stars/double stars/variable stars etc. Cas Liber (talk · contribs) 05:32, 12 October 2020 (UTC)[reply]
Alternatively, the information for the brightest stars could be tabulated, in a summarised version of List of stars in Sagitta. Would this work in your opinion?
Name B F vis.

Dist. (ly) Sp. class Notes
γ Sge γ 12 3.51 −1.11 274 K5III variable star, ΔV = 0.004m, P = 6.37836 d
δ Sge A δ 7 3.82 −1.87 448 M2II + B6 semiregular variable, Vmax = 3.75m, Vmin = 3.83m
δ Sge B δ 7 3.80
α Sge α 5 4.39 −1.42 473 G0II Sham, Alsahm
β Sge β 6 4.39 −1.39 466 G8II
ζ Sge ζ 8 5.01 0.01 326 A3V
η Sge η 16 5.09 1.61 162 K2III suspected variable
Name = Proper name  · B = Bayer designation  · F = Flamsteed designation  · vis. mag. = visual magnitude (m or mv), also known as apparent magnitude  · abs. mag. = absolute magnitude (Mv)  · Dist. (ly) = Distance in light-years from Earth  · Sp. class = Spectral class of the star in the stellar classification system
  • I did some editing on that section, which hopefully improved things. The table might fit into the bright stars sub-section that I created. Perhaps still a daunting block of text. I suggested earlier simplifying some of the error ranges, but wasn't sure what else to do. Lithopsian (talk) 14:07, 13 October 2020 (UTC)[reply]
  • Ref 23 (Redpath) is a self-published source and so cannot be used to verify the text here.
Happy with your reply. Amitchell125 (talk) 14:04, 12 October 2020 (UTC)[reply]

References

[edit]
  • The link for Ref 9 (IAU) seems to be incorrect.
  • The references for Brown, A. G. A.; et al appear to be identical, but they're not. They need to be identifiable and differentiated (using the star's identification number, for instance). The retrieval dates needs to be added too.

Checking for more.... Amitchell125 (talk) 16:14, 10 October 2020 (UTC)[reply]

I looked through all the {{cite DR2}} citations and they all have an identification number in the template. This is translated into a link to the entry for that star in the VizieR database, which shows after the conventional journal citation. The database is fixed, a copy of Gaia Data Release 2, in electronic form because it is much too big to print out in a journal paper. For this reason the template doesn't support a retrieval date.

Many thanks for that, Lithopsian. Amitchell125 (talk) 17:35, 12 October 2020 (UTC)[reply]

On hold

[edit]

I've checked some of the data and no problems came up, so I'm tempted not to check every single fact. The article is an interesting read. I'm putting it on hold for a week until 18 October to allow time for the above points to be discussed and/or addressed. Some of them are suggestions (Consider; I would, do you think), and not necessarily needed for GA level. Amitchell125 (talk) 16:47, 10 October 2020 (UTC)[reply]

Passing

[edit]

The article looks ready to pass now. I added an external link to Bayer's star maps at the Linda Hall Library, Sagitta is easily found. Great work, Casliber, and thanks for helping make the review a pleasure to do. Amitchell125 (talk) 06:28, 14 October 2020 (UTC)[reply]
