Talk:Fomalhaut dust ring

RFD discussion: June–October 2020
Fomalhaut dust ring is a sum of parts. The literature does not consistently use that name for the ring of dust around Fomalhaut. It may be a ring, or a debris disk, or a dust ring, or a disk, depending on the author. Worth a Wikipedia page but not a dictionary entry. Vox Sciurorum (talk) 00:29, 26 June 2020 (UTC)


 * There is no entry for dust ring. Do we need one, or is this worth keeping to cover that? DonnanZ (talk) 09:37, 26 June 2020 (UTC)


 * I can't say dust ring is much more than a ring made of dust. Wikipedia uses  for the same phenomenon.  Scientific papers go either way.  An extra definition for dust might be more useful.  But definitely a definition for dust ring as a concept in astronomy would be preferable to a definition of one specific dust ring. Vox Sciurorum (talk) 11:34, 26 June 2020 (UTC)
 * The point is where dust rings commonly occur. Is it usually limited to heavenly bodies? DonnanZ (talk) 13:32, 26 June 2020 (UTC)
 * Dust ring in this sense is a purely extraterrestrial phenomenon. The physics is different on earth.  In space, the angular momentum of the dust keeps it in orbit and self-interaction tends to collapse a cloud into a disk or torus.  Vox Sciurorum (talk) 14:31, 26 June 2020 (UTC)
 * Added new sense of dust in astronomy. Vox Sciurorum (talk) 11:59, 28 June 2020 (UTC)

 * Delete per nom -- otherwise we'd potentially have to add entries for any and every astronomical body + "dust ring". Pure silliness.  However, as noted, we might benefit from creating an entry at dust ring.  ‑‑ Eiríkr Útlendi │Tala við mig 16:00, 8 July 2020 (UTC)
