Wikipedia:WikiProject Deletion sorting/Astronomy

WP:DSASTRO

This is a collection of discussions on the deletion of articles related to astronomy. It is one of many deletion lists coordinated by WikiProject Deletion sorting. Anyone can help maintain the list on this page.

Adding a new AfD discussion

Adding an AfD to this page does not add it to the main page at WP:AFD. Similarly, removing an AfD from this page does not remove it from the main page at WP:AFD. If you want to nominate an article for deletion, go through the process on that page before adding it to this page. To add a discussion to this page, follow these steps:

Edit this page and add {{Wikipedia:Articles for deletion/PageName}} to the top of the list. Replace "PageName" with the relevant article name, i.e. the one on the existing AFD discussion. Also, indicate the title of the article in the edit summary as it is particularly helpful to add a link to the article in the edit summary. When you save the page, the discussion will automatically appear.
You should also tag the AfD by adding {{subst:delsort|Astronomy|~~~~}} to it, which will inform editors that it has been listed here. You may place this tag above or below the nomination statement or at the end of the discussion thread.

There are a few scripts and tools that can make this easier.

Removing a closed AfD discussion

Closed AfD discussions are automatically removed by a bot.

Other types of discussions

You can also add and remove other discussions (prod, CfD, TfD etc.) related to astronomy. For the other XfD's, the process is the same as AfD (except {{Wikipedia:Miscellany for deletion/PageName}} is used for MFD and {{transclude xfd}} for the rest). For PRODs, adding a link with {{prodded}} will suffice.

Further information

For further information see Wikipedia's deletion policy and WP:AfD for general information about Articles for Deletion, including a list of article deletions sorted by day of nomination.

Notability/importance still seems low. No useful references to support most content on this page. Redirecting wouldn't be a bad idea. Revirvlkodlaku (talk) 00:38, 8 April 2025 (UTC)[reply]

Proplyd 133-353

Fails WP:NASTRO, has no substantial coverage beside the discovery paper. 21 Andromedae (talk) 20:18, 17 March 2025 (UTC)[reply]

Comment: on SIMBAD it appears to be catalogued as COUP 540. But yes, there's nothing in the way of additional useful resources. Nowhere in the paper does it say this is a likely sub-brown dwarf; all it says is that "Proplyd 133-353 could be a planetary-mass object". Praemonitus (talk) 22:23, 17 March 2025 (UTC)[reply]
Keep. I see two usable sources. [1] where it is initially catalogued and [2] where it is discussed in depth. The abstract of the latter says "[According to our data,] Proplyd 133-353 is substellar (∼M9.5) and has a mass probably less than 13 Jupiter mass and an age younger than 0.5 Myr." I think that even if one detailed paper is deemed insufficient it should be merged into Theta1 Orionis C or Trapezium Cluster. — Preceding unsigned comment added by Eluchil404 (talk • contribs)

Merge: The topic is too narrow for a standalone article. Proplyd 133-353 is discussed in a meaningful way in only one scholarly source (Fang et al., 2016). A JSTOR search returns 0 results, and a Google Scholar search has only two additional papers with passing mentions. Per WP:NOTABILITY, this does not justify a separate article. Recommend merging into the broader article on Proplyd as an example. HerBauhaus (talk) 07:13, 28 March 2025 (UTC)[reply]

Merge to Theta1 Orionis C -- seems like this is only discussed in 1 source, but the content is probably worth adding to the article on the star, or the article on the cluster. I assume Theta1 Orionis C is the article on the star it orbits? It seems better to have it on the more specific star article than the cluster article. Mrfoogles (talk) 01:33, 29 March 2025 (UTC)[reply]

It might warrant a mention on proplyd, but probably not much of the content can be merged there, as it's not a very exemplary example. Mrfoogles (talk) 01:34, 29 March 2025 (UTC)[reply]

I would recomend merging to Rogue planet#List 21 Andromedae (talk) 11:30, 29 March 2025 (UTC)[reply]

Nope, actually Theta1 Orionis C is the central star of the region where Proplyd formed, not the star where it orbits. Note that Proplyd 133-353 is in a young (a few miliion years) region of active star formation. A redirect to Proplyd seems more appropriate. 21 Andromedae (talk) 11:29, 29 March 2025 (UTC)[reply]

Relisted to generate a more thorough discussion and clearer consensus.
Relisting comment: Relisting. We have 3 or 4 different target articles suggested for a Merge and we have to get consensus on one primary one.
