Images for Proxima c?

I found a possible page image for Proxima c, which is a possible direct imaging detection made by SPHERE. https://scx2.b-cdn.net/gfx/news/2020/astronomersm.jpg This artists' impression with its massive ring system could also be a page image. https://i.imgur.com/TEjSP3U.jpg TheWhistleGag (talk) 15:02, 27 September 2020 (UTC)

The image you linked looks like it's HIP 65426 b. One of the images from the direct imaging paper could potentially be used, but I'm not sure what the license for those images would be. SevenSpheresCelestia (talk) 18:58, 27 September 2020 (UTC)

It's still unconfirmed - consensus reached

Thanks for creating the article, great job. It seems this exoplanet is still unconfirmed. Most of the papers refer to it as a candidate, and it doesn't appear in the NASA exoplanet archive. However, I think it's a great idea to keep the article.

(Copied from Talk:List of Kepler exoplanet candidates in the habitable zone)

From the article: "In June 2020, the planet's existence was confirmed using Hubble astrometry data from c. 1995, allowing its inclination and true mass to be determined." I don't know why the Exoplanet Archive hasn't added it (this is the case for a few other planets as well), but the literature does support its status as a confirmed planet. However, Proxima d is a good example of an unconfirmed planet that shouldn't have its own article (unless it gets confirmed at some point). SevenSpheresCelestia (talk) 00:40, 1 October 2020 (UTC)

-- Thanks for the sources. Both seem to belong to G. Fritz Benedict, and the main one seems to be a research note rather than a paper. I haven't seen this claim supported in other papers. The article including allowing its inclination and true mass to be determined includes the word candidate in its title. The Gratton article also says we cannot confirm that our candidate is indeed Proxima c. Proxima c still seems to be unconfirmed. For an exoplanet to be confirmed, it has to be confirmed by several authors/papers. Also, this article seems to be a stub right now — Preceding unsigned comment added by Albertheditor (talk • contribs) 00:44, 1 October 2020 (UTC)

--Update: consensus was reached here https://en.wikipedia.org/wiki/Wikipedia_talk:WikiProject_Astronomy#Proxima_c_isn%27t_confirmed to still keep Proxima c as a candidate.

Consensus has not been reached yet, only one other user has commented (and didn’t explicitly agree with either side of the argument). SevenSpheresCelestia (talk) 13:59, 1 October 2020 (UTC)

Based on consensus and considering that all the 2020 papers refer it as a candidate except 1, I edited as follows: an exoplanet candidate considered to be confirmed by Fritz Benedict and Barbara E. McArthur in their research note titled A Moving Target—Revising the Mass of Proxima Centauri c
