Betelgeuse B?

arXiv:2408.09089, not yet accepted for publication but something to keep an eye on. SevenSpheres (talk) 16:57, 20 August 2024 (UTC)[reply]

Nice. 21 Andromedae (talk) 17:00, 20 August 2024 (UTC)[reply]

And now a second preprint supporting a companion to Betelgeuse. SevenSpheres (talk) 02:24, 18 September 2024 (UTC)[reply]

Mass of Betelgues

How can beetlejuice have a radius 640 times that of the sun and only 10 to 20 times the mass of the Sun? 2600:8802:B0D:4300:AD95:9A5C:B03A:C3E7 (talk) 06:06, 26 August 2024 (UTC)[reply]

That is because Betelgeuse is a red supergiant, a star in the last stages of evolution. See stellar evolution. 21 Andromedae (talk) 15:26, 26 August 2024 (UTC)[reply]

Binary companion!

In a paper with a draft on 20 August 2024 “A Buddy for Betelgeuse: Binarity as the Origin of the Long Secondary Period in Orianis“ (arXiv:2408.09089) Goldberg et al propose that Betelgeuse has a binary companion of approximately 1.2 solar masses. Not sure where best to edit this into the article. 2600:1700:466A:A100:F482:9C8C:D5B1:25F4 (talk) 05:18, 30 August 2024 (UTC)[reply]

Beteigeuze

Similar pronounciation, same topic, but a stellar system. Please clarify. 2003:E6:4F0D:2D00:3643:16D0:F793:4156 (talk) 19:09, 15 October 2024 (UTC)[reply]

It is the German spelling of the star name. See de:Beteigeuze. StarryGrandma (talk) 21:42, 15 October 2024 (UTC)[reply]

Spelling and pronunciation

From the Spelling and pronunciation sub-section in the Ethnological Attributes:

"/ˌbɛtəlˈɡɜːrz/ BET-əl-GURZ – Martha Evans Martin, The Friendly Stars[200]

"The -urz pronunciations are attempts to render the French eu sound; they only work in r-dropping accents."

What Martin actually wrote was:

"Bet-el-gerz ́ "

Martin gave no key to the pronunciation, so the interpretations given in both IPA and English Respelling appear to be individual research at best, and possibly pure speculation. The statement about r-dropping accents may very well be true, but it is not supported by any citation. So I intend to delete the pronunciation, because it's not found in the cited reference, and the comment because it's uncited and has no relevance once the pronunciation is deleted.

Any objections? After about a week, if there are no valid objections, or actual citations in support of the material, I will delete it. 172.56.194.177 (talk) 22:57, 26 January 2025 (UTC)[reply]
