Talk:Delta Crucis

Article moved from "Decrux" to "Delta Crucis"

Names of the bright stars in Orion or Ursa Major are obscure and the star articles should not be named after them... ok. But "Decrux" is far more obscure name than any of them. Therefore I moved the article here.

New Update

I have just made some new updates on this article. Updated info plus minor material with a cite. I have corrected several syntax or context errors, and rearranged the structure similar to the article on the Crux stars. Name change uses the new IAU star naming decree.

There was some uncited text claiming the variable star had a period of 1.3 hours (since 2012), but couldn't find any source to support this. Beta Cepheids usually have multiple modal periods not just one. HIP 59747 2.7066+/-0.0005 mad, and is described as a microvariable in "Hipparcos variable stars" (Adelman, et al. (2001)[1]/[2] .

Some new other errors may have been accidental introduced and may need further corrections. Arianewiki1 (talk) 00:31, 4 May 2019 (UTC)

Move discussion in progress

There is a move discussion in progress on Talk:Ginan (star) which affects this page. Please participate on that page and not in this talk page section. Thank you. —RMCD bot 14:00, 9 August 2019 (UTC)

Article title

I don't believe the article name 'Imai' satisfies WP:CRITERIA. I performed a search for the title and found almost nothing referencing the star. It should be changed to Delta Crucis. Praemonitus (talk) 20:50, 5 July 2021 (UTC)

end as a white dwarf?

If a star has a mass more than eight times of the solar mass,it will explode to supernova.And this star has about 9 solar masses,so I am doubtful about that. 超級淆底獸 (talk) 18:18, 11 September 2021 (UTC)

You are most likely correct, assuming the mass estimate is accurate. I removed the unsourced speculation. Thanks. Praemonitus (talk) 20:37, 11 September 2021 (UTC)

Imai (star) → Delta Crucis – The name Imai was adopted for this star by the IAU in 2018, but prior to that date it was always designated Delta Crucis. The new name has not yet been widely adopted, except by forks of Wikipedia. It should be restored to the original per WP:COMMONNAME. Praemonitus (talk) 19:03, 16 October 2021 (UTC)

• Support - Per nom. As pointed out above, most of the stars of the Big Dipper (Mizar excepted) are located at their Bayer names, not their traditional names. "Imai" likewise has little currency. -- Elphion (talk) 22:22, 16 October 2021 (UTC)
• Support per nom - no evidence this has become a common name. User:力 (power~enwiki, π, ν) 00:38, 17 October 2021 (UTC)
• Support per the above. ╠╣uw [talk] 12:48, 17 October 2021 (UTC)
• Support by common name of what this article refers to. Iggy (Swan) (Contribs) 09:53, 23 October 2021 (UTC)
• Oppose. Per consistency with other stars in Crux constelation. Also, no evidence has been provided to show the proposed name is more common. Vpab15 (talk) 17:35, 25 October 2021 (UTC)
