Don't invent names on Wikipedia!

User 198.60.233.2 added a "name" Cepheidus Prototypus - besides this name being extremely clumsy, name inventions should be done on private home pages, not directly on Wikipedia. The idea as such might be a good thing, but in order to get some kind of inofficial "officialness", the name inventor should discuss with amateur astronomers (not IAU – IAU won't usually accept such proposals), and get support from there. Inofficial names may get support in some future, but please make it shorter than Cepheidus Prototypus! Said: Rursus ☻ 16:22, 27 January 2008 (UTC)[reply]

As far as I can tell, the name Cepheidus Prototypus, while not common, is occasionally used, mostly when its property of being the the prototype Cepheid variable is emphasised. I have included it along with the Arabic name and translation, and a reference to another use of this name. Inductiveload (talk) 21:58, 15 December 2008 (UTC)[reply]

My searches indicate that "Cepheidus Prototypus" seems to be an invention originating from Wikipedia, the name occurs in copies of Wikipedia and in other free net encyclopedias. Nationmaster uses a copy of Wikipedia's article on Cepheus with a list of stars that seems spurious to me. It refers to the Bright Star Catalogue, 5th Revised Ed., and the Hipparcos Catalogue, ESA SP-1200. Hipparchos does not contain "Cepheidus Prototypus", I've searched that entire catalogue for "Prototypus", I did the same for Yale Bright Star Catalogue (YBS) and found bubkes-nil-nada! The original source of "Cepheidus Prototypus" comes from some inventor at Wikipedia. "Cepheidus Prototypus" cannot really be a star name, if it were, the name should be like "Prototypus Cepheidi" or more expressively "stella vel sidus qui prototypus variabilium cepheidi est" in scientific neo-latin, a pretty clumsy language, but that doesn't make "Prototypus Cepheidi" a name, it is just a comment on the star, if there actually was such a note in a neo-latin text.

Pardon my deficient Science Neo-Latin "Prototypus Cepheidorum" or some such, it should be! Said: Rursus (☻) 09:10, 16 December 2008 (UTC)[reply]

Delta Cephei kicks over the whole cosmic distance ladder

Delta Cephei B listed as hugely massive

The table showed the mass of Delta Cephie B as 54 solar masses, which would put it at 10 times the size of Delta Cephei A, and in the supergiant category, among the biggest known stars. It's not listed in the article on the most massive stars, so I assume this is a typo. I've seen it listed on another site as 4 solar masses, but haven't been able to confirm this in any scientific journals or sites. I've hidden the size in the star data table, as I don't know how to add a comment to this table expressing doubt.

"Alrediph"

I googled the name "Alrediph" and saw that some sources cite this name as an alternative name for Delta Cephei. Is this name real? There is no mention of its name on Wikipedia pages. InTheAstronomy32 (talk) 23:39, 29 January 2024 (UTC)[reply]
