This should really be rationalised and certainly the category needs to be at least as complete as any list we make in this article. The list of galactic stars confirmed as LBVs is really very short at about a dozen and could easily go in the article. Then there are a handful more in other local group galaxies. The list of candidate LBVs, stars very likely to be LBVs but not studied long enough or in enough detail to be positive, is perhaps a bit too long and most are meaningless numbers from IR and X-Ray surveys, but a few certainly deserve mention.
271:"Hypergiants should not be confused with luminous blue variables. A hypergiant is classified as such because of its size and mass loss rate, whereas a luminous blue variable is thought to be a massive blue supergiant going through an evolutionary phase where it loses a large amount of mass." - page on Hypergiants. "Luminous blue variables...are very bright, blue, hypergiant variable stars" - LBV I don't have any expertise in the area to correct it, but this seems a blatant contradiction that would be worth bringing up. 734:@Skinsmoke - agree that all astronomy content omits the word "star" - some others when dealing with a more general audience use "star" but it is more as a descriptor appended to a title rather than titular itself - hence "Luminous Blue Variable star" (note capitalisation absence of last word) - given that our article will have the word "star" in the first sentence and lots of other immediately obvious references that it is one, I don't think omitting the word "star" in the title will confuse anyone...... 42: 495:. One comment, in the astronomical vernacular, "star" is omitted because the subject of conversation is already established as stars. In Knowledge (XXG) article titles, that isn't established. So consider my support weak - I'd prefer it because I also am used to seeing LBV without the "star", but it's not clear it is necessarily clearer for a non-astronomical audience. I notice that Red Giant and White Dwarf don't have the "star" at the end, but both require disambiguations. 174: 210: 102: 75: 33: 780: 112: 290:
I think that the term hypernova is used improperly. Saying "If they were any larger, their gravity would be insufficient to balance their radiation pressure and they would blow themselves apart in a hypernova" implies that super Eddington luminosity is the direct cause of a hypernova. This is not

There is a list in the article of what are described as "some of the best known" LBVs. Most of them are not especially well known at all, but the list is far from a complete list of all LBVs. There is also a Knowledge (XXG) category for LBVs which is even shorter than the list in this article.

when addressing a more general public, and to omit it when addressing astronomists and physicists. Perhaps the proposer would like to delve a little more deeply to see whether this move is justified. Right now I'm in the middle of something and haven't got the time to do a detailed analysis.

Even though they might not be able to tell you exactly what they are, if you stopped a person in the street and asked them what those two are, they would probably answer 596:. I do not think that if you stopped a person in the street and asked them what "white dwarf" means, they would answer "a star". More likely answer would be some mythological character. However all this is irrelevant. 536:: I'd be a little cautious with this one. We are required to make sure that article titles actually mean something to the reader, so they have a fair idea what to expect when they arrive at the page. They should 291:
the case. A hypernova marks the death of the most massive stars following the collapse of the core into a black hole. This doesn't have anything to do with a large luminosity blowing off the stars outer layers.
429:– In nearly all fields, these stars are known as luminous blue variables (LBVs) and are not specifically called luminous blue variable stars, since that is tacitly implied (as all LBVs are stars). Therefore, 837:
I don't think either the article or the list is currently too long. Yet the list is likely to expand in length (and perhaps width?) and already a good chunk of the entries are really not that interesting.
