Effect of rotation eg on core-collapse or GRB

Can we say anything on how the rotation rate of the progenitor might affect core-collapse supernovae, eg. might it affect the strength or beam open angle of a GRB ? - Rod57 (talk)

Do you have any WP:RS pertaining to that information? if you post it , an editor might look further into it.MaximusEditor (talk) 01:35, 28 January 2021 (UTC)

Pick a spelling

The article contains a mix of British and American spelling-isms. The general rule is to pick one and stick to it, going with the predominant spelling style unless there are compelling reasons otherwise. What do people think is the predominant style at the moment? Lithopsian (talk) 19:38, 2 September 2020 (UTC)

I say this as an American - I strongly believe the entirety of Wikipedia should be converted to "British" spelling (which is a bit of a misnomer; the same spelling is used in Australia, New Zealand, Canada, and the rest of both the English-speaking world and most of the rest of the world when writing in English.) The majority of the world's English speakers spell it "colour" and "realise". (While on the topic, I'd also like to see Imperial measurements expunged from science-based articles!)

However, if the general rule is to pick one and stick with it, I'd go with whichever spelling convention is currently in the majority of the article. Khardankov (talk) 13:58, 27 November 2020 (UTC)

Standardized (sic) in British spelling and tagged. Might be more to fix. 2A02:C7F:7428:D200:D41E:8807:3458:2B32 (talk) 13:58, 28 November 2020 (UTC)

Old galaxies

Under "Current Models", it is mentioned that "older, more distant" galaxies have lower metallicity. I find this use of "older" confusing. Surely, it is younger galaxies that have low metallicity, and distant galaxies are young galaxies as we see them now? Sure, distant galaxies will be old by the time we see them, if they're even still around, but that's not relevant to the context, right? Acquirium (talk) 18:36, 21 October 2020 (UTC)

WP:URFA/2020

There is very significant uncited text in this article. If this is not addressed, a featured article review may be needed. Hog Farm _Talk 17:48, 22 February 2021 (UTC)

I agree with Hog Farm's assessment above. There are lots of areas that have uncited text, and there are also some short paragraphs that should be better formatted. Is anyone willing to address concerns, or should we prepare this article for an FAR? Z1720 (talk) 19:12, 6 February 2022 (UTC)

Electron-capture supernovae 2018zd

We have a type III supernova now. I think we should separate Type III into it's own section and cover 2018zd. paper, Anton Petrov youtube video Daniel Santos (talk) 17:16, 9 July 2021 (UTC)

Stellar mergers

As reported below, another cause seems to be merger of a large star and a neutron start or black hole. Is this in the article ? (It's very long, & I haven't time to read every paragraph). <https://www.popsci.com/space/rare-supernova-merger-observed>

Steady State Universe

In a Steady State Universe, stellar explosions must be conserved. The same star explodes over and over again. It somehow quickly gains enough mass to overwhelm the energy-mass equilibrium of the star, meaning the star builds up energy-mass until the star explodes. Equilibrium is thereby regained, the mass ejected from the explosion eventually falls at once back into the star, and the runaway instability repeats itself. I assume that the expansion of mass powers stars not fusion reactions, which are incompatible with Steady State. (This expansion is relatively non generalist).GuildCompounder (talk) 21:07, 1 November 2021 (UTC)
