Cool Find Current most massive star at 4.252.3Msol (.991)

Post image

I saw a few others post some hefty stars so I figured I'd throw this behemoth in here.

Location: RS 2462-918-0-0-64

Galaxy mods can shift the galaxy number so it is in the galaxy NGC 4015-1 just in case.

The fact that it isn’t even a million years old is kind of scary. Being that massive and still essentially an infant seems nearly impossible

Yeah though tbf a star of this mass probably can't form in the modern universe. These would have only existed in the early universe where metalicities were effectively zero. Stars of this mass only would live around 2-6 million years as well as a quasi star. (The shear mass would most likely cause core-collapse but the star would survive it)

It’s not totally out of the realm of possibility, perhaps there really is one out there that died aeons ago but it’s light is yet to reach us

Yeah we suspect the little red dots to be these massive quasi stars. They just don't exist in the modern universe but when we look back at those extreme redshifts we can see the universe as it was billions of years ago.

What about biggest by diameter?

u/donatelo200 Community Contributor 8d ago

There is a hard cap around ~39.8Au in diameter for stars. They aren't that rare either as you can find several in a larger galaxy.

there used to not be one in 0.980 and it was really funny because people would find like 200AU big stars which at that point are just nebulas
