It probably crossed the stable mass threshold and partially collapsed, which triggered the carbon burn. But, it's already so small and dense that this carbon burn is going at a radically accelerated rate. It's probably also fusing other elements swiftly as well and producing all manner of odd isotopes due to the electron-degenerate matter making up the original white dwarfs. Portions of its core might even be being forced into neutron-degenerate matter by the extreme pressure and density, as this is a star that SHOULD be collapsing into a neutron star by its sheer mass alone.

Centrifugal force is probably preventing its collapse, but allowing high enough temperatures to burn carbon, etc. Remember fusion is a product of pressure (density) and temperature. With enough temperature, the pressure doesn't have to be as high.
@Alondro77
Ай бұрын
@@ReggieArford The pressures are going to be outrageously high by default, as this object is the result of two stellar cores crashing together and just barely exceeding the Chandrasekhar Limit and managing not to totally collapse into a neutron star due to the sudden ignition of carbon fusing at a very high rate. The mystery is what its fate will be. Since it's straddling that mass limit, if it has enough carbon to burn as it's losing mass from its immense stellar winds, it may just sink beneath the limit and eventually simply 'go out' and become a very heavy O-Ne white dwarf, rather than undergo a supernova.

They only do that which physics dictates, and they cannot not do it! As for textbooks: Well, 2D pictures.... I can see it, but some of the stuff shown in animations are literal representations of hundreds, thousands and even millions of years, and all of the color is often added, because they exist outside of the visual range. So all that and it's freaking Awesome to see it like that to aid in understanding. Of course flat earthers and freaks who think stars are something totally different will claim "NASA faked it" when I would say "Hell yeah they did! How else could they make invisible light or a fine particle cloud that otherwise just looks like a gray smudge or something out of focus, visible and exciting so you can better wrap your head around it?"

I would like to be the very first to predict the existence of the Reusserburg certainty principle. This predicts that the more people expect that a given specific star will explode into a Nava or Supernova the less likely that even is to occur. The probability of a supernova occurring is inversely proportional to the number of people watching for it. This is a variation of the watched pots and boiling family of stupid sayings.

problem is no side is sure if they are right. Betelgeuse could have been supernova, but because light doesn't go faster as c, we will only notice when the 'supernova light' reaches us. At this moment everybody who says Betelgeuse has gone supernova could be right, and everybody who says it hasn't could be right too. I'm not sure if more people watching Betelgeuse think it has gone supernova (which in your statement means it hasn't) or if more people think it hasn't ( which would imply it has, according to your Reusserburg certainty principle). Matter of fact is our human life spans do not compare to these astronomical timescale. (which leaves a lot of room for grifters and people who just say something because they're influential in their group and no one can say for sure they're wrong)
