Any star remnant more massive than the Chandrasekhar limit, 1.4x sun mass, will become neutron star or black hole.
When you put all of this information together, we can draw a clear line between what is a star and what isn’t. If something has a collapsed core held up by radiation but is still gathering gas from a surrounding molecular cloud, it’s a protostar, not a true star. Every star of every mass will follow a different curve, but the Sun is only a star once it begins hydrogen burning, and ceases to be a star once helium burning is completed. When the mass of the neutron star surpasses the level at which the escape velocity for the neutron star exceeds the speed of light, then even light cannot escape its gravitation, thus becoming a black hole. extremely repeatable rate (most accurate clocks known at the time). Sun-like stars will blow off their outer layers in a planetary nebula, while the core contracts down to a carbon-oxygen white dwarf star, eventually fading away to become a black dwarf. they settle into a new hydrostatic equilibrium. Without achieving this, astronomers cannot consider an object to be a star.

They result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past white dwarf star density to that of atomic nuclei .
The reason is that a white dwarf is formed of relatively light elements like carbon and oxygen, so there is still a lot of thermonuclear energy available from further fusion reactions. Inside is exotic matter: superfluid neutrons, superconducting

In game, yes. Brown dwarfs range in mass from about 13 times the mass of Jupiter up to about 80 Jupiter masses: about 7.5% the mass of our Sun. When the temperature rises over about 1 million K in the core, the very first fusion reactions begin to occur. Neutron stars aren’t stars; neither are black holes, or (if they exist) any of the exotic stars like strange stars, quark stars, or preon stars. Use MathJax to format equations.
Those general fates, however — white dwarf stars, neutron stars, and black holes — represent what we know is possible. Or perhaps there are further degenerate forms of compressed matter — strange stars, quark stars, preon stars, etc. Magnetic fields on these stars can be millions of times greater than the Earth's magnetic field. in Latin. The ones that range from 7.5% to about 40% of the Sun’s mass are the red dwarf stars: they will burn hydrogen into helium and that’s it; they will never reach higher temperatures to do anything else. It's an unusual fate for a supergiant star, but these exceptional cosmic beasts do exist. MathJax reference. If something is fusing deuterium but nothing else in its core, it’s a brown dwarf star (i.e., a failed star), not a true star. Our Sun is a G-class star, producing light with an effective temperature of around 5800 K and a brightness of 1 solar luminosity. What then ensues is a race between different regions to draw in as much matter as possible. My bad , I corrected it to say star remnant.

The jets are just electromagnetic radiation released from the magnetic axis of the pulsar, caused by the extremely rapid rotation of the star.
But a neutron star is so dense that the equivalent of 1.3 solar masses fits inside an area of a city-sized sphere.
Is there a correlation between temperature, mass, and radius? Is it okay to use "It was all just a virtual world / dream" for a plot twist? There is likely a very massive planet causing these spiral features, but that has yet to be definitively confirmed.
