Nuclear fusion in stars? As the stars produce light thru fussion isnt its mass lost due to mass defect?

Question

So when a star dies would it experience a great mass loss , therefore would have less gravity against what is alluded that a black hole possess? how can that happen?

Answer 1

Remember the equation E = mc^2?

You don't need to lose much mass to gain lots of energy. Yes it does lose mass, but the loss is negligable compared to what mass it has.

And when you refer to star death, you seem to think stars only die in supernovas then become black holes. Stars can die an many ways. Our sun for example will become a Red Giant, then a White Dwarf, then eventually a Brown or Black Dwarf. No big nasty explostions required.

As for supernovas yes there is mass loss, quite a bit of mass loss, but if the star had between 20 to 45 times the mass of the sun the recoil could be enough to crush the remaining mass small enough to create a black hole. If the star was more then 45 times our sun's mass, it can skip the supernova stage and just go straight to Neutron Star, Pulsar, or Black Hole.

Answer 2

The life cycle of a huge call relies upon on the complicated stability between gravity which has a tendency to interrupt down the great call and means production which counteracts this tendency, yet in turn relies upon on precisely what fission or fusion methods are happening. because of the fact there are diverse great call hundreds and diverse great call composition of components, there would nicely be a great style of stellar histories basically like there are all varieties of snowfakes. a huge call in no way reaches the point of being "thoroughly burned up", onerous all count. lengthy in the previous that occurs, adjustments interior the great call reasons gravity to ultimately win out, and the great call collapses right into a dwarf great call, or a neutron great call, or each so often, a black hollow. each so often there's a impressive explosion in the previous the best fall down, that's a supernova. yet after all, there is often lots of mass left in it.

Answer 3

Hi. All stars lose mass as they form heavier elements. But a black hole is not caused by just gravity, it's caused by CONCENTRATING gravity into a small radius.
