Sirius A does not have enough mass to become a supernova. It will end it's life as a white dwarf.
Highly unlikely in our lifetime. Altair is still on the main sequence and probably has a few billion years left on it. Even when it comes to the end of the main sequence, it may not have enough mass to become a supernova.
No, our sun is not destined to become a supernova and/or a black hole. It will become a red giant, but it is not massive enough to cross the threshold and become a candidate for a fate like either of those last two.
The onset of iron fusion causes a star to become a supernova. This process occurs when the star's core collapses due to the inability to support the fusion of iron, leading to a catastrophic explosion.
If the core of a supernova explosion contains three or more solar masses of matter, it will most likely become a black hole. The gravitational force is so strong that the core collapses into a singularity, forming a black hole.
A supernova happens when most of the core of the collapsing star has become neutrons, held up against gravity by neutron degeneracy pressure. At this point a shockwave reflects from the neutron star surface, driving the supernova explosion.So the answer to your question is neutrons.
No. It's a white dwarf, meaning that it has no more fuel left for such things.
The supernova would be so much brighter that it's hard to compare, at least 10 magnitudes brighter then Sirius. It would probably be about the same brightness as the full moon in the sky.
Only a very, very few stars have mass enough to become supernova. Jupiter is a planet not a star. It is far to small to become a star, let alone a supernova.
No. there is only 1 ghost.
i dont know
Oops! Not all stars end up as a supernova. To become a Type 2 supernova, the star has to be between 8 and 50 times larger than the Sun.
Sirius's fate might be peaceful; just ejecting it's outer red giant layers to make a planetary nebula. It is 2.02 times the mass of the Sun. However, Sirius has a white dwarf companion. On Sirius B's death, Sirius A might have formed. At the other end, Sirius B might destroy Sirius A. White dwarfs have very strong gravity, and if it is close enough, Sirius B might steal material from Sirius A. When a white dwarf stealing mass from the parent star has enough mass to create iron, the iron triggers a Type 1a supernova. If this happens to Sirius B, Sirius A could either be destroyed by the immense force of the explosion, or become a runaway star, travelling faster than even Barnard's Star. If this is the case, Sirius A might eat smaller stars or crash and burn into a larger star. If it heads towards us if this happens, we would be doomed.
Sirius B is already a white dwarf. The next transformation will be to become a black dwarf, but not for many many years.
No. It does not have enough mass to become a supernova.

he dies in the order if the phoenix, bellatrix kills him
If it's a big enough explosion it will become a supernova
