The initial explosion is over in seconds
Either somebody shoots at the star. Or kills the star turning it into a supernova.
A type-I supernova occurs when a white dwarf star accumulates mass from a companion star until it reaches a critical threshold, triggering a runaway nuclear fusion reaction. This causes the white dwarf to explode in a bright supernova event.
They will end up as neutron stars or even black holes. Usually they will first explode as a supernova (of type1a).
Massive stars, typically with a mass greater than 8 times that of our Sun, explode in a type II supernova. These stars undergo a core collapse followed by a massive explosion, resulting in the release of vast amounts of energy and debris into space.
No. There are two ways of generating a supernova: a star at least 8 times the mass of the sun collapsing and exploding or a white dwarf interacting or colliding with a companion star. Our sun is not massive enough to explode when it dies and does not have a companion star.
Supernova.

Some stars explode in a supernova.
Some stars do. They can be nova or supernova stars, depending on the scale of the explosion.
A supernova comes to existence when a white dwarf drains the matter from any companion star up to a point in wich it cannot carry anymore, and then it will first implode, and afterwards it will explode, a supernova.
we would explode and if there were survivors they would freeze to death
Antares is a red supergiant and has enough mass to explode as a supernova and then collapse into a black hole.
Yes it does. With as much power as 10 trillion of the most powerful hydrogen bombs known to man.
They explode as a supernova/hypernova to form a planetary nebula/black hole.
A type-I supernova occurs when a white dwarf star accumulates mass from a companion star until it reaches a critical threshold, triggering a runaway nuclear fusion reaction. This causes the white dwarf to explode in a bright supernova event.
Percentage wise. Most stars do not explode. Only about 1 in 3 million will explode as a supernova. The rest, like our Sun will just die quietly and become white dwarfs.
A supergiant star can explode into a supernova, where the outer layers are ejected into space. What remains may collapse into a neutron star or black hole, depending on the mass of the original star.
