It would depend on how close the propagator star was.
The closest and most probable supernova event will be Betelgeuse at 600 light years. However, for the gamma rays to have a serious affect, the star needs to be less that 100 light years away.
Probably not - in fact quite the reverse! The elements they throw out into space can interact with the interstellar material to initiate star formation. I suppose if a star went supernova and it was in a close binary system, the other star might be badly affected; but this would in itself probably not actually destroy the other star - though it certainly wouldn't be quite as it was before!
Also, the 'metals' (to astronomers, metals means 'everything other than Hydrogen and Helium') will go on to be mixed in with those newly-forming stars and possibly then on to make organic life like you and me. So, like many things in nature that seem destructive (volcanoes, for example) supernovae create more than they destroy.
A black hole can gradually evaporate. However, for a stellar black hole, the rate of evaporation is currently much, much slower than the rate of mass increase - even if the black hole only only receives the 3 kelvin background radiation. Also, even without that, the time it takes for a supernova to evaporate is much, much longer than the current age of the Universe. For a supermassive (i.e., galactic) black hole, this situation is even more extreme.
No a supernova causes a black hole through implosion, iron accumulation and quark collission
No. However, it may cause serious damage to any living beings in nearby solar systems - even up to a thousand light-years away or so - assuming there are such living beings.
No. Our Sun will never become a supernova and no other stars are near enough to damage us were they to do so.
Definitely. Any planets and their moons in that star's system are gone.
Yes. Strong centers of gravity can rip a star apart. The strongest known centers of gravity are black holes, but other much more massive stars can destroy smaller stars if they get too close to one another. Humans do not currently have any technologies that can destroy a star (even excusing the problem of getting the device to the star in question).
No, only large stars go supernova when nuclear fusion breaks down. While white dwarfs can go supernova in some instances, brown dwarfs are failed stars which are not powered by nuclear fusion.
Well in space there are billions of stars. Stars are like humans they are born, they live for a while and eventually die out. When a star reaches the end of its life it starts to produce elements in its core such as helium and other elements but when it produces IRON it has signed its death certificate, after just a few seconds after the star has produced iron it has a supernova. A supernova is the single most destructive force known to man. A supernova will destroy anything in its path. When the supernova is over all that is left is a white dwarf which is so dense that if you was to drop a sugar cube on its surface it would sink into its core thousands of miles deep. Hope I answered your question, if you have anymore questions reply back.
Massive stars. See related question: 2nd Answer: Yes, massive stars, but ones with another star like a red giant orbiting each other. The to-be supernova 'sucks' material from the other star near it until its mass is large enough to make the star collapse and burst.

Yes, from the remains of a supernova and from the outer layers of gas shed through a black dwarf.
no. the new stars are constantly formed in nebulae from dust from other stars that have either gone supernova or imploded on itself
No, only large stars go supernova when nuclear fusion breaks down. While white dwarfs can go supernova in some instances, brown dwarfs are failed stars which are not powered by nuclear fusion.
Heavy stars go supernova at the end of their lives.
Massive Stars.
They supernova.
Supernova
SuperNova
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.

Some stars do. They can be nova or supernova stars, depending on the scale of the explosion.
