Massive Stars.
Massive Stars.
many stars die as a supernova. not really able to determine which types, because they die at random, but if they dont die as supernovas, they just collapse and disappear into one point in the sky.
its called a super nova.
Yes Star spend most of their life span as a main sequence star. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole.
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.
Very large ones.

The most massive ones. The exact amount of mass requires varies, depending on the type of supernova, and on the element mix of the initial star.

Unlike the other types of supernovae, Type Ia supernovae generally occur in all types ofgalaxies, including ellipticals and they show no preference for regions of current stellar formation - they can occur anywhere in the Milky Way Galaxy.The reason for this is that Type 1 supernovae occur when the remnant of a small star (a white dwarf) accreets enough mass (by gas capture from, or merger with another star) to exceed the Chandrasekhar limit of about 1.38 solar masses. When this mass is exceeded carbon fusion is reignited in the stellar core and the star explodes and as white dwarf stars are to be found everywhere in Galaxies and Globular clusters, the potential for Type 1 supernovae is universal. That said, obviously you would not expect to find White Dwarf stars in current star forming areas (because the dwarf forms at the end of a stars main sequence life). However Galactic rotation mixes old stars with new stars relatively quickly and this separation rapidly blurs.
Stars are expected to end up as white dwarves, neutron stars, or black holes. If you are interested in the stages before that (when the star still produces power), that include red giants, and supernovae.
Supernovae are when very massive stars finally come to the end of their life. They are important events as during the very short period in which the explosion occurs, temperatures and pressures are sufficient to fuse atoms, making heavier elements. Any elements with a nucleus heavier than the iron nucleus would have had to be formed during a supernova explosion.
No, but some stars end their life by becoming a black hole.
The massive stars turn into gas
The most massive stars will end up as black holes. Those are the stars that have more than approximately 3 solar masses at the end of their life - i.e., AFTER the supernova explosion.
They are called white dwarfs.
