What forms from a supernova?

Depending on the mass of the original star it will either end up as a neutron star (< 20 solar masses) or a black hole (> 20 solar masses).


If the core of a supernova explosion contains three or more solar masses of matter the core will most likely become a what?

If sufficient mass remains after the supernova explosion, it will become a black hole.


How many solar masses does a star have to have before a supernova is produced?

four


What mass is required for a Type ll supernova?

Stars with a mass about 9 solar masses, or greater, will explode as a type II supernova.


When a star experiences a supernova it must have what?

A lot of mass. Generally for a type II supernova more that 9 solar masses. See related question.


A supernova reaction occurs in the life cycle of which type of star?

A massive star. Usually any star with more that 9 solar masses will explode as a supernova.


Is a supernova a super giant?

A supernova may have been a supergiant star at one time, but it did not have to be. Any star with a mass greater than 3 times our sun will supernova. There are millions of stars having masses between 3 solar masses and supergiant mass for every single supergiant star... and every one will supernova when it dies.


What happen to a large star?

Supernova. Stars below nine solar masses become white dwarfs, though stars more than 1.4 solar masses (Chandrasekhar limit) should nova during their life time. http://en.wikipedia.org/wiki/Supernova http://en.wikipedia.org/wiki/Chandrasekhar_limit


A star the size of two stellar masses forms as a result of a supernova explosion what is the star called?

Following certain types of Supernova events there can often be a gravitational collapse of massive stars and this can result in the stellar remnant becoming a neutron star. Based on the Tolman-Oppenheimer-Volkoff limit the solar mass of a neutron star can range from 1.5 to 3.0 solar masses.


Do stars die?

Yes, eventually they all burn out. Stars with less than three solar masses will become a neutron star. These are extremely, extremely dense forms. Any larger and the star will become a black hole after going supernova.


What determines what stage comes after a supernova?

The amount of mass in the remnant. If the mass of the remnant exceeds 3 solar masses then it will become a black hole.


What type of star explodes in a type II supernova?

Supergiant stars of at least eight solar masses will explode as Type II supernovas.
