When supernova explodes
because of the collapsing cores, the core itself will become a neutron star or
a white dwarf without undergoing any kind of explosive transformation. The white
dwarf stars can also become supernova if they orbit another star in a binary
system and steal material from their companion. In addition, the end state of a
star, whether it will explode as a supernova become a black hole.
Answer: For supernova explosions caused by collapsing cores, the core itself will either become a<u> </u><u>Black-hole </u>or a <u>Neutron Star</u>.
Explanation:
A massive star becomes a Red Super-giant towards the end of its journey. It goes supernova. The inner core becomes either a neutron star or a black-hole. The remnant becomes neutron star if the initial mass of the star is three to eight solar mass. Star having initial mass more than eight solar mass forms a black-hole after supernova.
Hence, the correct options are:
For supernova explosions caused by collapsing cores, the core itself will either become a<u> </u><u>Black-hole </u>or a <u>Neutron Star</u>.
