Question

Which will be the last stage of evolution of a massive star?

• A. Nebula
• B. Neutron star
• C. White dwarf
• D. Black hole

Answer 1

Answer: (B), (D)

The correct options are
B Neutron star
D Black hole

The last stage of a star depends upon its mass. The three possible end stages of stars are as follows:

1. Stars having initial mass less than or equal to 8 times the mass of the Sun ultimately become white dwarfs .
2. Stars having initial mass between 8 to 25 times the mass of Sun become neutron stars through a supernova.
3. Stars having initial mass larger than 25 times the mass of the Sun undergo a supernova, but turn into black holes.

Thus, a massive star transforms itself into either a neutron star or a black hole.
