What is the life cycle of a massive star?

Question

Owen Atkinson · Accepted Answer

The life cycle of a massive star starts with the normal star and ends with either a neutron star or black hole

Big star, red supergiant, supernova, and either a neutron star or a black hole are the end products.

Nova Adams · Answer

undefined The stages of a massive star's life cycle are as follows: 1. **Nebula**: Initially, a massive star is a cloud of gas and dust called a nebula. 2. **Protostar**: Due to gravity, the nebula contracts and forms a protostar. 3. **Main Sequence**: Fusion reactions begin in the core, and the star enters the main sequence phase where it fuses hydrogen into helium. 4. **Red Supergiant**: As hydrogen depletes, the star expands and turns into a red supergiant. 5. **Supernova**: When the core collapses, it can cause a supernova explosion, leaving behind a neutron star or a black hole. 6. **Neutron Star or Black Hole**: The remnants of the core either form a neutron star or a black hole, depending on how massive the star is.
