What is 2 ways a star can die?

A star can die in several ways, but two common methods are through supernova explosions and the formation of white dwarfs. For massive stars, once they exhaust their nuclear fuel, they may collapse under their own gravity, leading to a supernova explosion, which can leave behind a neutron star or black hole. In contrast, medium-sized stars like our Sun will shed their outer layers, forming a planetary nebula, while the core remains as a white dwarf that will gradually cool over time.
