Detailed explanation-1: -A star like our Sun will become a white dwarf when it has exhausted its nuclear fuel. Near the end of its nuclear burning stage, such a star expels most of its outer material (creating a planetary nebula) until only the hot (T > 100, 000 K) core remains, which then settles down to become a young white dwarf.
Detailed explanation-2: -Stars having initial mass less than or equal to 8 times the mass of the Sun ultimately become white dwarfs . Stars having initial mass between 8 to 25 times the mass of Sun become neutron stars through a supernova.
Detailed explanation-3: -Once all the helium disappears, the forces of gravity will take over, and the sun will shrink into a white dwarf. All the outer material will dissipate, leaving behind a planetary nebula.
Detailed explanation-4: -Once a star like the Sun has exhausted its nuclear fuel, its core collapses into a dense white dwarf and the outer layers are expelled as a planetary nebula.
