The final stage for our star, the Sun, is a White Dwarf. Here's why:
1. Explanation: As the Sun exhausts its nuclear fuel and enters the final stages of its life cycle, it will expand into a red giant and eventually shed its outer layers, leaving behind a dense core composed mostly of carbon and oxygen.
2. Formation of a White Dwarf: This dense core, known as a White Dwarf, will be the remnant of the Sun after it has gone through the red giant phase. White Dwarfs are incredibly dense and hot objects that no longer undergo nuclear fusion but instead slowly cool over billions of years.
3. Characteristics of a White Dwarf: White Dwarfs are roughly the size of Earth but contain a significant portion of the Sun's mass. They are stable objects supported by electron degeneracy pressure, which prevents further gravitational collapse.
4. Comparison with Other Options: Neutron Stars, Proton Stars, and Black Holes are not the final stages for stars like the Sun. Neutron Stars form from the remnants of massive stars, Proton Stars are not a recognized astronomical object, and Black Holes are formed from the gravitational collapse of massive stars.
In conclusion, the final stage for our star, the Sun, is a White Dwarf, marking the end of its evolutionary journey as a stable, cooling stellar remnant.
