Explanation:
Detailed explanation-1: -The star turns on and becomes a main sequence star, powered by hydrogen fusion. Fusion produces an outward pressure that balances with the inward pressure caused by gravity, stabilizing the star.
Detailed explanation-2: -Once the last of the hydrogen is used up in the core of an aging main sequence star, fusion stops in the core and the temperature drops and the core collapses. The collapsing core converts gravitational energy (potential energy) into thermal energy (kinetic energy).
