How is stellar equilibrium finally reached?

Answer 1

When gravity makes the core of a star so hot and dense that nuclear fusion commences, that pressure balances gravity and establishes equilibrium.

This is the process by which stars form: the potential energy released during the collapse of the interstellar gas, which is primarily hydrogen-1, is converted to heat and the gas gets denser. When the gas reaches a certain mass (roughly 80 times that of Jupiter), it reaches millions of degrees and a high density, which allows the hydrogen-1 to fuse to helium. The pressure created by this fusion is what keeps the universe in balance with gravity.

Answer 2

Finally, a star reaches stellar equilibrium when the pressure from nuclear fusion reactions pushing outward from the star's core balances the forces of gravity pulling inward.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
