In a protostar, hydrostatic equilibrium is maintained by the balance between gravitational forces and thermal pressure. Gravity pulls the material inward, causing the protostar to collapse, while thermal pressure, generated by nuclear fusion and the heat from the collapsing gas, pushes outward. When these two forces are in balance, the protostar can maintain a stable structure as it continues to evolve toward becoming a star.
Hydrostatic equilibrium occurs when compression due to gravity is balanced by a pressure gradient which creates a pressure gradient force in the opposite direction. The balance of these two forces is known as the hydrostatic balance.
The main reactions that maintain stellar equilibrium are nuclear fusion reactions in the core, which produce energy that balances the gravitational force trying to collapse the star. The pressure generated by these reactions pushes outward, counteracting the gravitational force pulling inward, resulting in a stable balance known as hydrostatic equilibrium.
The balance of forces that keeps a star from collapsing is called hydrostatic equilibrium. This equilibrium occurs when the outward pressure generated by nuclear fusion in the star's core balances the inward gravitational force trying to collapse the star. If these forces are not balanced, the star may either contract under gravity or expand until a new equilibrium is reached.
As a protostar contracts under gravity, its gravitational potential energy is converted into kinetic energy, increasing the speed and temperature of the particles. This increase in kinetic energy results in collisions that generate heat. The protostar continues to contract and heat up until internal pressures and temperatures are enough to initiate nuclear fusion and establish equilibrium between inward gravitational forces and outward radiation pressure.

Yes, Pluto has been determined to be in hydrostatic equilibrium. Planets must orbit the sun (the first criterion for a planet), and must also be in hydrostatic equilibrium (which Pluto is). Pluto fails the third "planetary entrance test" set by the IAU in that it has not cleared its orbit of debris. A link can be found below to check facts and learn more.
The balance of forces that keep a star from collapsing is called hydrostatic equilibrium. This equilibrium is maintained between the inward force of gravity and the outward force generated by gas pressure within the star.

Equilibrium.
The first condition of equilibrium can be applied on concurrent forces that are equal in magnitude, since these produce translational equilibrium. But if the forces are equal in magnitude but are non concurrent then even first condition of equilibrium is satisfied but torque is produced which does not maintain rotational equilibrium. Hence for complete equilibrium that is, both translational and rotational , both the conditions should be satisfied.

Equilibrium Condition.
As a protostar contracts under gravity, its gravitational potential energy is converted into kinetic energy, increasing the speed and temperature of the particles. This increase in kinetic energy results in collisions that generate heat. The protostar continues to contract and heat up until internal pressures and temperatures are enough to initiate nuclear fusion and establish equilibrium between inward gravitational forces and outward radiation pressure.
