When the outward force due to fusion and radiation balances with the inward force of gravity, a star is said to be in a state of hydrostatic equilibrium. This balance between the forces maintains the star's stability and prevents it from collapsing or expanding uncontrollably.
hydrostatic equilibrium.
"While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star."
The equilibrium between the outward pressures of radiation and the force of gravity in a star helps to maintain its stable size and temperature. This balance prevents the star from collapsing under its own gravity or expanding uncontrollably due to radiation pressure.

In the radiation zone of a star, energy is transferred through electromagnetic radiation in the form of photons. These photons travel outward from the core of the star through the radiation zone, carrying thermal energy with them. This process allows the star to maintain its equilibrium by balancing the inward gravitational force with the outward pressure generated by this energy transfer.

The force that stops the sun from exploding is its own gravity, which creates pressure that balances the outward force of nuclear fusion occurring in the core. This delicate balance between gravity and pressure keeps the sun stable and prevents it from exploding.
Radiation
Yes, a stable star is in equilibrium, called hydrostatic equilibrium, when the outward pressure from heat caused by core fusion processes balances the inward pull of gravity. There are other factors which alter the form of stars such as their rotation or gravity from external sources such as a nearby mass.
The inward force of gravity is counteracted by two outward forces: gas pressure, and radiation pressure. Once the star runs out of fuel, the radiation pressure stops, the gas pressure is no longer enough to counteract gravity, and the star collapses - into a white dwarf, a neutron star, or a black hole, depending on its mass.
Gravity is what keeps objects in orbit around a planet from flying off into space. The gravitational pull between the planet and the objects creates a centripetal force that balances the outward motion, keeping them in a stable orbit.
Radiation. Mostly sunshine in, infrared radiation outward.
Our Sun is the star that continues to use hydrogen for energy through nuclear fusion in its core. The heat generated from this fusion process creates outward pressure that balances the inward pull of gravity, allowing the Sun to remain stable and shine brightly.
