hannahj · Answer

Pressure and gravity. Pressure due to fusion reactions pushes outwards. Gravity pulls inwards to keep the star in equilibrium.

swordtotheheart · Answer

Gravity is one of the answers, as it pulls gasses to the star to keep it in equilibrum. Pressure is also one of the answers, as the nuclear fusion reactions push the gass forward.
