Hi. At different stages of a star's life different forces oppose gravity (always the inward pulling force). Gas pressure during formation, the pressure from fusion during most of the star's life, the extreme pressure of a nova or supernova detonation, and finally the solid neutron ball of a neutron star, or extremely dense white dwarf. (This ignores black holes because we have no idea what is inside.) Hope this helps.

Pressure from fusion reactions creates the outward force. Gravity creates the inward force.

a million. that could be a stability between the burden of its very own gravity and the fusion reaction going on interior it. 2. start comes by using forming out of a 'cloud' of count. dying comes by using working out of gas to maintain the fusion reaction which counters its gravity. 3. Earth's orbit and axis spin. 4. The fusion reaction. 5. i'm uncertain, yet given the actuality that blue gentle has an more desirable frequency, i'd hazard a guess on the blue celebrity. yet i'm no longer probably particular.
