Stellar physics
Stellar Structure
A star is a self-regulating sphere of plasma in which the inward pull of gravity is balanced at every depth by the outward push of pressure — hydrostatic equilibrium. Energy generated by fusion in the core is carried outward by radiation and by convection, and a handful of coupled equations capture the whole structure.
