A star is in equilibrium when 6 (9u ,n.n(ezwbp/zknp t 4sxmzulj 82it radivlqx *) bhymah*7qiu3zqk /6qe55oq.:1i mpd ates at its surface all the energy generated at its core. What happens when it begins to geu .o5 b1h *qahe)6iyqxp m/ 3vq5zdi7qm:ql* knerate more energy than it radiates? Less energy? Explain.
参考答案:
When a star generates more energy than it radiates, its temperature increases, which produces a greater outward pressure that overcomes the inward gravitational forces and the star increases in size. When a star generates less energy than it radiates, its temperature decreases, which produces a smaller outward pressure and the star decreases in size as the inward gravitational forces start to overcome the outward radiation pressure.
