S S = (5.67 × 10 –8 W·m –2 ·K –4 ) (5800 K) 4 = 63 × 10 6 W·m –2. The surface area of a sphere with a radius r is 4πr 2. If r S is the radius of the Sun, the total energy it emits is S S 4πr s2. As the radiation is emitted from this spherical ... WebIf a rarefaction of 20% correspond to an increase in luminosity of, say, 10%, then as the next 20% rarefaction in Hydrogen will happen faster, the next relative increase of 10% in luminosity will happen faster too.
