mass | quantity | The measure of the inertia of an object, determined by observing the acceleration when a known force is applied. The gravitational force acting on an object is found to be proportional to its mass, as is the gravitational force that it exerts on other objects. | |
Eddington limit | mass | In essence, radiation pressure must not exceed gravity. It is the limit beyond which the radiation force on matter in the emitting region is greater than the gravitational forces that hold the star together. LE = 4πcGM/Ks, where Ks = Thomson and/or Compton scattering opacity. Eddington limit for a 1 Msun star, 1038 ergs s-1. |
