Eddington limit (Sir A. Eddington)
The theoretical limit on which the photon pressure would go above the gravitational attraction of light-emitting body. i.e., a body emitting radiation at greater than the Eddington restrictions would break up through its own photon pressure.
By what percentage should the pressure of a given mass of gas be increased,so as to decrease its volume by 10% at a constant temperature.
