Quick Reference

A limit for the maximum value of the brightness of a star of a given mass. This limit exists because the radiation pressure caused by the nuclear fusion reactions powering the star has to counter, but not exceed, the gravitational force that would cause gravitational collapse of the star. The existence of this limit was first pointed out by the British astrophysicist Sir Arthur Stanley Eddington (1882–1944).
