Eddington limit

(ˈɛdɪŋtən)
n
(Astronomy) astronomy the theoretical upper limit of luminosity that a star of a given mass can reach; occurs when the outward force of the radiation just balances the inward gravitational force
[C20: named after A. S. Eddington (1882–1944), English astronomer and physicist]

which is the Eddington luminosity. Stars dominated by radiation pressure in their photosphere are fully determined by the photosphere, meaning that their luminosities will adjust to match the Eddington luminosity.
(82-84) In this analysis, one needs to introduce the Eddington ratio [lambda], the bolometric luminosity divided by the Eddington luminosity, given as [L.sub.Edd] = 1.25 x [10.sup.38](M/M0) erg [s.sup.-1] for a black hole mass of M.
