Therefore, the X-ray flux at the peak of the burst should correspond to Eddington luminosity, which can be calculated once the mass of the neutron star is known (1.5 solar masses is a commonly used assumption).
Røntgenfluxen vil i dette tilfælde ved toppen af udbruddet svare til Eddington luminositeten, der kan beregnes når massen af neutronstjernen er kendt (1.5 solmasser er en almindelig antagelse).
