X-Ray Bursting Neutron Stars
Abstract
The maximum peak luminosity of the X-ray bursts from a burster is most likely interpreted as the Eddington luminosity of a helium-rich envelope surrounding a neutron star. If this interpretation is true, it is possible to obtain a relation between the mass and the radius of the neutron star in terms of the maximum effective temperature of bursts. On the other hand, the most naive understanding of the origin of the 4.1 keV absorption line often detected in X-ray burst spectra gives another relation of the neutron star mass with its radius. By solving two simultaneous equations, the author determines the values of the mass and the radius of the neutron star, respectively. However, the result is critical to every neutron star model currently considered. The persistent emissions from X-ray bursters are also discussed.
