On the Radius of Neutron Stars
Abstract
Consideration is given to recent calculations of general relativistic effects in the beaming, spectrum, and pulse properties of accreting neutron stars. Some possible models for X-ray pulsars and QPOs are analyzed, which indicate that current observational and theoretical requirements can be explained with a value of the radius smaller than about two Schwarzschild radii. Concurrent information and calculations on several X-ray burster sources are compatible with this conclusion.
