A radio pulsar/x-ray binary link.
Radio pulsars with millisecond spin periods are thought to have been spun up by the transfer of matter and angular momentum from a low-mass companion star during an x-ray-emitting phase. The spin periods of the neutron stars in several such low-mass x-ray binary (LMXB) systems have been shown to be in the millisecond regime, but no radio pulsations have been detected. Here we report on detectio...
متن کاملBinary Pulsar Shock Emissions as Galactic Gamma-ray Sources
We address several issues regarding the interpretation of galactic -ray sources. We consider powerful pulsars in binaries producing X-ray and gamma-ray unpulsed emission from the shock interaction of relativistic pulsar winds with circumbinary material. Nebular mass out ows from companion stars of binary pulsars can provide the right calorimeters to transform a fraction of the electromagnetic a...
متن کاملBinary millisecond pulsar discovery via gamma-ray pulsations.
Millisecond pulsars, old neutron stars spun up by accreting matter from a companion star, can reach high rotation rates of hundreds of revolutions per second. Until now, all such "recycled" rotation-powered pulsars have been detected by their spin-modulated radio emission. In a computing-intensive blind search of gamma-ray data from the Fermi Large Area Telescope (with partial constraints from ...
متن کاملAngular Momentum Transfer in the Binary X - ray Pulsar GX
We describe three presentations relating to the X-ray pulsar GX 1+4 at a workshop on magnetic fields and accretion at the Astrophysical Theory Centre, Australian National University on 1998, November 12-13. Optical and X-ray spectroscopy indicate that GX 1+4 is seen through a cloud of gravitationaly bound matter. We discuss an unstable negative feedback mechanism (originally proposed by Kotani ...
متن کاملA Strong X-ray Burst from the Low-mass X-ray Binary Exo 0748 676
We have observed an unusually strong X-ray burst as a part of our regular eclipse timing observations of the lowmass binary system EXO 0748 676. The burst peak flux was 5:2 ; 10 8 ergs cm s , approximately 5 times the normal peak X-ray burst flux observed from this source by RXTE. Spectral fits to the data strongly suggest that photospheric radius expansion occurred during the burst. In this pa...
