Extreme Ultraviolet Emission from Neutron Stars
We summarize the detections of extreme ultraviolet (EUV) emission from neutron stars. Three rm detections have been made of spin-powered pulsars: the aged millisecond pulsar PSR J0437?4715, the middle-aged X-ray pulsar Geminga, and the radio pulsar PSR B0656+14. These observations allow us to evaluate both power-law and thermal-law emission models as the source of the EUV ux. For the case of PS...

متن کاملSources of radiation from neutron stars
I give a brief introduction to the problem of detecting gravitational radiation from neutron stars. After a review of the mechanisms by which such stars may produce radiation, I consider the different search strategies appropriate to the different kinds of sources: isolated known pulsars, neutron stars in binaries, and unseen neutron stars. The problem of an all-sky survey for unseen stars is t...
متن کاملUnidentified Egret Sources
The Compton Gamma-Ray Observatory was launched in early 1991 and deorbited in June, 2000. Between April 1991 and September 1995, the Energetic Gamma Ray Experiment Telescope (EGRET) detected 416 gamma-ray excesses with a significance of more than 3 σ above the diffuse background emission. After a careful analysis with a maximum-likelihood procedure, only 271 of these sources were included in th...
متن کاملWhich unidentified EGRET sources are gamma-ray pulsars?
We consider high energy γ-ray radiation from the radio pulsars associated with some unidentified EGRET γ-ray sources. Calculated efficiencies for the conversion of spin-down power to γ-rays and the energy spectra of the high energy γ-rays from these possible γ-ray pulsars in outer gap models are compared with observed results. Of these possible γ-ray pulsars, our results indicate that (i) PSR B...
