Non-pulsing emission from X-ray pulsars

Astrophysics 2007-05-23 v1

Abstract

Results of GRANAT/ART-P observations of three X-ray pulsars in non-pulsing states are presented: 1) a statistically significant non-pulsing flux with a simple power-law spectrum was detected during the ``off''- state of Her X-1; 2) a significant (13 σ\sigma) non-pulsing flux with a strong iron emission line at energies ~ 6.7-6.9 keV was detected during the eclipse ingress of Cen X-3; 3) a weak non-pulsing flux was detected during the X-ray eclipse of Vela X-1, which probably resulted from scattering of the pulsar emission in the stellar wind of an optical star.
