X-ray Pulsar
Schematic of an X-ray pulsar showing the misalignment between the spin axis and the magnetic poles. This misalignment causes the X-ray emitting hot spot to rotate into and out of view giving rise to X-ray pulses.

 


anomalous X-ray pulsar (AXP)
A type of X-ray pulsar with a very long axial rotation period (for a pulsar), of 6 to 12 seconds, combined with a very powerful X-ray emission that cannot be explained by such a low spin rate.

X-Ray Pulsars
Pulsars that radiate in the X-ray region of the spectrum. Best verified examples are Her X-1 and Cen X-3.

X-ray pulsars emit x-rays at regular intervals, either because of magnetospheric emission in neutron stars, or through the accretion of matter from a companion.

X-ray pulsars in a binary system allow the orbital parameters to be determined through: ...

An X-ray pulsar probably about 5 kpc distant, a member of an occulting binary system with an orbital period of 1.7 days. The visible component has been identified as the blue variable HZ Herculis, whose spectrum varies from late A or early F to B.

When they are young (with ages less than about 10,000 years) magnetars may be observed as soft gamma repeaters (SGRs) or anomalous x-ray pulsars. magnetic (NASA SP-7, 1965) 1. Of or pertaining to a magnet.

Some of the most spectacular are bright X-ray sources and are known as X-ray binaries or X-ray pulsars. In these systems, gas is being drawn from the outer layers of a companion star by the neutron star's gravitational pull.

Using NASA's Rossi X-ray Timing Explorer (RXTE), astronomers have discovered the first fast X-ray pulsar to be eclipsed by its companion star.

are many interesting phenomena in a neutron star binary system. We will just mention one. If the companion of the neutron star is a giant, material will be transferred from the giant to the neutron star. X-rays will be emitted and a X-ray pulsar is ...
