Multiple Choice

What is the difference between a normal pulsar,which emits radiation in the radio range,and a pulsating X-ray source?

• A) A pulsating X-ray source combines the characteristics of an ordinary pulsar and a variable star. The surface pulsates in and out creating a pulsating source.
• B) A pulsating X-ray source is a binary system of two pulsars in very rapid rotation around one another. We see the interference pattern of the two pulsar beams as a pulsating X-ray jet.
• C) A pulsating X-ray source is an ordinary pulsar, but occasionally, when the neutron star experiences a glitch and the crust cracks, the hot interior is exposed and emits an intense beam of X-rays.
• D) A pulsating X-ray source is a pulsar with a binary companion. Matter pulled off the companion spirals along the intense magnetic field of the pulsar, and its interaction with the surface produces X-ray jets.
