Vela pulsar (PSR 0833-45, Vela X)
subject			fact

Vela pulsar	is a part of Vela
	has synonym PSR 0833-45
	has synonym Vela X
	has definition A compact radio source about 400-500 pc distant associated with the Vela supernova remnant (q.v.). It has a nonthermal radio spectrum and is about 20 percent polarized. It is associated with the Gum Nebula, the Vela pulsar, and the X-ray source 2U 0832-45, although the pulsar and the X-ray source are displaced about 0°.7 from the center of the Vela X radio emission. Vela Y and Vela Z are outlying components, also nonthermal, but too weak to exhibit polarization.
	has definition A pulsar about 400-500 pc distant, probably associated with the Vela supernova remnant. Period 0.0892 seconds.
