PSR B 1257+12 | pulsar | hidden mass | A pulsar in the constellation Virgo and the site of the first solar system to be discovered outside our own. The planets were detected in 1991. | ||
Vela pulsar | pulsar | Vela X | A pulsar about 400-500 pc distant, probably associated with the Vela supernova remnant. Period 0.0892 seconds. | ||
X-ray pulsar | pulsar | hidden mass | Pulsar (q.v.) that radiates in the X-ray region of the spectrum. Best verified examples are Her X-1 and Cen X-3. They are thought to be rotating, strongly magnetic neutron stars of about 1 Msun in a grazing orbit around a more massive star from which they are accreting matter. |
