List Of Neutron Stars
Neutron stars are the collapsed cores of supergiant stars. They are created as a result of supernovas and gravitational collapse, and are the second-smallest and densest class of stellar objects. In the cores of these stars, protons and electrons combine to form neutrons. Neutron stars can be classified as pulsars if they are magnetized, if they rotate, and if they emit beams of electromagnetic radiation out of their magnetic poles. They may include soft gamma repeaters (SGR) and radio-quiet neutron stars, as well as pulsars such as radio pulsars, recycled pulsars, low mass X-ray pulsars, and accretion-powered pulsars. A notable grouping of neutron stars includes the Magnificent Seven.

Parsec
The parsec (symbol: pc) is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to or (AU), i.e. . The parsec unit is obtained by the use of parallax and trigonometry, and is defined as the distance at which 1 AU subtended angle, subtends an angle of one arcsecond ( of a degree (angle), degree). The nearest star, Proxima Centauri, is about from the Sun: from that distance, the gap between the Earth and the Sun spans slightly less than one arcsecond. Most Naked-eye stars, stars visible to the naked eye are within a few hundred parsecs of the Sun, with the most distant at a few thousand parsecs, and the Andromeda Galaxy at over 700,000 parsecs. The word ''parsec'' is a shortened form of ''a distance corresponding to a parallax of one second'', coined by the British astronomer Herbert Hall Turner in 1913. The unit was introduced to simplify the calculation of astronomical distances from raw observational data. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RX J0822−4300
, - style="vertical-align: top;" , Galactic coordinates , 260.3841 −03.4718 RX J0822−4300, often referred to as a "Cosmic Cannonball", is a radio-quiet neutron star currently moving away from the center of the Puppis A supernova remnant at , making it one of the fastest moving stars ever found. Earlier, it was believed to move with speed as high as 1,500 km/s. Astronomers used NASA's Chandra X-ray Observatory to observe the star over a period of 11 years to determine its speed. Although the cosmic cannonball is not the only hypervelocity star discovered, it is unique in the apparent origin of its speed. Others may have derived theirs from a gravitational slingshot around the Milky Way's suspected supermassive black hole, Sagittarius A*. Current theories fail to explain how such speeds can be attained from a supernova explosion. It could be a possible quark star.

SGR 1806−20
SGR 1806−20 is a magnetar, a type of neutron star with a very powerful magnetic field, that was discovered in 1979 and identified as a soft gamma repeater. SGR 1806−20 is located about 13 kiloparsecs (42,000 light-years) from Earth on the far side of the Milky Way in the constellation of Sagittarius. It has a diameter of no more than and rotates on its axis every 7.5 seconds ( rotation speed at the equator on the surface). , SGR 1806-20 is the most highly magnetized object ever observed, with a magnetic field of over 1015 gauss (G) (1011 tesla) intensity (compared to the Sun's 1–5 G and Earth's 0.25–0.65 G). Explosion Forty-two thousand years after a starquake occurred on the surface of SGR 1806-20, the radiation from the resultant explosion reached Earth on December 27, 2004 ( GRB 041227). In terms of gamma rays, the burst had an absolute magnitude of around −29. It was the brightest event known to have been sighted on this planet from an origin outside t ...
