Astronomers discover strange neutron star.
<P Align=center> </ P> <P> Italian astronomers have discovered an exotic neutron star, although it was born only in 2000, but the operation mode has been millions of years of history like a neutron star. .</ P> <P> the Italian National Astrophysics Institute of astronomers using the European XMM Newton telescope Zheke observed neutron star called 1E161348-5055. .Scientists calculate that the neutron star's history of only 2000, is known to one of the youngest neutron star. .</ P> <P> is an ultra-high density neutron star, quality and the sun quite, but the diameter of only 10 to 25 kilometers. .Nascent neutron stars usually rotate very fast, up to hundreds per second weeks. .However, although the newly discovered neutron star is very young, but older operating mode like a neutron star, one revolution every 6.7 hours before. .Neutron star millions of years is usually required to put the speed down to this level first. .</ P> <P> scientists said that a possible explanation is that the neutron star in supernova remnant from the adsorption of a dozen pieces. .These fragments form a disk around the neutron star, neutron star rotates through the magnetic field to transfer the angular momentum of the disk. .This method can reduce the neutron star's speed, but only if the composition of the neutron star different from other neutron stars. .</ P> <P> Another possible explanation is that the existence of the neutron star companion. .Neutron absorbing material from the companion body, while the companion's orbital period of 6.7 hours. .</ P> <P> scientists said, in order to better explain this phenomenon, the neutron star is still the need for a more detailed observations. .</ P> </ p>.
