  1. NEUTRON STARS By Emma Jenkyn

  2. What is a Neutron star? A neutron star is a type of remnantthat can result from the collapse of a massive starduring a Type II, Type Ib or Type Ic supernova. Neutron stars are very hot and are supported against further collapse because of the Pauli exclusion principle This principle means that two neutrons can’t occupy the same place and quantum state at the same time.

  3. How are Neutron stars made? Neutron stars are made as the core of a massive star is compressed during a supernova, and collapses. It then retains most of its angular momentum ,since it has only a tiny fraction of its parent's radius. A neutron star is formed with very high rotation speed, and then gradually slowed down.

  4. How big is a Neutron Star? The gravity on the Neutrons Star's surface is about 2 × 1011 times stronger than on Earth. The escape velocity is about 100,000 kms. A Neutron Star is so dense that the mass is 900 times the great pyramid of Giza! The temperature of a Neutron Star is around 1011to 1012kelvins (0 kelvins= 273.15 degrees).

  5. What is a Neutron Star made of? A Neutron star is made of ordinary atomic nuclei crushed into solid lattice with a sea of electrons flowing through gaps between it. It is believed that nuclei may be made of iron. The atmosphere of a Neutron Star is at lease 1 metre thick and its dynamic is fully controlled by the stars magnetic fields.

  6. History of Neutron Stars A neutron particle was discovered in 1932 by Sir James (In 1935 Sir James was awarded the Nobel Prize in Physics for this discovery). In 1934, Walter Baade and Fritz Zwicky announced the existence of the neutron star, only a year after Chadwick's discovery of the neutron particle. They discovered the way Neutron stars are made when researching origins of supernovas. The first sighting of a neutron star from a telescope on earth

  7. Rotation Neutron stars rotate extremely rapidly after their creation due to the conservation of angular momentum. The slow rotation of the original star's core speeds up as it shrinks. A newly made neutron star can rotate several times a second. Sometimes the neutron star absorbs orbiting junk from another close star, increasing the rotation to several hundred times per second reshaping the neutron star into an spheroid.

  8. Amount At present there are about 2000 known neutron stars in the Milky Way and the Magellanic Clouds, the majority of which have been detected as radio pulsars. The population of neutron stars is mainly along the edge of the Milky Way. The reason for this spread is that neutron stars are born with high speeds (400 km/s) as a result of an momentum-kick from an asymmetry during the supernova explosion process. One of the closest known neutron stars is PSR J0108-1431 at a distance of about or 424 light years away.

  9. PicturesIllustrations. This believed to be a explosion of a neutron star in 1054 The explosion on the surface of a neutron star 50,000 light years away. Resulting in a flash of energy ,which lasted only a tenth of a second and it released more energy than the Sun emits in 150,000 years. Believed to be the closest neutron star to Earth.
