![]() ![]() In 1967, Jocelyn Bell and Antony Hewish discovered regular radio pulses from CP 1919. ![]() It collapses so much that proton and electron combine to form neutrons. The central region of the star collapses under gravity. This explosion blows off the outer layers of a star into a beautiful super- nova remnant. After these stars have finished burning their nuclear fuel, they undergo a supernova explosion. They result from massive stars which have mass greater than 6-8 times that of our Sun. Neutron stars are one of the possible end states for a massive star. Neutron stars can also carry magnetic fields a million times stronger than the strongest magnetic fields produced on Earth. īecause of its small size and high density, a neutron star possesses a surface gravitational field about 2 × 10 11 times that of Earth. This means that a neutron star is so dense that on Earth, one teaspoonful would weigh a billion tons. Neutron stars are about 20 km in diameter and have a mass of about 1.4 times that of our Sun. In seeking an explanation for the origin of a supernova, they proposed that the neutron star is formed in a supernova explosion. In 1934 Walter Baade and Fritz Zwicky proposed the existence of neutron stars, only a year after the discovery of the neutron by Sir James Chadwick. Octupole, Neutron star, Magnetic flux, Radiation pressure Introduction So, this is the neutron star’s unique property, with evidence supported by two rotating axis than other stars with one rotating axis. This result leads to violate the known electromagnetic radiation in the far zone is not vanish rapidly. The radiation pressure generated from octupole field lines of neutron star is calculated and the pressure dominates at the surface and rapidly drops it in the far zone. The radiation from such a source is calculated and is shown to be diffuse. The octupole magnetic field of a neutron star is maximum at the surface and ceases to zero in the far distant zone, but visible as pair lobes looks like dipole.įinally, the octupole field strength is dominated at the surface than the dipole field, this leads to Neutron stars octupole field near the center is more significant. The magnetic field of a neutron star is derived from flux conservation and is high during the age of its birth. 2D case-section of the field lines of a neutron star is drawn. I have derived the field lines corresponding to a magnetic octupole moment. The sun rotates once every 107 seconds this implies that a typical neutron star with radius 10 km rotates 108 times faster than the size of our sun with radius 105 km. The rotation period of a neutron star is calculated using angular momentum conservation and the result led that, the rotation period of neutron star is τηs ∼ 0.1 s. This kind of neutron star is called a pulsar and it is supposed radiator. This shows a neutron star is strongly magnetized at birth. The dying star collapses to form a neutron star, magnetic flux conservation results in the formation of regions of extremely strong magnetic field near the neutron star. In this paper I have found the magnetic field strength of a neutron star, by using flux conservation, which the size of the sun as a progenitor star and its magnitude is Bη=9 × 1014 G which is approximately quadruple of magnetic field of the sun. ![]()
