Neutron Star Accretion and Binary Pulsar Formation - NASA/ADS In the standard scenario for binary pulsar formation, the neturon star from the explosion of the primary supergiant moves through the envelope of the companion star. Electron-degeneracy pressure is overcome and the core collapses furth… When all nuclear fuel in the core has been exhausted, the core must be supported by degeneracy pressure alone.

They are highly compressed cores of giant stars that are formed after their death as … The dense stars can also drive bursts of high-intensity radiation.The powerful collision released enormous amounts of light and created gravitational waves that rippled through the universe. Neutron stars are the densest known objects after the black holes found in the universe. The protons in the core collide with very high-energy electrons and create neutrons. Neutron stars are believed to form in supernovae such as the one that formed the Crab Nebula (or check out this cool X-ray image of the nebula, from the Chandra X-ray Observatory). The nature of a neutron star differs based on whether the neutron star formed from the collapse of a white dwarf, the collapse of a ∼ 8 – 11M ⊙ star, or the collapse of a more massive star (∼ 11 – 20M⊙). If the mass of the core is between 1.4 and 3.0 solar masses the core will only become a neutron star.
If the second star is less massive than the sun, it pulls mass from its companion into a Roche lobe, a balloon-like cloud of material that orbits the neutron star. The research also provided the first solid evidence that neutron-star collisions are the source of much of the universe's gold, platinum and other heavy elements.If a neutron star is part of a binary system that survived the deadly blast from its supernova (or if it captured a passing companion), things can get even more interesting. When a star explodes as a supernova, most of its matter is blown away into space to form a nebula (such as the Crab Nebula). "We use these pulsars the same way we use the atomic clocks in a GPS navigation system," Gendreau said.©Future US, Inc. 11 West 42nd Street, 15th Floor,New York,NY 10036.Neutron stars are city-size stellar objects with a mass about 1.4 times that of the sun. But what happened to the two objects after their smashup remains a mystery. Let's take a look at what they are, how they form, and how they vary. "The numbers are there, but it's hard to wrap our brains around them. "Spin-powered pulsars" are driven by the stars rotation, as high-energy electrons interact with the pulsar's magnetic field above their poles. The ultra-dense remnants of the imploding core which are left behind are known as a neutron star, as its electrons and protons are crushed together in the huge gravity to form neutrons. As the star evolves away from the main sequence, subsequent nuclear burning produces an iron-rich core. The envelope is then expelled through the hydrodynamic coupling of the dynamical friction.
Born from the explosive death of another, larger stars, these tiny objects pack quite a punch.
