It has the mass of the sun, but squeezed into a space the width of a city. Using deep Chandra observations of the globular cluster M28, we study the quiescent X-ray emission of a neutron star in a low-mass X-ray binary in order to constrain the chemical composition of the neutron star atmosphere and the equation of state of dense matter. We fit the spectrum with different neutron star atmosphere models composed of hydrogen, helium or carbon. Nuclei and neutron stars 208Pb, ˘10 kg15m, 10 25 neutron star, ˘10 Km, 1030 kg (2 M solar) Stefano Gandol (LANL) - stefano@lanl.gov Neutron stars 3/30 A neutron star is the imploded core of a massive star produced by a supernova explosion. It is assumed they have densities of 3.7 × 10 17 to 6 × 10 17 kg/m 3, which is comparable to the approximate density of an atomic nucleus of 2.3 × 10 17 kg/m 3. The canonical view of neutron stars has their magnetic field lines looking like those surrounding a bar magnet, with north and south sides emerging from circular spots at opposing ends of the star. The Neutron star Interior Composition Explorer (NICER) mission will study neutron stars, the densest known objects in the cosmos. The diagram below shows a slice of a neutron star. Neutron stars cram roughly 1.3 to 2.5 solar masses into a city-sized sphere perhaps 20 kilometers (12 miles) across. The golden age of neutron-star physics has arrived These stellar remnants are some of the Universe’s most enigmatic objects — and they are finally starting to give up their secrets. The composition of their cores is unknown, but they may consist of a neutron superfluid or some unknown state of matter. They are so dense that one teaspoon of its material would have a mass over 5.5×10 12 kg. Using deep Chandra observations of the globular cluster M28, we study the quiescent X-ray emission of a neutron star in a low-mass X-ray binary in order to constrain the chemical composition of the neutron star atmosphere and the equation of state of dense matter.
Matter is packed so tightly that a sugar-cube-sized amount of material would weigh more than 1 billion tons, about the same as Mount Everest! These neutron star animations and graphics highlight some of their unique characteristics. This past June, SpaceX’s 11th resupply mission to the International Space Station brought with it a 372-kilogram box containing an X-ray telescope called the Neutron Star Interior Composition Explorer (NICER). Introduction to neutron stars. Poorly understood properties of the strong force do indeed affect our understanding of matter at those extraordinary densities (see e.g., “Rethinking Neutron Stars“). Using deep Chandra observations of the globular cluster M28, we study the quiescent X-ray emission of a neutron star in a low-mass X-ray binary in order to constrain the chemical composition of the neutron star atmosphere and the equation of state of dense matter. Neutron stars have a radius on the order of 10 kilometres (6.2 mi) and a mass of about 1.4 solar masses. A neutron star is the collapsed core of a giant star, which before collapse had a total mass of between 10 and 29 solar masses.Neutron stars are the smallest and densest stars, excluding black holes and hypothetical white holes, quark stars, and strange stars.
