Now, MIT astronomers have observed a wider swath of winds, in Hercules X-1, a system in which a neutron star is drawing material away from a sun-like star. This neutron star’s accretion disk is unique in that it wobbles, or “precesses,” as it rotates.
Web2 de may. de 2014 · It is generally believed that the outer, low-density part of a neutron star (crust) consists of a body-center-cubic lattice of neutron-rich nuclei, embedded in a gas of electrons and, if any, dripped neutrons, and near normal nuclear density ( ρ 0) , the nuclei melt into uniform nucleonic matter, which mainly composes the star's core [ 1 ]. WebThe mass of an electron is very small compared to a proton or a neutron. Since the nucleus contains protons and neutrons, most of the mass of an atom is concentrated in its nucleus.
Webproton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron. Protons, together with electrically neutral particles called neutrons, make up all atomic nuclei except for the hydrogen nucleus (which consists of a single proton). Every …
