The dynamics of the motion of a two component superfluid system in the core of a neutron star yields an equation for the evolution of the pulsar's rotation period. The spin down of the star owing to energy release at the core boundary, which is associated with a contraction of the length...
The identification of pulsars as rotating neutron stars has led to an increased interest in the structure calculation of neutron stars. It may be said with reasonable confidence that the state of matter in the outer regions of a neutron star is relativel
Within a microscopic approach the structure of Neutron Stars is usually studied by modelling the homogeneous nuclear matter of the core by a suitable Equation of State, based on a many-body theory, and the crust by a functional based on a more phenomenol
The neutron in-core instrumentation is composed of vanadium detectors arranged in lances. These lances are located vertically in the moderator at three different radiuses relative to the core axis. The three most inner lances are provided for supervising the conical upper central core region which ...
Maximum Quark Core in a Neutron Star for Realistic Equations of State For recently developed realistic equations of state (Wiringa, Fiks, & Fabrocini 1988), we establish conditions which the quark matter equation of state sho... M Kutschera,A Kotlorz - 《Astrophysical Journal》 被引量: 7发表...
This inner core will ultimately radiate away its thermal energy, cool, and go on to form a neutron star or a black hole. Revival of the stalled shock above the neutrinosphere is mediated by the absorption of electron neutrinos and antineutrinos emerging from the radiating proto-neutron star. ...
star. There could be several to tens of them in the Milky Way, says Philipp Podsiadlowski, a stellar astrophysicist at the University of Oxford, UK. The presence of a neutron star — the corpse of a normal star left behind after a supernova — would disrupt the usual thermonuclear fires...
It is commonly believed that the magnetic field threading a neutron star provides the ultimate mechanism (on top of fluid viscosity) for enforcing long-term corotation between the slowly spun down solid crust and the liquid core. We show that this argument fails for axisymmetric magnetic fields ...
neutron star with energy release similar to a supernova explosion: initially, a low-mass star with a quark core is formed; the subsequent accretion leads to configurations with a radius of 1000 km; and, finally, the second catastrophic restructuring gives rise to a star with a radius of 100...
Furthermore, we set strict upper limits on the X-ray luminosity of any undetected point sources, and we exclude the presence of a neutron star associated with W49B. We conclude that the morphological, spectral, and environmental characteristics of W49B are indicative of a bipolar Type Ib/Ic SN...
