Spin and Isospin Asymmetry, Equation of State and Neutron Stars
In the present work, we have obtained the equation of state for neutron star matter considering the in uence of the ferromagnetic and antiferromagnetic spin state. We have also investigated the structure of neutron stars. According to our results, the spin asymmetry stiens the equation of state and leads to high mass for the neutron star.
متن کاملNuclear pasta structure in hot neutron stars
Structure of cold and hot dense matter at subnuclear densities is investigated by quantum molecular dynamics (QMD) simulations. Obtained phase diagrams show that the density of the phase boundaries between the different nuclear structures decreases with increasing temperature due to the thermal expansion of nuclear matter region. At subnuclear densities, nuclear matter exhibits the coexistence ...
متن کاملOscillation Waveforms and Amplitudes from Hot Spots on Neutron Stars
The discovery of high-amplitude brightness oscillations during type I X-ray bursts from six low-mass X-ray binaries has provided a powerful new tool to study the properties of matter at supranuclear densities, the e†ects of strong gravity, and the propagation of thermonuclear burning. There is substantial evidence that these brightness oscillations are produced by spin modulation of one or two ...
متن کاملCharacteristic Numerical Relativity Applied to Hydrodynamic Studies of Neutron Stars
We present tests and results of a new axisymmetric, fully general relativistic code capable of solving the coupled Einstein-matter system for a perfect fluid matter field. Our implementation is based on the Bondi metric, by which the spacetime is foliated with a family of outgoing light cones. We use high-resolution shockcapturing schemes to solve the fluid equations. The code can accurately ma...
متن کاملModeling Spectral Features from Isolated Neutron Stars
We study several effects that influence the strength of the proton cyclotron and atomic features in the thermal spectra of magnetic neutron stars. Magnetic field variations over the neutron star surface leads to broadening of features. Vacuum polarization can strongly suppress spectral lines when B >∼ 10 G. The surface spectrum is unaffected by vacuum polarization when B <∼ 7× 10 G; thus the pr...
