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 کاملThe R-mode Instability in Rotating Neutron Stars
In this review we summarize the current understanding of the gravitational-wave driven instability associated with the so-called r-modes in rotating neutron stars. We discuss the nature of the r-modes, the detailed mechanics of the instability and its potential astrophysical significance. In particular we discuss results regarding the spin-evolution of nascent neutron stars, the detectability o...

متن کاملOn the relevance of the r-mode instability for accreting neutron stars and white dwarfs
We present a case study for the relevance of the r-mode instability for accreting compact stars. Our estimates are based on rough approximations that facilitate back-of-the-envelope calculations. We discuss two different cases: 1) For recycled millisecond pulsars we find that the r-mode instability can limit the rotation provided that the stars are hotter than about 2 × 10 K. The limiting rotat...
