Radial oscillations in neutron stars from QCD
نویسندگان
چکیده
We study the stability against infinitesimal radial oscillations of neutron stars generated by a set equations state obtained from first-principle calculations in cold and dense QCD constrained observational data. consider mild large violations conformal bound, $c_{s} = 1/\sqrt{3}$, that can possibly contain quark matter core. Some star families mass-radius diagram become dynamically unstable due to oscillation amplitudes near

متن کاملRadial Oscillations of Neutron Stars in Strong Magnetic Fields
The eigen frequencies of radial pulsations of neutron stars are calculated in a strong magnetic field. At low densities we use the magnetic BPS equation of state(EOS) similar to that obtained by Lai and Shapiro while at high densities the EOS obtained from the relativistic nuclear mean field theory is taken and extended to include strong magnetic field. It is found that magnetised neutron stars...
متن کاملNon-linear radial oscillations of neutron stars: Mode-coupling results
The non-linear behaviour of oscillation modes in compact stars is a topic of considerable current interest. Accurate numerical studies of such phenomena are likely to require powerful new approaches to both fluid and spacetime computations. We propose that a key ingredient of such methods will be the non-linear evolution of deviations from the background stationary equilibrium star. We investig...
متن کاملDiscrimination of Quark Stars from Neutron Stars in Quadrupole Oscillations
The frequencies and damping times due to gravitational radiation are calculated for selfbound quark star models. The results are compared with those for neutron star models. They are markedly contrasted in less relativistic cases. The distinction derived here from a simple model of quark stars may be relevant to the future theoretical and observational studies, since the oscillation properties ...
متن کاملRadial Oscillations of Hybrid Stars
We study the effect of quark and nuclear matter mixed phase on the radial oscillation modes of neutron stars. For this study we have considered recent models from two classes of equations of state namely the relativistic mean field theoretical models and models based on realistic nucleon-nucleon interactions incorporating relativistic corrections and three body nuclear interactions.
