Keplerian frequency of uniformly rotating neutron stars and quark stars
Aims. We calculate Keplerian (mass shedding) configurations of rigidly rotating neutron stars and quark stars with crusts. We check the validity of empirical formula for Keplerian frequency, fK, proposed by Lattimer & Prakash, fK(M) = C (M/M⊙) (R/10 km) , where M is the (gravitational) mass of Keplerian configuration, R is the (circumferential) radius of the non-rotating configuration of the sa...
متن کاملRadial Oscillations of Rotating Strange Stars in Strong Magnetic Fields
In this paper we study radial oscillations of the rotating strange stars in strong magnetic fields in the Density Dependent Quark Mass (DDQM) model. We see that increase of frequency i.e. difference in frequency of rotating and non-rotating stars is more for higher magnetic fields. The change is small for low mass stars but it increases with the mass of the star. This change of frequency is sig...
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.

متن کاملAsymptotic expressions for the angular dependence of low-frequency pulsation modes in rotating stars
Through the solution of Laplace’s tidal equations, approximated to describe equatorially trapped wave propagation, analytical expressions are obtained for the angular dependence of pulsation modes in uniformly rotating stars. As the ratio between rotation and pulsation frequencies becomes large, these expressions approach the exact solutions of the governing low-frequency pulsation equations. F...
متن کاملRadial oscillations of relativistic stars
We present a new survey of the radial oscillation modes of neutron stars. This study complements and corrects earlier studies of radial oscillations. We present an extensive list of frequencies for the most common equations of state and some more recent ones. In order to check the accuracy, we use two different numerical schemes which yield the same results. The stimulation for this work comes ...
