Letter to the Editor Keplerian frequencies and innermost stable circular orbits of rapidly rotating strange stars
It has been suggested that the frequency in the corotating innermost stable circular orbit (ISCO) about a compact stellar remnant can be determined through X-ray observations of low-mass X-ray binaries, and that its value can be used to constrain the equation of state of ultradense matter. Upon constructing numerical models of rapidly rotating strange (quark) stars in general relativity, we fin...

It has been suggested that the frequency in the co-rotating innermost stable circular orbit (ISCO) about a compact stellar remnant can be determined through X-ray observations of low-mass X-ray binaries, and that its value can be used to constrain the equation of state of ultradense matter. Upon constructing numerical models of rapidly rotating strange (quark) stars in general rel-ativity, we f...
متن کاملInnermost Stable Circular Orbit of Coalescing Neutron Star - Black Hole Binary — Generalized Pseudo - Newtonian Potential Approach —
The innermost stable circular orbits (ISCO) of coalescing neutron starblack hole binary are studied taking into account both the tidal and relativistic effects. We adopt the generalized pseudo-Newtonian potential to mimic the general relativistic effects of gravitation. It is found that the separation of the neutron star and the black hole at the innermost stable circular orbit is greater than ...
متن کاملASTRONOMY AND ASTROPHYSICS Innermost stable circular orbits around strange stars and kHz QPOs in low-mass X-ray binaries
Exact calculations of innermost stable circular orbit (ISCO) around rotating strange stars are performed within the framework of general relativity. Equations of state (EOS) of strange quark matter based on the MIT Bag Model with massive strange quarks and lowest order QCD interactions, are used. The presence of a solid crust of normal matter on rotating, mass accreting strange stars in LMXBs i...
متن کاملInnermost stable circular orbit of inspiraling neutron-star binaries: Tidal effects, post-Newtonian effects, and the neutron-star equation of state.
We study how the neutron-star equation of state affects the onset of the dynamical instability in the equations of motion for inspiraling neutron-star binaries near coalescence. A combination of relativistic effects and Newtonian tidal effects cause the stars to begin their final, rapid, and dynamicallyunstable plunge to merger when the stars are still well separated and the orbital frequency i...
