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 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 کاملLast Orbits of Binary Black Holes * the Isco (for Innermost Stable Circular Orbit). 2. Numerical Solution
Received (Day Month Year) Binary black hole systems in the pre-coalescence stage are numerically constructed by demanding that the associated spacetime admits a helical Killing vector. Comparison with third order post-Newtonian calculations indicates a rather good agreement until the innermost stable circular orbit. 1. Quasi-equilibrium configurations of binary black holes 1.1. Helical Killing ...
متن کاملMixing zones in magnetized differentially rotating stars
We study the secular instability of magnetized differentially rotating radiative zones taking account of viscosity and magnetic and thermal diffusivities. The considered instability generalizes the well-known Goldreich-Schubert-Fricke instability for the case of a sufficiently strong nagnetic field. In magnetized stars, instability can lead to a formation of non-spherical unstable zones where w...
