D ec 1 99 7 Innermost Stable Circular Orbit of a Spinning Particle in Kerr Spacetime
We study stability of a circular orbit of a spinning test particle in a Kerr spacetime. We find that some of the circular orbits become unstable in the direction perpendicular to the equatorial plane, although the orbits are still stable in the radial direction. Then for the large spin case (S ∼ O(1)), the innermost stable circular orbit (ISCO) appears before the minimum of the effective potent...
متن کاملLetter 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...
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 کاملBehaviour of Charged Spinning Massless Particles
We review some properties of a relativistic classical massless charged particle with 9 spin interacting with an external electromagnetic field. We give in particular a proper definition 10 of kinetic energy and total energy, the latter being conserved when the external field is stationary. 11 We find that the particle’s velocity may differ from c as a result of the spin electromagnetic field 12...
