Bound near-equatorial orbits around neutron stars
Recent discovery of kilohertz quasi-periodic brightness oscillations of low mass X-ray binaries (LMXBs) has attracted attention to highly relativistic periodic motion near accreting neutron stars. Most models proposed so far involve (almost) inertial motion in the vicinity of the stars’ innermost stable circular orbits. In the present paper we study general-relativistic circular and eccentric o...
متن کاملRadiative Evolution of Orbits around a Kerr Black Hole
We propose a simple approach for the radiative evolution of generic orbits around a Kerr black hole. For a scalar-field, we recover the standard results for the evolution of the energy E and the azimuthal angular momentum Lz . In addition, our method provides a closed expression for the evolution of the Carter constant Q. Recently, the prospects of a direct observation of gravitational radiatio...
متن کاملAtom galleries for whispering atoms: binding atoms in stable orbits around an optical resonator.
The external fields of optical whispering gallery modes may be used to confine atoms in stable orbits around a dielectric microsphere. As an example, a toroidal dipole-force trap (atom gallery) for three-level atoms is investigated, and the possibility of achieving an atomic (matter-wave) resonator is discussed. The extremely small electromagnetic mode volumes and high Q's of the whispering gal...

متن کاملRadiation-reaction-induced evolution of circular orbits of particles around Kerr black holes.
It is demonstrated that, in the adiabatic approximation, nonequatorial circular orbits of particles in the Kerr metric ~i.e., orbits of constant Boyer-Lindquist radius! remain circular under the influence of gravitational radiation reaction. A brief discussion is given of conditions for breakdown of adiabaticity and of whether slightly noncircular orbits are stable against the growth of eccentr...
