Precession resonances in hierarchical triple systems
نویسندگان
چکیده
We describe a new kind of resonance occuring in relativistic three-body hierarchical systems: the precession resonance, when timescale binary equals period distant perturber. find that, contrary to what most previous studies assume, it can lead an exponential increase eccentricity even dominates quadrupolar perturbation. The may happen observation band LISA or change distribution triples. discuss physics showing that mainly depends on three parameters.

Nutational resonances, transitional precession, and precession-averaged evolution in binary black-hole systems
In the post-Newtonian (PN) regime, the time scale on which the spins of binary black holes precess is much shorter than the radiation-reaction time scale on which the black holes inspiral to smaller separations. On the precession time scale, the angle between the total and orbital angular momenta oscillates with nutation period τ, during which the orbital angular momentum precesses about the to...
متن کاملSecular Evolution of Hierarchical Triple Star Systems
We derive octupole-level secular perturbation equations for hierarchical triple systems, using classical Hamiltonian perturbation techniques. Our equations describe the secular evolution of the orbital eccentricities and inclinations over timescales long compared to the orbital periods. By extending previous work done to leading (quadrupole) order to octupole level (i.e., including terms of ord...
متن کاملMagnetically Driven Warping, Precession and Resonances in Accretion Disks
The inner region of the accretion disk onto a rotating magnetized central star (neutron star, white dwarf or T Tauri star) is subjected to magnetic torques which induce warping and precession of the disk. The origin of these torques lies in the interaction between the surface current on the disk and the horizontal magnetic field (parallel to the disk) produced by the inclined magnetic dipole: T...
متن کاملImproved equations for eccentricity generation in hierarchical triple systems
In a series of papers, we developed a technique for estimating the inner eccentricity in hierarchical triple systems, with the inner orbit being initially circular. However, for certain combinations of the masses and the orbital elements, the secular part of the solution failed. In the present paper, we derive a new solution for the secular part of the inner eccentricity, which corrects the pre...
متن کاملHierarchical Triple-Modular Redundancy (H-TMR) Network For Digital Systems
Hierarchical application of Triple-Modular Redundancy (TMR) increases fault tolerance of digital Integrated Circuit (IC). In this paper, a simple probabilistic model was proposed for analysis of fault masking performance of hierarchical TMR networks. Performance improvements obtained by second order TMR network were theoretically compared with first order TMR network.
