Ruling out chaos in compact binary systems.
We investigate the orbits of compact binary systems during the final inspiral stage before coalescence by integrating the post-Newtonian equations of motion. We include spin-orbit and spin-spin coupling, which, according to a recent study [J. Levin, Phys. Rev. Lett. 84, 3515 (2000)], may cause the orbits to appear chaotic. To examine this claim, we calculate the divergence of nearby trajectorie...
متن کاملComment on "ruling out chaos in compact binary systems".
Intuitively, black hole binaries are obvious candidates for chaotic dynamics. Firstly, they are highly non-linear systems and chaos is an expression of extreme nonlinearity. Secondly, there are isolated unstable orbits around a Schwarzschild black hole, and unstable orbits are a red flag for the onset of chaos. Surely the orbits only become more unstable and more complex when there are two blac...
متن کاملRuling out and ruling in neural codes.
The subject of neural coding has generated much debate. A key issue is whether the nervous system uses coarse or fine coding. Each has different strengths and weaknesses and, therefore, different implications for how the brain computes. For example, the strength of coarse coding is that it is robust to fluctuations in spike arrival times; downstream neurons do not have to keep track of the deta...
متن کاملRuling Out Bacillus anthracis
Optimization of methods for ruling out Bacillus anthracis leads to increased yields, faster turnaround times, and a lighter workload. We used 72 environmental non-B. anthracis bacilli to validate methods for ruling out B. anthracis. Most effective were the use of horse blood agar, motility testing after isolates had a 2-h incubation in trypticase soy broth, and screening isolates with a B. anth...
متن کاملMagnetic Interaction in Ultra-compact Binary Systems
This article reviews the current works on ultra-compact double-degenerate binaries in the presence of magnetic interaction, in particular, unipolar induction. The orbital dynamics and evolution of compact white-dwarf pairs are discussed in detail. Models and predictions of electron cyclotron masers from unipolar-inductor compact binaries and unipolar-inductor white-dwarf planetary systems are p...
