Dynamics of Charged Particles Around a Magnetized Black Hole with pseudo–newtonian potential

Communications in Theoretical Physics 2013年第10期60卷 433-438页

作者：王颖伍歆孙威 Department of Physics Nanchang University School of Astronomy and Space Science Nanjing University College of Geography Science Nanjing Normal University

The linear stability of equilibria of charged particles moving near a compact object with a dipole magnetic field and a pseudo-newtonian potential is analyzed detalledly. An optimal fourth-order force gradient symplectic method, as a global symplectic integrator that can simultaneously solve both the equations of motion and the variational equations, is used to calculate fast Lyapunov indicators. In this way, dynamical structures are described, and parameter domains for causing chaos are found.

Dynamics of particles around a pseudo-newtonian Kerr black hole with halos

作者：王颖伍歆 Department of Physics Nanchang University

The regular and chaotic dynamics of test particles in a superposed field between a pseudo-newtonian Kerr black hole and quadrupolar halos is *** particular,the dependence of dynamics on the quadrupolar parameter of the halos and the spin angular momentum of the rotating black hole is *** is found that the small quadrupolar moment,in contrast with the spin angular momentum,does not have a great effect on the stability and radii of the innermost stable circular orbits of these test *** addition,chaos mainly occurs for small absolute values of the rotating parameters,and does not exist for the maximum counter-rotating case under some certain initial conditions and *** means that the rotating parameters of the black hole weaken the chaotic *** is also found that the counter-rotating system is more unstable than the co-rotating ***,chaos is absent for small absolute values of the quadrupoles,and the onset of chaos is easier for the prolate halos than for the oblate ones.

Gravitational Waves from a pseudo-newtonian Kerr Field with Halos

引用

Communications in Theoretical Physics 2011年第12期56卷 1045-1051页

作者：王颖伍歆 Institute of Astronomy & Department of Physics Nanchang University

A close relation between gravitational waveforms and the types of trajectories in a superposed field between a pseudo-newtonian Kerr black hole and quadrupolar halos is shown in detail The gravitational waveforms emitted from circular, KAM tori and chaotic orbits must be periodic, quasiperiodic and stochastic, respectively. The chaotic motion can maximally enhance both the amplitudes and the energy emission rates of the waves.
