Spinning test particle motion around a rotating wormhole

چکیده
In this work, we investigated the motion of spinning test particles around a rotating wormhole, extending, in way, previous work Benavides-Gallego et al. [Phys. Rev. D 101, 124024 (2020)] to general case. Using Mathisson-Papapetrou-Dixon equations, study effective potential, circular orbits, and innermost stable orbit (ISCO) particles. We found that both particle wormhole spins affect location ISCO significantly. On other hand, similar nonrotating case, also two possible configurations potential: plus minus. Furthermore, minimum value potential is not at throat due its spin $a$, contrast nonspinning where symmetric, wormhole. case ISCO, it increases as $a$ increases, black holes presence decreases ISCO. Finally, since dynamical four-momentum kinematical four-velocity are always parallel, consider superluminal bound, finding allowed values dimensionless particle's $s$ change wormhole's increases.

Electromagnetic field around a slowly rotating wormhole
We have considered the possibility of a slowly rotating wormhole surrounded by a cloud of charged particles. Due to slow rotation of the wormhole, the charged particles are dragged thereby producing an electromagnetic field. We have determined the strength of this electromagnetic field and the corresponding flux of radiation.
متن کاملSpinning Particle, Rotating Black Hole and Twistor-string * Rotating Black Hole as Spinning Particle
Structure of the spinning particle based on the rotating black hole solution is considered. It has gyromagnetic ratio g = 2 and a nontriv-ial twistorial and stringy systems. The mass and spin appear from excitations of the Kerr circular string, while the Dirac equation describes excitations of an axial stringy system which is responsible for scattering. Complex Kerr geometry contains an open tw...
متن کاملGravitational waves from a spinning particle in circular orbits around a rotating black hole.
Using the Teukolsky and Sasaki-Nakamura formalisms for the perterbations around a Kerr black hole, we calculate the energy flux of gravitational waves induced by a spinning particle of mass μ and spin S moving in circular orbits near the equatorial plain of a rotating black hole of mass M( μ) and spin Ma. The calculations are performed by using the recently developed post-Newtonian expansion te...
متن کاملIntegrability of spinning particle motion in higher-dimensional rotating black hole spacetimes.
We study the motion of a classical spinning particle (with spin degrees of freedom described by a vector of Grassmann variables) in higher-dimensional general rotating black hole spacetimes with a cosmological constant. In all dimensions n we exhibit n bosonic functionally independent integrals of spinning particle motion, corresponding to explicit and hidden symmetries generated from the princ...
متن کامل4 Rotating Black Hole , Twistor - String and Spinning Particle
We discuss basic features of the model of spinning particle based on the Kerr solution. It contains a very nontrivial real stringy structure consisting of the Kerr circular string and an axial stringy system. We consider also the complex and twistorial structures of the Kerr geometry and show that there is a complex twistor-string built of the complex N=2 chiral string with a twistorial (x, θ) ...
