DOI: 10.1029/2020gl090749

Abstract: Energetic electron dynamics is highly affected by plasma waves through quasilinear and/or nonlinear interactions in the Earth's inner magnetosphere. In this letter, we provide physical explanations for a previously reported intriguing event from the Van… read more here.

DOI: 10.1093/mnras/staf313

Abstract: In this paper, we model the plasma environment of Ganymede by means of a collisionless test particle simulation. By coupling the outputs from a DSMC simulation of Ganymede’s exosphere (i.e. number density profiles of neutral… read more here.

DOI: 10.1103/physrevd.107.084011

Abstract: The dynamics of a binary system moving in the background of a black hole is affected by tidal forces. In this work, for the Kerr black hole, we derive the electric and magnetic tidal moments… read more here.

DOI: 10.1103/physrevd.95.104052

Abstract: We study the motion of massive particles with electric and magnetic charges in the background of a magnetically charged Garfinkle-Horowitz-Strominger stringy black hole. We solve analytically the equations of motion of the test particles and… read more here.

DOI: 10.1142/s0217751x21500731

Abstract: In this study, a new equation of motion of a spinning charged test particle is examined. This equation is a counterpart of Papapetrou equations in Riemannian geometry when the charge of the particle disappears. By… read more here.
