Chaotic motion of Charged Particles in a Black Hole Magnetosphere
The observational data from the core of some galaxies reveal that the inner part of a gas disk around a supermassive black hole emits non-thermal adiation and radio waves. This may be explained by synchrotron emission from ultrarelativistic electron in a strong magnetic field in the innermost orbits around a supermassive black hole. In a realistic model of black hole accretion system, we should consider interactions between plasma fluid and magnetic field. However, to make a comprehensive analyses, we give an external magnetic field and we investigate in detail the motion of charged particles confined in the external magnetic field around a rotating black hole. We discuss the chaotic motion of charged particles in a black hole magnetosphere and show the black hole's spin effects on that chaotic motion.
