Spinning Particles Around a Charged Black Hole

1. Charged Black Hole Basics: A charged black hole, also known as a Reissner-Nordström black hole, is a solution to Einstein's field equations that represents a non-rotating, spherically symmetric black hole with electric charge. The spacetime around a charged black hole is more complex than around a non-charged (Schwarzschild) black hole due to the additional electromagnetic fields. 2. Orbits of Particles: Geodesics: Particles around a charged black hole follow paths called geodesics. The charge of the black hole affects these paths due to the combined influence of gravity and electromagnetism. Innermost Stable Circular Orbit (ISCO): The ISCO is the smallest stable orbit a particle can have around a black hole before it risks falling in. For a charged black hole, the ISCO is influenced by both the mass and charge of the black hole, as well as the charge and spin of the particle. 3. Spinning Particles: Spin-Orbit Coupling: A spinning particle (like an electron) around a charged black hole experiences spin-orbit coupling, where the particle’s spin interacts with the gravitational and electromagnetic fields. Mathisson-Papapetrou Equations: These equations describe the motion of spinning particles in curved spacetime, including the effects of both the particle’s spin and the black hole’s charge. 4. Effects of Charge: Electromagnetic Force: If the particle itself is charged, the electromagnetic force between the black hole and the particle must be considered. This force can either attract or repel the particle, depending on the signs of the charges. Charge-Induced Precession: The presence of charge can induce precession of the particle's orbit, leading to complex orbital dynamics. 5. Astrophysical Implications: Accretion Disks: In astrophysical scenarios, charged particles (like ions) in an accretion disk around a charged black hole may exhibit unique dynamics compared to neutral particles, potentially affecting the emission of radiation. Black Hole Evaporation: The charge of a black hole can influence its Hawking radiation and, consequently, its evaporation process.
