Description
The innermost stable circular orbit
(ISCO) is a concept in general relativity that defines the closest possible circular orbit around a massive, compact object (like a black hole or a star) where a test particle can remain in a stable orbit.
Closer than the ISCO, no stable orbits exist; a particle closer than the ISCO will spiral down into the black hole.
This presentation will briefly introduce ISCO, and will discuss different ISCOs such as the ones for Schwarzschild and Rissner-Nordstrom black holes. Then ending with a quick view of my research on ISCO of global monopole RN-black holes in a constant magnetic field.
