Magneto-Rotational Instability

Magneto-Rotational Instability (MRI) is a phenomenon that occurs in rotating astrophysical objects, like accretion disks around black holes or young stars, under the influence of magnetic fields. When the rotation speed and magnetic forces reach a certain balance, the instability can lead to enhanced turbulence, causing the material in the disk to mix and transport angular momentum. This process allows gas and dust to spiral inward, contributing to the formation of stars and the growth of black holes. MRI is a key mechanism in understanding how matter behaves in extreme cosmic environments.
