When and what is disturbed by outside explosion it may form an accretion disk?

An accretion disk is typically formed when a massive object, such as a black hole or a neutron star, experiences an outside explosion, like a supernova or a stellar collision. This explosion can disturb the surrounding material, causing it to spiral inward and accumulate around the massive object. As the material falls in, it heats up due to gravitational forces and friction, resulting in the formation of an accretion disk. These disks are often observed in various astrophysical contexts, including binary star systems and active galactic nuclei.
