Origin and Evolution of accretion disk

First Known Use: 1973 year

Language of Origin: English

Story behind the word: The term 'accretion disk' originated in the field of astrophysics to describe a rotating disk of matter that forms around a massive central object, such as a star or black hole, due to gravitational forces.

Evolution of the word: The concept of accretion disks has been further studied and refined in astrophysics, leading to a better understanding of how they function and their role in the formation of planetary systems and galaxies.
