cloud fragmentation

(clumping in clouds due to gravitational instability)

Cloud fragmentation is the clumping of a cloud (e.g., molecular cloud) due to gravitational instability, i.e., regions of the cloud where the forces are balanced such that a volume of high density increases its own density, decreasing the density of the volume around it. The concept is assumed in current theories of star formation and in some models of planet formation (gravitational instability models).
