Jeans instability
The Jeans instability is a concept in astrophysics that describes an instability that leads to the gravitational collapse of a cloud of gas or dust. It causes the collapse of interstellar gas clouds and subsequent star formation. It occurs when the internal gas pressure is not strong enough to prevent the gravitational collapse of a region filled with matter. It is named after James Jeans. For stability, the cloud must be in hydrostatic equilibrium, which in case of a spherical cloud translates to d p d r = − G ρ ( r ) M enc ( r ) r...
