In stellar physics, the Jeans instability causes the collapse of interstellar gas clouds and subsequent star formation, named after James Jeans. It occurs when the internal gas pressure is not strong enough to prevent gravitational collapse of a region filled with matter. For stability, the cloud must be in hydrostatic … See more The Jeans mass is named after the British physicist Sir James Jeans, who considered the process of gravitational collapse within a gaseous cloud. He was able to show that, under appropriate conditions, a cloud, or part of one, would … See more Jeans' length is the critical radius of a cloud (typically a cloud of interstellar molecular gas and dust) where thermal energy, which … See more Jeans instability can also give rise to fragmentation in certain conditions.

WebJeans length basically states that a molecular cloud of a particular size can become unstable and begin collapse. The Radius in the above equation is Jeans Length, the minimum radius of the cloud before self-gravitation occurs.
