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 become unstable and begin to collapse when it lacked sufficient gaseous pressure support to balance the force of gravity.
The Mysterious Universe is a popular science book by the British astrophysicist Sir James Jeans, first published in 1930 by the Cambridge University Press. In the United States, it was published by Macmillan. The book is an expanded version of the Rede Lecture delivered at the University of Cambridge in 1930. [1]

The Jeans equations are a set of partial differential equations that describe the motion of a collection of stars in a gravitational field. The Jeans equations relate the second-order velocity moments to the density and potential of a stellar system for systems without collision.
