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 square root of the ratio is about 6. I dislike the formula here as it makes Jeans Mass for Bernard 68, 10.117 solar masses and Cambridge's formula makes Jeans Mass 1.662 solar masses assuming it is all molecular hydrogen not just mostly. Anyway, it is advertised in Wikipedia as a collapsing cloud a star that will be born in 200,000 years.
Comparison of Rayleigh–Jeans law with Wien approximation and Planck's law, for a body of 5800 K temperature.. In physics, the Rayleigh–Jeans law is an approximation to the spectral radiance of electromagnetic radiation as a function of wavelength from a black body at a given temperature through classical arguments.
