WebNotice that the expression for the Jean's length λ = k B T r 3 G M μ depends on both the size of the region in containing the mass and temperature of the cloud. It should be obvious that the if a region of the cloud is contracting then r gets smaller while M remains the same. WebTo Jeans, physics suggests that planets and life are exceedingly rare.

WebSolution Rayleigh-jeans law: A black body in thermal equilibrium will emit radiation in all frequency ranges, and as the frequency increases, so does the energy of the radiation emission. The black body is a matter that can absorb and emit all … WebThe Rayleigh-Jeans Law was an important step in our understanding of the equilibrium radiation from a hot object, even though it turned out not to be an accurate description of nature. The careful work in developing the Rayleigh-Jeans law laid the foundation for the quantum understanding expressed in the Planck radiation formula. In outline ...

Kinetic treatment of the Jeans gravitational instability, with collisions taken into account, is presented. The initial-value problem for the distribution function which obeys the kinetic equation, with the collision integral conserving the number of particles, is solved.
