Jeans radius

Webuid of density ˆcontained within a rotating cylinder of radius R. The cylinder and the uid rotate at angular speed about the axis of the cylinder. It is readily shown from Equations (15) and (16) that the uid can be in true equilibrium, with no pressure gradient (i.e. the gravitational and centrifugal forces balance), if 2 = 2ˇGˆ. WebThe Jeans radius is given by r J = 5 3 R 3 2 r 0 − 1 2, where R is the cloud radius. The latter can be interpreted as the maximum radius α, given in Eq. (3.152), i.e., R = (3/κ 0)r …

WebOnce the Jeans wave number is known, we can immediately obtain the Jeans radius and mass, which give the critical length and mass scales above which condensate dark matter collapses. In the approximation when rotation and quantum force are ignored, the Jeans radius and mass coincide with the radius and mass of the static condensate. WebThe earliest stage of stellar evolution is the formation of protostars, pre-nuclear burning objects. However, our concept of how globules and cores in molecular clouds collapse to form protostars is far from complete. Sir James Jeans defined the ‘Jeans Criterion’ in the early 20th Century for the conditions required for collapse to occur.
