This … WebJeans' length is the critical radius of a cloud (typically a cloud of interstellar molecular gas and dust) where thermal energy, which causes the cloud to expand, is counteracted by gravity, which causes the cloud to collapse. It is named after the British astronomer Sir James Jeans, who concerned himself with the stability of spherical nebulae ... WebThe interstellar gas clouds move along the field lines (because of the "frozen in" condition) and fall into the "wells" of the field. This causes further stretching of the magnetic field lines, making the "wells" deeper; thus large amounts of gas can fall into the "wells," creating large concentrations of gas, which then become gravitationally unstable ( Gorbatskii 1977 ). difference between alter and modify in sql
