"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 ).
