This measure arises from the gravitational instability which occurs if the collapse time for an overdense cloud of interstellar gas is shorter than the time for sound waves to cross it.
This measure arises from the gravitational instability which occurs if the collapse time for an overdense cloud of interstellar gas is shorter than the time for sound waves to cross it. If the gravitational force tending to draw material towards the center of a cloud is greater than the opposing force due to gas pressure, then the cloud will contract. Identify this measure of the mass that a cloud of interstellar gas must have before it can contract under its own weight to form a protostar, that is, FTP, named for the British scientist who also amended a 1900 law that describes the spectral distribution of black-body radiation and which was first published by Lord Rayleigh.
