A mechanism for heating dense interstellar clouds

Abstract

The rate of rotation of an interstellar cloud tends to increase as it contracts. As differential rotation occurs within a cloud, magnetic field lines are bent and twisted. The deformation of the magnetic field lines produces hydromagnetic waves and leads to a damping of the rotation. A large fraction of the rotational energy is transformed into the energy of hydromagnetic waves which heat the cloud.
