Can Nonlinear Hydromagnetic Waves Support a Self-gravitating Cloud?

Using self-consistent magnetohydrodynamic (MHD) simulations, we explore the hypothesis that nonlinear MHD waves dominate the internal dynamics of galactic molecular clouds. We employ an isothermal equation of state and allow for self-gravity. We adopt "slab-symmetry," which permits motions v_ and fields B_ perpendicular to the mean field, but permits gradients only parallel to the mean field. The Alfvén speed v_A exceeds the sound speed c_s by a factor 3-30. We simulate the free decay of a
