Reflection and dissipation of Alfvén waves in interstellar clouds
Reflection and dissipation of Alfvén waves in interstellar clouds
Context: Supersonic nonthermal motions in molecular clouds are often interpreted as long-lived magnetohydrodynamic (MHD) waves. The propagation and amplitude of these waves is affected by local physical characteristics, most importantly the gas density and the ionization fraction. Aims: We study the propagation, reflection and dissipation of Alfv\'en waves in molecular …
