Hydromagnetic Waves in Weakly Ionised Media. I. Basic Theory, and Application to Interstellar Molecular Clouds

Telemachos Ch. Mouschovias, Glenn E. Ciolek, S. A. Morton

We present a comprehensive study of MHD waves and instabilities in a weakly ionised system, e.g., an interstellar molecular cloud. We determine all the critical wavelengths of pert…
