Supersonic waves of magnetization in dark interstellar molecular clouds

Abstract

We suggest that supersonic linewidths inferred from recent measurements of magnetic fields toward the core position in dark interstellar molecular clouds may be due to transverse waves of magnetization propagating in a poorly ionized, magnetically ordered gas-dust medium composed of tiny ferromagnetic dusty grains suspended in a cold gaseous cloud of molecular hydrogen. © 2000 MAIK "Nauka/Interperiodica".
