ABSTRACT:A simple model for supernova remnant sources of MHD waves is used to calculate the energy spectrum of waves in the intercloud medium and the heating
rate resulting from their dissipation.
Models of thermal phases of
interstellar gas in ionization and thermal equilibrium are then constructed, and it
is demonstrated that wave dissipation can be an important heating
mechanism which can account for the observed high H I temperatures in low-density
(intercloud) neutral gas.
