On heating by ion streams in H II/OH regions
Abstract
Hartquist (1979) has argued recently that ion streams which could invert H II/OH masers would also heat up the regions to unacceptably high temperatures. I show that when cooling processes are analyzed more carefully, the temperature in the maser region remains sufficiently low in spite of the heating by ion friction.
