Heating the warm ionized medium

ABSTRACT:If photoelectric heating by grains within the diffuse ionized component of the interstellar medium is 10 exp -25
ergs/s per H atom, the average value within diffuse H I regions, then grain
heating equals or exceeds photoionization heating of the ionized gas.
This
supplemental heat source would obviate the need for energetic ionizing photons to
balance the observed forbidden-line cooling and could be responsible in part
for enhanced intensities of some of the forbidden lines.
