Description
We quantify the energy radiated through all the collisional lines in a
photoionized nebula in the presence of temperature fluctuations in the
form of hot spots caused by an unknown heating process. The excess
energy radiated in the lines as a result of the fluctuations is found to
scale linearly with their mean-square amplitude t2. We find that the
combined mechanical luminosity of stellar winds, champagne flows and
photoevaporation flows from proplyds is insufficient to account for the
temperature fluctuations of typical HII regions, but that stellar winds
may possibly explain the fluctuations in planetary nebulae.
