The temperature of the hot X-ray gas contained within early-type galaxies is an important diagnostic of the hydrodynamical processes that affect the gas. Previous studies of X-ray bright ellipticals indicate that they are all hotter than the kinetic motion of the stars, and it has been suggested that the gas is in the potential well of a massive dark matter halo that is dynamically hotter than the stars. X-ray faint galaxies have lost most of their gas, possibly because of a shallower dark matter potential well. If this is true, then the gas that does remain in these galaxies should have a temperature that more closely reflects the stellar kinetic temperature. We propose to observe three X-ray faint galaxies to determine their temperature and test this prediction.
