Scientific paper

We propose AXAF observations to spatially resolve the emission from X-ray faint early-type galaxies. Their X-ray emission mechanism is not well understood. Unlike the X-ray bright ellipticals in which most of the emission is from hot interstellar gas with T~1 keV, X-ray faint galaxies have hard (~5keV) and very soft (~0.2keV) spectral components. The hard component is assumed to be from low mass X-ray binaries (LMXBs), but the origin of the very soft component is mysterious. We suggested that LMXBs also produce the very soft emission, as it is seen in nearby LMXBs in our Galaxy and in the bulge of M31. These observations should resolve the soft and hard emission into individual sources, and will determine the spectral properties of the LMXBs and/or diffuse thermal gas in these galaxies.
