The supersoft X-ray sources are a distinct class of X-ray sources identified by ROSAT. They are characterized by very high luminosities (Lbol ~ 1038 ergs s−1) and black body temperatures of kT~ 30–60 eV. These sources are easily detected in the LMC and SMC because of the low column density of absorbing H gas. Thus, the samples found there are complete. They are much more difficult to find in the Galaxy due to soft X-ray absorption in the galactic plane.
