Data obtained with ROSAT have established the “supersoft” X-ray sources (SSS) as a separate class of objects. Their unique features include temperatures of ∼30 eV and luminosities of ∼1038 erg s−1. Hasinger (1994) has recently summarized the properties of the SSS presently known in the Galaxy and the Magellanic Clouds (cf., Kahabka & Trümper 1995). The six which are thought to be LMC members are listed in Table 1 and discussed individually, based primarily on optical data we have obtained at CTIO.
