Observations of supernova remnants in the Large Magellanic Cloud with the Einstein ObservatoryConsideration is given to the Large Magellanic Cloud (LMC), noting that above 2 keV, the X-ray luminosity of the LMC is dominated by emission from 3-5 point sources similar to the bright sources near the center of our own Galaxy. The imaging proportional counter aboard the Einstein Observatory has been used to locate about 40 X-ray sources in the LMC. Supernova remnants observed in the LMC are presented, noting X-ray position, X-ray counting rate, and radio flux. For the six brightest sources, X-ray spectra have been analyzed to determine temperatures and intrinsic luminosity corrected for the interstellar absorption. These data are compared for parameters for the young galactic remnant of Tycho's supernova. Attention is given to the ratio of X-ray luminosity to radio luminosity, and the data are discussed within the framework of the standard blast-wave theory. The results of applying the model to recorded observations are numerically presented. In addition to providing a sample of objects for investigations of supernova remnants, the data are applicable to studies of galaxies of other morphological types and individual objects, such as N49.
