Multifrequency study of SNR J0533-7202, a new supernova remnant in the
  LMC
  We present a detailed study of Australia Telescope Compact Array (ATCA)
observations of a newly discovered Large Magellanic Cloud (LMC) supernova
remnant (SNR), SNR J0533-7202. This object follows a horseshoe morphology, with
a size 37 pc x 28 pc (1-pc uncertainty in each direction). It exhibits a radio
spectrum with the intrinsic synchrotron spectral index of alpha= -0.47+-0.06
between 73 and 6 cm. We report detections of regions showing moderately high
fractional polarisation at 6 cm, with a peak value of 36+-6% and a mean
fractional polarisation of 12+-7%. We also estimate an average rotation measure
across the remnant of -591 rad m^-2. The current lack of deep X-ray observation
precludes any conclusion about high-energy emission from the remnant. The
association with an old stellar population favours a thermonuclear supernova
origin of the remnant.
