Abstract

We present a new radio continuum study of the Large Magellanic Cloud supernova remnant (SNR) MC SNR J0519-6902. With a diameter of 8 pc, this SNR shows a radio ring-like morphology with three bright regions towards the north, east, and south. Its linear polarisation is prominent with average values of % and % at 5500 and 9000 MHz, and we find a spectral index of, typical of a young SNR. The average rotation measure is estimated at rad m and the magnetic field strength at G. We also estimate an equipartition magnetic field of G and minimum explosion energy of E = 2.6 erg. Finally, we identified an H i cloud that may be associated with MC SNR J0519-6902, located in the southeastern part of the remnant, along with a potential wind-bubble cavity.
