dc.description.abstractWe 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 5±1 % and 6±1 % at 5 500 and 9 000 MHz, and we find a spectral index of −0.62±0.02 , typical of a young SNR. The average rotation measure is estimated at −124±83 rad m‾² and the magnetic field strength at ∼11 μG. We also estimate an equipartition magnetic field of 72±5 μG and minimum explosion energy of E min = 2.6 ×10⁴⁸ 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.
