Abstract

We present a new radio continuum study of the Large Magellanic Cloud supernova remnant (SNR) MCSNRJ0519-6902. With a diameter of ∼8 pc, this SNR shows a radio ring-like morphology with three bright regions toward the north, east, and south. Its linear polarisation is prominent with average values of 5 ± 1% and 6 ± 1% at 5500 and 9000 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 MCSNRJ0519-6902, located in the southeastern part of the remnant, along with a potential wind-bubble cavity.
