Abstract (from CDS):

We present a detailed study of Australia Telescope Compact Array observations (λ = 20, 13, 6 and 3 cm) of supernova remnant (SNR) J0509-6731 in the Large Magellanic Cloud. The remnant has a ring morphology with brightened regions towards the south-western limb. We also find a second brightened inner ring which is only seen in the radio continuum. The SNR is almost circular, with a diameter ranging from 7 to 8 pc, and a steep radio spectral index between 36 and 3 cm of α = -0.73±0.02, which is characteristic of younger SNRs. We also report detection of radially orientated polarization across the remnant at 6 cm, with a mean fractional polarization level of P ≅ (26±13) percent. We find the magnetic field ( ∼ 168 µG) and Σ-D (Σ = 1.1x10–19 W/m2/Hz/sr, D = 7.35 pc) to be consistent with other young remnants.
