Context: The Supernova Remnants (SNRs) known in the Large Magellanic Cloud
(LMC) show a variety of morphological structures in the different wavelength
bands. This variety is the product of the conditions in the surrounding medium
with which the remnant interacts and the inherent circumstances of the
supernova event itself.
Aims: This paper performs a multi-frequency study of the LMC SNR J0530-7007
by combining Australia Telescope Compact Array (ATCA), Molonglo Observatory
Synthesis Telescope (MOST), R\"ontgensatellit (ROSAT) and Magellanic Clouds
Emission Line Survey (MCELS) observations.
Methods: We analysed radio-continuum, X-ray and optical data and present a
multi-wavelength morphological study of LMC SNR J0530-7007. Results We find
that this object has a shell-type morphology with a size of 215"x180" (52 pc x
44 pc); a radio spectral index (alpha=-0.85+-0.13); with [Sii]/Halpha > 0.4 in
the optical; and the presence of non-thermal radio and X-ray emission.
Conclusions: We confirmed this object as a bona-fide shell-type SNR which is
probably a result of a Type Ia supernova.
