Radio detection of nebulae around four LBV stars in the LMC
  The nebulae associated to four Luminous Blue Variables (LBVs) in the Large
Magellanic Cloud (LMC) have been observed at 5.5 and 9 GHz using the Australia
Telescope Compact Array, and radio emission has been detected for first time in
these sources, R127, R143, S61 and S119. The radio maps of the nebulae have an
angular resolution of \sim 1.5" and a sensitivity of 1.5-3.0\times10-2 mJy
beam-1, and show a very similar morphology to that observed in H{\alpha}. This
similarity permit us to assume that the H{\alpha} emission is not affected by
strong intrinsic extinction due to dust within the nebulae. We estimate the
masses of the ionized gas in the LBVs nebulae and their values are consistent
with those measured in Galactic LBVs.
