Radio images of four luminous blue variable stars.

DUNCAN R.A. and WHITE S.M.

Abstract (from CDS):

We have used the Australia Telescope Compact Array to image four southern luminous blue variable stars: AG Car, He3-519, HR Car and WRA 751, at wavelengths of 3 and 6cm, and resolutions of 1 and 2arcsec respectively. With the partial exception of HR Car, all radio images show an unresolved stellar core surrounded by a large ionized gaseous nebula, and agree well with published Hα and [Nii] optical images. The image of WRA 751 shows a stellar torus or disc. HR Car's radio image is unusual, and seems best explained by the presence of a hot binary companion.
