Abstract
High spatial and spectral resolution observations of the ring nebula surrounding the LBV candidate He 3-519 are presented. The data were obtained at the AAT with the UCL echelle spectrograph and cover the Hα and [N II] emission lines for two slit positions. The nebular motions are clearly resolved and have a total velocity spread of -40 to +100 km s−1. The shell shows some deviations from spherical symmetry but overall is expanding at 61 km s−1 and has an ionized mass of ∼ 2 M⊙. The nebular parameters are found to be similar to those of the AG Car nebula, suggesting that it resulted from a bulk ejection of material ∼ 2 × 104 yr ago.
