A BIPOLAR OUTFLOW IN THE M-1-67 NEBULA AROUND THE WOLF-RAYET STAR WR-124

Ground based high resolution coronographic images of the inner M 1-67 nebula (similar or equal to 40'' x 60'') around the Wolf Rayet WR 124 have been obtained with the Johns Hopkins Adaptive Optic Coronograph a t the Swope 40'' telescope, Las Campanas, in the light of H alpha + [N II]. The inner M 1-67 nebula appears very clumpy and remarkably axisym metric. In addition, we present new high signal-to-noise long slit spe ctroscopic data, with full spatial coverage of the nebula (similar or equal to 90'' x 75''), which have been used the save derive its radial velocity map (from the [NII] 6583 Angstrom line profile). The radial velocity data reveal the presence of two different motions in the envi ronment of WR 124: a spherical hollow shell, 46'' in radius, expanding with a velocity of 46 km s(-1), and a newly discovered bipolar outflo w, with a velocity of 88 km s(-1). Their dynamical ages are estimated to be 2 x 10(4) yrs and 1.2 x 10(4) yrs respectively, and their overal l N enriched composition seem to indicate that they formed during the post-main sequence evolution of WR 124. This scenario is consistent wi th two subsequent outbursts, possibly occurred during a previous LBV p hase.
