The Southern Crab from a new perspective

New Hubble Space Telescope images and Cerro Tololo Inter-American Observato ry echelle spectra of the nebula around the symbiotic Mira Henize 2-104 are presented. The nebula consists of two nested hourglass-shaped structures a nd a collimated polar jet. Spatiokinematical modeling shows that all three outflows were ejected during approximately the same epoch, namely, about 57 00 years ago, with the adopted distance of 4.4 kpc, in a mass-loss event un related to the present outburst. We present a tentative model in which the outer pair of lobes and jets are produced by a high-velocity outflow from t he white dwarf companion to the Mira, while the inner, slowly expanding lob es are produced by the Mira wind itself.
