Abstract

We present what is, as far as we know, the first direct determination of the grain velocity structure in a circumstellar expanding envelope around an AGB star. This was obtained at the CFH 3.6 m telescope through high resolution long slit spectroscopy in the far red (8200 Å) on the central 8 arcsec core of the Frosty Leo bipolar nebula associated with HH 34 IRS5. If this condensation is part of a spherical shell dynamically related to two kinds of stellar wind might have been present: and isotropic wind that has created the shell and a highly collimated wind that is at the origin of the jet.
