These observations permit us to resolve the innermost envelope of this star revealing the existence of a complex structure that involves extended continuum emission and molecular emission showing a non-radial gas velocity distribution. This molecular emission displays prominent red-shifted absorptions located right in front to the star typical of material infall and lateral gas motions compatible with the presence of a torus-like ","authors_text":"(2) Observatorio Astron\\'omico Nacional, (3) Dept. of Space, Astronomy, Chalmers University of Technology, CSIC, Earth, Environment, G.
