Morpho-kinematical modelling in the molecular zoo beyond CO: the case of M 1-92

Abstract Ongoing improvements of sub-mm- and mm-range interferometers and single-dish radiotelescopes are progressively allowing the detailed study of planetary nebulae (PNe) in molecular species other than 12 CO and 13 CO. We are implementing a new set of tables for extending the capabilities of the morpho-kinematical modelling tool SHAPE+shapemol , so radiative transfer in molecular species beyond 12 CO and 13 CO, namely C 17 O, C 18 O, HCN, HNC, CS, SiO, HCO + , and N 2 H + , are enabled under the Large Velocity Gradient approximation with the ease of use of SHAPE . We present preliminary results on the simultaneous analysis of a plethora of IRAM-30m and HERSCHEL/HIFI spectra, and NOEMA maps of different species in the pre-PN nebula M 1-92, which show interesting features such as a previously undetected pair of polar, turbulent, high-temperature blobs, or a 17 O/ 18 O isotopic ratio of 1.7, which indicates the AGB should have turned C-rich, as opposed to the apparent nature of its O-rich nebula.
