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 12CO and 13CO. 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 12CO and 13CO, namely C17O, C18O, HCN, HNC, CS, SiO, HCO+, and N2H+, 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 17O/18O 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.
