Multi-line diagnostics of the axi-symmetric wind around the MS-type AGB star RS Cancri

We present data recently obtained with NOEMA/PolyFiX on the MS-type Asymptotic Giant Branch (AGB) star RS Cnc, allowing to characterize in detail structure of its wind. These results became possible by recent advances NOEMA observatory, which combine large spectral bandwidth high sensitivity together still increasing spatial resolution.
