With the aim of unravelling the complexity of the morpho-kinematics of the circumstellar envelope (CSE) of Mira Ceti, we review, extend and possibly revisit ALMA millimetre observations of the emission of the SiO(5-4) and CO(3-2) molecular lines, including a new analysis of the optically thin 13CO(3-2) emission. In agreement with observations at shorter wavelengths, we give evidence for confinement of a dense gas volume within ∼50 au from the star and for a broad SiO line-width within ∼15 au… Expand
