We observed the carbon-rich asymptotic giant branch (AGB) star TX Piscium (TX Psc) with ALMA in CO(2-1) emission to investigate the circumstellar envelope (CSE) and mass-loss history of this object. Previous observations with Herschel in the far infrared have shown a ring-like structure in dust emission (2011A&A...532A.135J). Our molecular gas observations of the CO(2-1) emission line cover this structure with significantly higher spatial resolution to investigate its origin.
