cds-question@unistra.frnebulaemolecular-cloudsWe present continuum and molecular line emission ALMA observations of OH 231.8+4.2, a well studied bipolar nebula around an asymptotic giant branch (AGB) star. The high angular resolution (~0.2"-0.3") and sensitivity of our ALMA maps provide the most detailed and accurate description of the overall nebular structure and kinematics of this object to date. We have identified a number of outflow components previously unknown. Species studied in this work include ^12^CO, ^13^CO, CS, SO, SO_2_, OCS, SiO, SiS, H_3_O^+^, Na^37^Cl, and CH_3_OH. The molecules Na^37^Cl and CH_3_OH are first detections in OH 231.8+4.2, with CH_3_OH being also a first detection in an AGB star.2018A&A...618A.164Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/618/A164CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/618/A164https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/618/A164http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/618/A164https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/618/A164https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/618/A164http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/618/A164GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/618/A164/list (List of fits files)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/618/A164/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/618/A164/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/618/A164/list?GETtext/xml+votable180.050000true115.57047-14.713910.0055555555555555566/21523https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/618/A164?format=asciidefaultJ/A+A/618/A164/listList of fits filesNxNumber of pixels along X-axismeta.numberintNz?
