cds-question@unistra.frbe-starsmagnetic-fieldsOne hundred and twenty-five new high-precision spectropolarimetric observations have been obtained with ESPaDOnS (Eschelle Spectro-Polarimetric Device for the Observation of Stars) at the Canada-France-Hawaii Telescope and Narval at Telescope Bernard Lyot to investigate the magnetic properties of the classical Be star omega Ori. No Stokes V signatures are detected in our polarimetric data. Measurements of the longitudinal magnetic field, with a median error bar of 30G, and direct modelling of the mean least-squares deconvolved Stokes V profiles yield no evidence for a dipole magnetic field with polar surface strength greater than ~80G.2012MNRAS.426.2738Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/426/2738CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/409/275 : Rotation and magnetic field in omega Ori (Neiner+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/426/2738https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/426/2738http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/426/2738https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/426/2738https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/426/2738http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/426/2738GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/426/2738/table1Magnetic measurements of {omega} OrirecnoRecord number assigned by the VizieR team.
