cds-question@unistra.frearly-type-starsmagnetic-fieldsThe detection of bright, hard, and variable X-ray emission in Tr16-22 prompted spectropolarimetric observations of this star, which in turn led to the discovery of a surface magnetic field. We want to further constrain the properties of this star, in particular to verify whether X-ray variations are correlated to changes in optical emission lines and magnetic field strength, as expected from the oblique rotator model that is widely accepted for magnetic O stars. We have obtained new low-resolution spectropolarimetric and long-term high-resolution spectroscopic monitoring of Tr16-22, and we also analyse new, serendipitous X-ray data.2016A&A...596A..44Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/596/A44CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/596/A44https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/596/A44http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/596/A44https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/596/A44https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/596/A44http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/596/A44GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/596/A44/listList of observation filesrecnoRecord number assigned by the VizieR team.
