cds-question@unistra.frpolarimetryh-ii-regionsinterstellar-mediumTo characterize the magnetic field structure of the outflow and core region within a prototypical high-mass star-forming region, we analyzed polarized CO(3-2) -for the first time observed with the Submillimeter Array- as well as 880um submillimeter continuum emission from the high-mass outflow/disk system IRAS 18089-1732. Both emission features with polarization degrees at a few percent level indicate that the magnetic field structure is largely aligned with the outflow/jet orientation from small core scales to larger outflow scales. Although quantitative estimates are crude, the analysis indicates that turbulent energy dominates over magnetic energy. The data also suggest a magnetic field strength increase from the lower-density envelope to the higher-density core.2010ApJ...724L.113Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/724/L113CatalogResearchIsServedByTAP VizieR generic servicerelated-toV/112 : Catalog of Star-Forming Regions in the Galaxy (Avedisova, 2002)II/225 : Catalog of Infrared Observations, Edition 5 (Gezari+ 1999)II/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)J/A+A/515/A42 : Catalog of high extinction clouds (Rygl+, 2010)J/other/PASA/26.439 : K-band images of star-forming regions (Longmore+, 2009)J/MNRAS/368/1223 : SCUBA observations of cold cores (Hill+, 2006)J/A+A/417/115 : High-mass protostellar candidates (Williams+, 2004)J/ApJ/566/945 : Massive star forming regions at 1.2mm (Beuther+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/724/L113https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/724/L113http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/724/L113https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/724/L113https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/724/L113http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/724/L113GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/724/L113/table1Polarization measurementsrecnoRecord number assigned by the VizieR team.
