cds-question@unistra.frinterstellar-mediumastrophysical-masersradio-astronomyHigh-mass star formation remains poorly understood due to observational difficulties (e.g. high dust extinction and large distances) hindering the resolution of disk-accretion and out ow-launching regions. Orion Source I is the closest known massive young stellar object (YSO) and exceptionally powers vibrationally excited SiO masers at radii within 100AU, providing a unique probe of gas dynamics and energetics. We seek to observe and image these masers with Very Long Baseline Interferometry (VLBI). We present the first images of the ^28^SiO v=1, J=2-1 maser emission around Orion Source I observed at ({lambda}2mm) with the Very Long Baseline Array (VLBA). These images have high spatial (~0.3mas) and spectral (~0.054km/s) resolutions.2017A&A...606A.126Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/606/A126CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/606/A126https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/606/A126http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/606/A126https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/606/A126https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/606/A126http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/606/A126GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/606/A126/list (Informations on fits file)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/606/A126/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/606/A126/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/606/A126/list?GETtext/xml+votable180.050000true83.81048-5.375190.0055555555555555566/21439https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/606/A126?format=asciiRadiodefaultJ/A+A/606/A126/listInformations on fits fileTitleTitle of the FITS filemeta.title;meta.fitscharNzNumber of pixels along Z-axismeta.numberintrecnoRecord number assigned by the VizieR team.
