cds-question@unistra.frinfrared-sourcesmillimeter-astronomysubmillimeter-astronomyinterferometryHigh-mass stars have a high degree of multiplicity and most likely form via disk accretion processes. The detailed physics of the binary and disk formation are still poorly constrained. We seek to resolve the central substructures of the prototypical high-mass star-forming region NGC7538IRS1 at the highest possible spatial resolution line and continuum emission to investigate the protostellar environment and kinematics. Using the Karl G. Jansky Very Large Array (VLA) in its most extended configuration at ~24GHz has allowed us to study the NH_3_ and thermal CH_3_OH emission and absorption as well as the cm continuum emission at an unprecedented spatial resolution of 0.06"x0.05", corresponding to a linear resolution of ~150AU at a distance of 2.7kpc.2017A&A...605A..61Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/605/A61CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/558/A81 : NGC 7538 IRS1 maps in CH3OH, HCN and HCO+ (Beuther+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/605/A61https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/605/A61http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/605/A61https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/605/A61https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/605/A61http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/605/A61GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/605/A61/list (List of fits files)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/605/A61/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/605/A61/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/605/A61/list?GETtext/xml+votable180.050000true348.43961.469640.0055555555555555566/14317https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/605/A61?format=asciiInfraredRadiodefaultJ/A+A/605/A61/listList of fits filesrecnoRecord number assigned by the VizieR team.
