cds-question@unistra.frinterstellar-mediuminterferometryprotostarsAtacama Large Millimeter/submillimeter Array (ALMA) observations of the high-mass star-forming region G35.20-0.74N have revealed the presence of a Keplerian disk in core B rotating about a massive object of 18M_{sun}_, as computed from the velocity field. The luminosity of such a massive star would be comparable to (or higher than) the luminosity of the whole star-forming region. To solve this problem it has been proposed that core B could harbor a binary system. This could also explain the possible precession of the radio jet associated with this core, which has been suggested by its S-shaped morphology. We establish the origin of the free-free emission from core B and investigate the existence of a binary system at the center of this massive core and the possible precession of the radio jet. We carried out VLA continuum observations of G35.20-0.74N at 2cm in the B configuration and at 1.3cm and 7mm in the A and B configurations. The bandwidth at 7mm covers the CH3OH maser line at 44.069GHz. Continuum images at 6 and 3.6cm in the A configuration were obtained from the VLA archive. We also carried out VERA observations of the H_2_O maser line at 22.235GHz.2016A&A...593A..49Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/593/A49CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/593/A49https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/593/A49http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/593/A49https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/593/A49https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/593/A49http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/593/A49GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/593/A49/list (List of fits images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/593/A49/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/593/A49/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/593/A49/list?GETtext/xml+votable180.050000true284.554291.676670.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/593/A496/30319https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/593/A49?format=asciidefaultJ/A+A/593/A49/listList of fits imagesrecnoRecord number assigned by the VizieR team.
