cds-question@unistra.frmultiple-starsspectroscopyStable shell stars are ideal objects for studying basic physical principles of the formation of disks in Be stars. If these stars have a close unresolved visual companion, its contribution toward the modelling of the disk cannot be overlooked, as is sometimes done. The study aims to spectroscopically resolve close visual binary Be (shell) star 1 Del, which up to now was only resolved by speckle or micrometric measurements. The integral field spectroscopy obtained by the SINFONI spectrograph at the VLT telescope in the European Southern Observatory (ESO) in the infrared region was used; we supplemented these observations with visual spectroscopy with the Perek Telescope at the Ondrejov Observatory. Spectra of 1 Del were successfully resolved, and, for the first time, spectra of 1 Del B were obtained. We found that 1 Del A is a Be/shell star, while 1 Del B is not an emission-line object.2016A&A...587A..22Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/587/A22CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/587/A22https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/587/A22http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/587/A22https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/587/A22https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/587/A22http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/587/A22GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/587/A22/list (List of fits files)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/587/A22/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/587/A22/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/587/A22/list?GETtext/xml+votable180.050000true307.5753210.896460.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/587/A226/12461https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/587/A22?format=asciiOpticaldefaultJ/A+A/587/A22/listList of fits filesObs.DateObservation datetime.epoch;obscharNz?
