cds-question@unistra.frmultiple-starslate-type-starsinterferometryBinary post-asymptotic giant branch (post-AGB) stars are interesting laboratories to study both the evolution of binaries as well as the structure of circumstellar disks. A multiwavelength high angular resolution study of the prototypical object 89 Herculis is performed with the aim of identifying and locating the different emission components seen in the spectral energy distribution. A large interferometric data set, collected over the past decade and covering optical and near-infrared wavelengths, is analyzed in combination with the spectral energy distribution and flux-calibrated optical spectra. In this first paper only simple geometric models are applied to fit the interferometric data. Combining the interferometric constraints with the photometry and the optical spectra, we re-assess the energy budget of the post-AGB star and its circumstellar environment.2013A&A...559A.111Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/559/A111CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/559/A111https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/559/A111http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/559/A111https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/559/A111https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/559/A111http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/559/A111GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/559/A111/listList of OI-FITS filesrecnoRecord number assigned by the VizieR team.
