cds-question@unistra.freclipsing-binary-starsvisible-astronomybroad-band-photometryradial-velocityCompact hierarchical systems are important because the effects caused by the dynamical interaction among its members occur ona human timescale. These interactions play a role in the formation of close binaries through Kozai cycles with tides. One such system is xi Tauri: it has three hierarchical orbits: 7.14d (eclipsing components Aa, Ab), 145d (components Aa+Ab, B), and 51yr (components Aa+Ab+B, C). We aim to obtain physical properties of the system and to study the dynamical interaction between its components. Our analysis is based on a large series of spectroscopic photometric (including space-borne) observations and long-baseline optical and infrared spectro-interferometric observations. We used two approaches to infer the system properties: a set of observation-specific models, where all components have elliptical trajectories, and an N-body model, which computes the trajectory of each component by integrating Newton's equations of motion.2016A&A...594A..55Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/594/A55CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/594/A55https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/594/A55http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/594/A55https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/594/A55https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/594/A55http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/594/A55GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap3.322582951404819e-19 6.118840631666147e-19OpticaldefaultJ/A+A/594/A55/tabled1Radial velocity measurementsrecnoRecord number assigned by the VizieR team.
