cds-question@unistra.frsolar-systemasteroidsIn this paper, we present a large-scale dynamical survey of the trans- Neptunian region, with particular attention to mean-motion resonances (MMRs). We study a set of 4121 trans-Neptunian objects (TNOs), a sample far larger than in previous works. We perform direct long-term numerical integrations that enable us to examine the overall dynamics of the individual TNOs as well as to identify all MMRs. For the latter purpose, we apply an own-developed FAIR method that allows the semi-automatic identification of even very high-order MMRs. Apart from searching for the more frequent eccentricity-type resonances that previous studies concentrated on, we set our method to allow the identification of inclination-type MMRs, too. Furthermore, we distinguish between TNOs that are locked in a given MMR throughout the whole integration time span (10^8^yr) and those that are only temporarily captured in resonances. For a more detailed dynamical analysis of the trans-Neptunian space, we also construct dynamical maps using test particles. Observing the fine structure of the 34-80au region underlines the stabilizing role of the MMRs, with the regular regions coinciding with the positions of real TNOs.2023ApJS..266....5Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/266/5CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/astorb : Orbits of Minor Planets (Bowell+ 2014)J/AJ/156/33 : Resonance sticking in population of scattering TNOs (Yu+, 2018)http://ssd.jpl.nasa.gov/horizons/ : JPL Horizons on-line solar system datahttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/266/5https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/266/5http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/266/5https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/266/5https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/266/5http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/266/5GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/ApJS/266/5/table1Summary of the resonant properties of trans-Neptunian objectsrecnoRecord number assigned by the VizieR team.
