cds-question@unistra.frvariable-starspre-main-sequence-starsinfrared-photometryWe present an analysis of J, H, and Ks time-series photometry obtained with the southern 2MASS telescope over a 0.84{deg}x6{deg} region centered near the Trapezium region of the Orion Nebula cluster. These data are used to establish the near-infrared variability properties of premain-sequence stars in Orion on timescales of ~1-36days, ~2 months, and ~2 years. A total of 1235 near-infrared variable stars are identified, ~93% of which are likely associated with the Orion A molecular cloud.2001AJ....121.3160Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/121/3160CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/121/3160https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/121/3160http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/121/3160https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/121/3160https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/121/3160http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/121/3160GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/121/3160/table4 (Near-Infrared Variable Stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/121/3160/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/121/3160/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/121/3160/table4?GETtext/xml+votable180.050000true83.41033611-6.000066940.0055555555555555566/21424 21426-21427 21432-21433 21435-21436 21438-21439 22804-22805 22807 22848 22850-22851 22856-22857https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/121/3160?format=asciiInfrareddefaultJ/AJ/121/3160/table4Near-Infrared Variable StarsFlag3[0/1] Long-term variability in 2000 February and/or 1998 March (1)meta.codeintrecnoRecord number assigned by the VizieR team.
