cds-question@unistra.fropen-star-clusterspre-main-sequence-starsx-ray-sourcesA recent observation of the Orion Nebula Cluster with the ACIS instrument on board the Chandra X-Ray Observatory detected 1075 sources, 525 of which are pre-main-sequence (PMS) stars with measured bulk properties such as bolometric luminosities, masses, ages, and disk indicators. Nearly half of these stars have photometrically measured rotational periods. This provides a uniquely large and well-defined sample to study the dependence of magnetic activity on bulk properties for stars descending the Hayashi tracks.2003ApJ...584..911Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/584/911CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/113/1733 : Orion Nebula Cluster population (Hillenbrand 1997)J/ApJ/437/361 : Einstein survey of the Orion nebula region (Gagne+ 1994)J/AJ/121/3160 : JHK photometry near the Trapezium region (Carpenter+, 2001)J/ApJ/574/258 : X-ray-emitting young stars in the Orion nebulahttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/584/911https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/584/911http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/584/911https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/584/911https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/584/911http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/584/911GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/584/911/table1 (X-ray properties of well-characterized ONC stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/584/911/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/584/911/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/584/911/table1?GETtext/xml+votable180.050000true83.658333-5.4611110.0055555555555555566/21438 21439 22804 22805https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/584/911?format=asciiX-raydefaultJ/ApJ/584/911/table1X-ray properties of well-characterized ONC starsrecnoRecord number assigned by the VizieR team.
