cds-question@unistra.fropen-star-clusterseclipsing-binary-starsyoung-stellar-objectsinfrared-photometryThe Palomar Transient Factory (PTF) Orion project is one of the experiments within the broader PTF survey, a systematic automated exploration of the sky for optical transients. Taking advantage of the wide (3.5{deg}x2.3{deg}) field of view available using the PTF camera installed at the Palomar 48 inch telescope, 40 nights were dedicated in 2009 December to 2010 January to perform continuous high-cadence differential photometry on a single field containing the young (7-10Myr) 25 Ori association. Little is known empirically about the formation of planets at these young ages, and the primary motivation for the project is to search for planets around young stars in this region. The unique data set also provides for much ancillary science. In this first paper, we describe the survey and the data reduction pipeline, and present some initial results from an inspection of the most clearly varying stars relating to two of the ancillary science objectives: detection of eclipsing binaries and young stellar objects.2011AJ....142...60Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/142/60CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/129/907 : New Ori OB1 members (Briceno+, 2005)J/ApJ/661/1119 : Spectroscopy in the 25 Ori group (Briceno+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/142/60https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/142/60http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/142/60https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/142/60https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/142/60http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/142/60GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/142/60/table1 (New eclipsing binaries from the PTF Orion data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/142/60/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/142/60/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/142/60/table1?GETtext/xml+votable180.050000true80.266482.674260.005555555555555556Cone search capability for table J/AJ/142/60/table3 (Candidate CTTSs: sources with irregular light curves and {Delta}R~1.0mag or more)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/142/60/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/142/60/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/142/60/table3?GETtext/xml+votable180.050000true81.07592.28890.0055555555555555565/5723 5726 6/22887 22891 22898 22980 22981 22983 229928.27688880188539e-21 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/142/60?format=asciiInfrareddefaultJ/AJ/142/60/table1New eclipsing binaries from the PTF Orion datarecnoRecord number assigned by the VizieR team.
