cds-question@unistra.fropen-star-clusterspre-main-sequence-starsvisible-astronomykron-cousins-photometryThe extremely young cluster IC 348 has been monitored photometrically over five observing seasons from 1998 December 10 to 2003 March 26 in Cousins I with a 0.6m telescope at Van Vleck Observatory. Twenty-eight periodic variables and 16 irregular variables have been identified. The variability study is most sensitive for stars with I<14.3mag; at that brightness level, we find that 24 of the 27 known pre-main-sequence (PMS) cluster members in the monitored field are variables, illustrating the value of photometric monitoring for identifying PMS cluster members. Among this brighter sample, 14 of the 16 known K or M-type weak-line T Tauri stars (WTTS) were found to be periodic variables, while all five of the known classical T Tauri stars (CTTS) were found to be irregular variables. In the full sample, which includes 150 stars with I as faint as 18, we find that 40% of the 63 WTTS are detected as variables, nearly all of them periodic, while 55% of the 20 CTTS are also detected as variable, with none of them periodic.2004AJ....127.1602Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/127/1602CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/409/147 : J magnitude of IC 348 brown dwarfs (Preibisch+, 2003)J/ApJ/597/555 : IR photometry of IC 348 young brown dwarfs (Mainzer+, 2003)J/AJ/122/866 : X-ray sources in IC 348 from Chandra (Preibisch+, 2001)J/ApJ/541/977 : HST observations of low-mass stars in IC 348 (Najita+, 2000)J/ApJ/497/736 : The young cluster IC 348 (Herbig, 1998)J/A+A/324/549 : Deep UVBRI photometry in IC 348 (Trullols+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/127/1602https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/127/1602http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/127/1602https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/127/1602https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/127/1602http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/127/1602GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/127/1602/table2 (Variability properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/1602/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/1602/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/1602/table2?GETtext/xml+votable180.050000true56.142458332.16277780.0055555555555555566/1539https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/127/1602?format=asciiOpticaldefaultJ/AJ/127/1602/table2Variability propertiesrecnoRecord number assigned by the VizieR team.
