cds-question@unistra.frapparent-magnitudephotometrystellar-associationsWe make use of new near- and mid-IR photometry of the Pleiades cluster in order to help identify proposed cluster members. We also use the new photometry with previously published photometry to define the single-star main-sequence locus at the age of the Pleiades in a variety of color-magnitude planes. The new near- and mid-IR photometry extend effectively 2 mag deeper than the 2MASS All-Sky Point Source catalog, and hence allow us to select a new set of candidate very low-mass and substellar mass members of the Pleiades in the central square degree of the cluster. We identify 42 new candidate members fainter than K_s_=14 (corresponding to 0.1M_{sun}_). These candidate members should eventually allow a better estimate of the cluster mass function to be made down to of order 0.04M_{sun}_. We also use new IRAC data, in particular the images obtained at 8um, in order to comment briefly on interstellar dust in and near the Pleiades.2007ApJS..172..663Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/172/663CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/258 : Pleiades positions and proper motions (Wang+, 1996)J/A+AS/100/607 : Pleiades very low mass proper motion members (Hambly+, 1993)J/A+A/299/696 : Pleiades field Membership probabilities (Schilbach+, 1995)J/A+A/320/74 : Radial velocities of Pleiades members (Mermilliod+ 1997)J/A+A/332/575 : Pleiades member list (Belikov+ 1998)J/MNRAS/313/347 : Pleiades low-mass stars and brown dwarfs (Pinfield+, 2000)J/A+A/416/125 : RI photometry in alpha Per and Pleiades (Deacon+, 2004)J/AJ/132/2665 : QUEST2 BRI photometry of Taurus-Auriga PMS (Slesnick+, 2006)http://irsa.ipac.caltech.edu : 2MASS 6x database accesshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/172/663https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/172/663http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/172/663https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/172/663https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/172/663http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/172/663GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/172/663/table5 (New candidate Pleiades members)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/172/663/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/172/663/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/172/663/table5?GETtext/xml+votable180.050000true56.1574524.427460.005555555555555556Cone search capability for table J/ApJS/172/663/table2 (Pleiades members: literature photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/172/663/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/172/663/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/172/663/table2?GETtext/xml+votable180.050000true51.8982730624.528660.0055555555555555563/7 5/91 94 6/319 359 361 362 363 382 405 407 437 439 836 837 848 849 1160 11623.036429446233786e-20 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/172/663?format=asciiOpticaldefaultJ/ApJS/172/663/table5New candidate Pleiades membersJmag2MASS J band magnitudemagphot.mag;em.IR.JfloatrecnoRecord number assigned by the VizieR team.
