cds-question@unistra.fropen-star-clustersstellar-associationsinfrared-photometryvisible-astronomybroad-band-photometryWe present new BVI_C_ photometry for 350 Pleiades proper motion members with 9<V<~17. Importantly, our new catalog includes a large number of K- and early M-type stars, roughly doubling the number of low-mass stars with well-calibrated Johnson/Cousins photometry in this benchmark cluster. We combine our new photometry with existing photometry from the literature to define a purely empirical isochrone at Pleiades age ({approx}100Myr) extending from V=9 to 17. We use the empirical isochrone to identify 48 new probable binaries and 14 likely nonmembers. The photometrically identified single stars are compared against their expected positions in the color-magnitude diagram (CMD). At 100Myr, the mid K and early M stars are predicted to lie above the zero-age main sequence (ZAMS) having not yet reached the ZAMS. We find in the B-V versus V CMD that mid K and early M dwarfs are instead displaced below (or blueward of) the ZAMS. Using the stars' previously reported rotation periods, we find a highly statistically significant correlation between rotation period and CMD displacement, in the sense that the more rapidly rotating stars have the largest displacements in the B-V CMD.2014AJ....148...30Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/148/30CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/258 : Pleiades positions and proper motions (Wang+, 1996)II/131 : Tonantzintla Pleiades Flare Stars (Haro+ 1982)J/MNRAS/422/1495 : UKIDSS Galactic Clusters Survey Pleiades membersJ/MNRAS/408/475 : HATNet Pleiades Rotation Period Catalogue (Hartman+, 2010)J/MNRAS/380/712 : ZYJHK photometry in Pleiades (Lodieu+, 2007)J/ApJS/172/663 : Infrared observations of the Pleiades (Stauffer+, 2007)J/A+A/416/125 : RI photometry in alpha Per and Pleiades (Deacon+, 2004)J/MNRAS/313/347 : Pleiades low-mass stars and brown dwarfs (Pinfield+, 2000)J/A+A/329/101 : Masses of Pleiades members (Raboud+ 1998)J/A+A/337/403 : Low-mass stars evolutionary models (Baraffe+ 1998)J/A+A/335/183 : Pleiades low-mass stars rotational velocities (Queloz+ 1998)J/A+A/332/575 : Pleiades member list (Belikov+ 1998)J/A+A/323/139 : K magnitude of Pleiades low-mass binaries (Bouvier+ 1997)J/A+A/320/74 : Radial velocities of Pleiades members (Mermilliod+ 1997)J/A+A/299/696 : Pleiades field Membership probabilities (Schilbach+, 1995)J/A+AS/100/607 : Pleiades very low mass proper motion members (Hambly+, 1993)J/ApJS/85/315 : F, G and K dwarf stars of the Pleiades (Soderblom+ 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/148/30https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/148/30http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/148/30https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/148/30https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/148/30http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/148/30GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/148/30/table1 (New BVIc Pleiades photometry (corrected version sent by the author))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/148/30/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/148/30/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/148/30/table1?GETtext/xml+votable180.050000true59.219708320.08360.0055555555555555564/28 5/91 116 118 121 122 123 124 6/319 359 361 362 363 378 382 405 407 437 469 470 471 476 478 480 481 483 500 504 506 507 508 509 510 836 848 11603.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/148/30?format=asciiInfraredOpticaldefaultJ/AJ/148/30/table1New BVIc Pleiades photometry (corrected version sent by the author)SimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
