cds-question@unistra.frmultiple-starsinfrared-photometryvisible-astronomyphotometrystellar-distancestellar-spectral-typesstellar-associationsWe find a new substellar companion to the Pleiades member star, Pleiades HII 3441, using the Subaru telescope with adaptive optics. The discovery is made as part of the high-contrast imaging survey to search for planetary-mass and substellar companions in the Pleiades and young moving groups. The companion has a projected separation of 0.49+/-0.02 (66+/-2au) and a mass of 68+/-5MJ based on three observations in the J-, H-, and Ks-bands. The spectral type is estimated to be M7 (~2700K), and thus no methane absorption is detected in the H band. Our Pleiades observations result in the detection of two substellar companions including one previously reported among 20 observed Pleiades stars, and indicate that the fraction of substellar companions in the Pleiades is about 10.0^+26.1^_-8.8_%. This is consistent with multiplicity studies of both the Pleiades stars and other open clusters.2016PASJ...68...92Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASJ/68/92CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/259 : The Tycho-2 Catalogue (Hog+ 2000)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/297 : NOMAD Catalog (Zacharias+ 2005)J/A+A/299/696 : Pleiades field Membership probabilities (Schilbach+, 1995)J/A+A/323/139 : K magnitude of Pleiades low-mass binaries (Bouvier+ 1997)J/A+A/332/575 : Pleiades member list (Belikov+ 1998)J/AJ/123/1570 : alpha Persei and Praesepe Clusters (Patience+, 2002)J/A+A/400/891 : IZ photometry of Pleiades brown dwarfs (Moraux+, 2003)J/MNRAS/380/712 : ZYJHK photometry in Pleiades (Lodieu+, 2007)J/A+A/492/277 : Analysis of Collinder 69 stars with VOSA (Bayo+, 2008)J/ApJS/181/62 : Survey of young solar analogs (Metchev+, 2009)J/ApJS/208/9 : Intrinsic colors and temperatures of PMS stars (Pecaut+, 2013)J/ApJ/794/159 : Statistical analysis of exoplanet surveys (Brandt+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASJ/68/92https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASJ/68/92http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASJ/68/92https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASJ/68/92https://vizier.iucaa.in/viz-bin/votable?-source=J/PASJ/68/92http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASJ/68/92GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASJ/68/92/tables1 (Target list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASJ/68/92/tables1?https://vizier.iucaa.in/viz-bin/conesearch/J/PASJ/68/92/tables1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASJ/68/92/tables1?GETtext/xml+votable180.050000true20.134583-11.4676940.0055555555555555566/350 460 461 463 472 473 474 485 496 1875 6390 6420 11075 11145 15177 17486 17552 19027 23137 23774 24842 26614 28101 28341 404268.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASJ/68/92?format=asciiOpticalInfrareddefaultJ/PASJ/68/92/tables1Target listrecnoRecord number assigned by the VizieR team.
