cds-question@unistra.frinfrared-photometryeclipsing-binary-starsyoung-stellar-objectsWe present near-infrared JHK_S_ light curves for the double-lined eclipsing binary system Two Micron All Sky Survey J05352184-0546085, in which both components have been shown to be brown dwarfs with an age of ~1Myr. We analyze these light curves together with the previously published I_C_-band light curve and radial velocities to provide refined measurements of the system's physical parameters. The component masses and radii are here determined with an accuracy of ~6.5% and ~1.5%, respectively. In addition, we confirm the previous surprising finding that the primary brown dwarf has a cooler effective temperature than its lower mass companion. Our analysis reveals two low-amplitude (~0.02mag) periodic signals, one attributable to the rotation of the primary with a period of 3.293+/-0.001d and the other to the rotation of the secondary with a period of 14.05+/-0.05d. Both periods are consistent with the measured vsin i and radii.2009ApJ...699.1196Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/699/1196CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/664/1154 : Light curve of 2MASS J05352184-0546085 (Stassun+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/699/1196https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/699/1196http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/699/1196https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/699/1196https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/699/1196http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/699/1196GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/ApJ/699/1196/table2Differential J band light curve of 2M0535-05HJDHeliocentric Julian Datedtime.epochdoublerecnoRecord number assigned by the VizieR team.
