The newly discovered BD is EPIC 212036875b and the low-mass star is KOI-607b. EPIC 212036875b has a mass of M_b_=52.3+/-1.9 M_J_, a radius of R_b_=0.874+/-0.017 R_J_, and orbits its host star in P=5.169885+/-0.000027 days. Its host star is a late F-type star with M_*_=1.288+/-0.065 M_{sun}_, R_*_= 1.498+/-0.025 R_{sun}_, and T_eff_=6238+/-60 K. KOI-607b has a mass of M_b_=95.1+/-3.4 M_J_, a radius of R_b_=1.089+/-0.089 R_J_, and an orbital period of P=5.89399148+/-0.00000060 days. The primary star in the KOI-607 system is a G dwarf with M_*_=0.993+/-0.052 M_{sun}_, R_*_= 0.915+/-0.031 R_{sun}_, and T_eff_=5418+/-87 K. We also revisit a BD, CWW 89Ab, that was previously published by Nowak et al. 2017AJ....153..131N (under the designation EPIC 219388192b). CWW 89Ab is one of two known transiting BDs associated with a star cluster, which illustrates the need for more BDs with accurate masses, radii, and reliable age determinations to test theoretical models. We find that the newly discovered BD, EPIC 212036875b, falls in the middle of the so-called BD desert, indicating that EPIC 212036875b is either a particularly rare object, or the BD desert may not be so dry after all.2019AJ....158...38Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/158/38CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)J/ApJ/683/1076 : Transits of exoplanet XO-3b (Winn+, 2008)J/ApJ/718/1353 : Light curve of the triple system NLTT 41135 (Irwin+, 2010)J/ApJ/761/123 : KELT-1 photometry and spectroscopy follow-up (Siverd+, 2012)J/AJ/153/15 : Photometry and spectroscopy of EPIC 201702477 (Bayliss+, 2017)J/A+A/628/A64 : EPIC 212036875b griz light curves (Persson+, 2019)J/AJ/157/31 : Differential photometry & radial velocities of HATS-70https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/158/38https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/158/38http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/158/38https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/158/38https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/158/38http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/158/38GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/158/38/BDs (List of published transiting brown dwarfs as of March 2019 (table 7) and additional information (table 8))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/158/38/BDs?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/158/38/BDs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/158/38/BDs?GETtext/xml+votable180.050000true147.769083335.96929720.0055555555555555566/3344 4698 4866 5659 14762 14764 14780 14931 15137 15148 17300 20476 21438 23620 27005 29045 30293 30439 31450 38246 39826 443911.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/158/38?format=asciidefaultJ/AJ/158/38/BDsList of published transiting brown dwarfs as of March 2019 (table 7) and additional information (table 8)SimbadNameSimbad column added by the CDSmeta.idcharNameSystem identifiermeta.id;pos.framecharl_eLimit flag on emeta.code.errorcharR[0.757/6.5] Brown dwarf radius(7.1492x10+7m)phys.size.radiusfloatBibcode2Bibcode of the referencemeta.bib.bibcodecharrecnoRecord number assigned by the VizieR team.
