HATS-70b has a mass of M_p_=12.9_-1.6_^+1.8^ M_Jup_ and a radius of R_p_=1.384_-0.074_^+0.079^ R_Jup_, residing in a close-in orbit with a period of 1.89 days. The host star is a M_*_=1.78+/-0.12 M_{sun}_ A star rotating at vsinI_*_=40.61_-0.35_^+0.32^ km/s, enabling us to characterize the spectroscopic transit of the brown dwarf via Doppler tomography. We find that HATS-70b, like other massive planets and brown dwarfs previously sampled, orbits in a low projected-obliquity orbit with {lambda}=8.9_-4.5_^+5.6o^. The low obliquities of these systems is surprising given all brown dwarf and massive planets with obliquities measured orbit stars hotter than the Kraft break. This trend is tentatively inconsistent with dynamically chaotic migration for systems with massive companions, though the stronger tidal influence of these companions makes it difficult to draw conclusions on the primordial obliquity distribution of this population. We also introduce a modeling scheme for planets around rapidly rotating stars, accounting for the influence of gravity darkening on the derived stellar and planetary parameters.2019AJ....157...31Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/157/31CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/146/113 : Differential griz photometry of HATS-3 (Bayliss+, 2013)J/AJ/147/144 : Differential griz photometry of HATS-5 (Zhou+, 2014)J/AJ/148/29 : Spectroscopy and differential photometry of HATS-4J/AJ/149/166 : Photometry and spectroscopy of HATS-6 (Hartman+, 2015)J/AJ/150/33 : Photometry and spectroscopy of HATS-9 and HATS-10J/AJ/150/49 : Photometry and spectroscopy of HATS-8 (Bayliss+, 2015)J/ApJ/813/111 : Differential photometry of the K dwarf HATS-7 (Bakos+, 2015)J/AJ/151/89 : Spectroscopy and photometry of HATS-17 (Brahm+, 2016)J/AJ/152/88 : Spectroscopy and photometry of HATS-11 and HATS-12J/AJ/152/161 : Photometry for HATS-31 through HATS-35 (de Val-Borro+, 2016)J/AJ/155/112 : Radial velocities + light curves for HATS-43-HATS-46J/AJ/156/216 : Differential photometry + RVs of HATS-59 (Sarkis+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/157/31https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/157/31http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/157/31https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/157/31https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/157/31http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/157/31GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AJ/157/31/table2Differential photometry of HATS-70recnoRecord number assigned by the VizieR team.
