HAT-P-67b has a radius of R_p_=2.085_-0.071_^+0.096^ R_J_, and orbites a M_*_=1.642_-0.072_^+0.155^ M_{sun}_, R_*_=2.546_-0.084_^+0.099^ R_{sun}_ host star in a ~4.81 day period orbit. We place an upper limit on the mass of the planet via radial velocity measurements to be M_p_<0.59 M_J_, and a lower limit of >0.056 M_J_ by limitations on Roche lobe overflow. Despite being a subgiant, the host star still exhibits relatively rapid rotation, with a projected rotational velocity of vsini_*_=35.8+/-1.1 km/s, which makes it difficult to precisely determine the mass of the planet using radial velocities. We validated HAT-P-67b via two Doppler tomographic detections of the planetary transit, which eliminate potential eclipsing binary blend scenarios. The Doppler tomographic observations also confirm that HAT-P-67b has an orbit that is aligned to within 12{deg}, in projection, with the spin of its host star. HAT-P-67b receives strong UV irradiation and is among one of the lowest density planets known, which makes it a good candidate for future UV transit observations in the search for an extended hydrogen exosphere.2017AJ....153..211Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/153/211CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/128/1761 : HATNET variability survey (Hartman+, 2004)J/ApJ/704/1107 : Transiting planet candidates in HATNet field 205J/ApJ/710/1724 : Follow-up photometry for HAT-P-11 (Bakos+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/153/211https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/153/211http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/153/211https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/153/211https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/153/211http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/153/211GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfraredOpticaldefaultJ/AJ/153/211/table1Differential photometry of HAT-P-67recnoRecord number assigned by the VizieR team.
