cds-question@unistra.frsolar-system-planetsmultiple-starsphotometrydwarf-starsm-starsradial-velocityWe report the discovery by the HATSouth survey of HATS-6b, an extrasolar planet transiting a V=15.2mag, i=13.7mag M1V star with a mass of 0.57M_{Sun}_ and a radius of 0.57R_{sun}_ . HATS-6b has a period of P=3.3253d, mass of M_p_=0.32M_J_, radius of R_p_=1.00R_J_, and zero-albedo equilibrium temperature of T_eq_=712.8+/-5.1K. HATS-6 is one of the lowest mass stars known to host a close-in gas giant planet, and its transits are among the deepest of any known transiting planet system. We discuss the follow-up opportunities afforded by this system, noting that despite the faintness of the host star, it is expected to have the highest K-band S/N transmission spectrum among known gas giant planets with T_eq_<750K. In order to characterize the star we present a new set of empirical relations between the density, radius, mass, bolometric magnitude, and V-, J-, H- and K-band bolometric corrections for main sequence stars with M<0.80M_{Sun}_, or spectral types later than K5. These relations are calibrated using eclipsing binary components as well as members of resolved binary systems. We account for intrinsic scatter in the relations in a self-consistent manner. We show that from the transit-based stellar density alone it is possible to measure the mass and radius of a ~0.6M_{Sun}_ star to ~7 and ~2% precision, respectively. Incorporating additional information, such as the V-K color, or an absolute magnitude, allows the precision to be improved by up to a factor of two.2015AJ....149..166Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/149/166CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/149/149 : Photometry and spectroscopy of HAT-P-54 (Bakos+, 2015)J/A+A/562/A126 : Light curves of WASP-80 transit events (Mancini+, 2014)J/AJ/148/29 : Spectroscopy and photometry of HATS-4 (Jordan+, 2014)J/A+A/558/A55 : HATS-2b griz light curves (Mohler-Fischer+, 2013)J/AJ/146/113 : Differential griz photometry of HATS-3 (Bayliss+, 2013)J/AJ/145/5 : Follow-up photometry of HATS-1 (Penev+, 2013)J/AJ/144/139 : HAT-P-39, HAT-P-40, and HAT-P-41 follow-up (Hartman+, 2012)J/AJ/144/19 : Follow-up photometry for HAT-P-34--HAT-P-37 (Bakos+, 2012)J/AJ/141/166 : HATNet variability survey of K and M dwarfs (Hartman+, 2011)J/ApJ/710/1724 : Follow-up photometry for HAT-P-11 (Bakos+, 2010)J/ApJ/701/764 : Light curves for five M-dwarf stars (Fernandez+, 2009)http://www.hatsouth.org/ : HATSouth websitehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/149/166https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/149/166http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/149/166https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/149/166https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/149/166http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/149/166GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/149/166/table2Differential photometry of HATS-6recnoRecord number assigned by the VizieR team.
