cds-question@unistra.frmultiple-starsradial-velocityvisible-astronomysloan-photometrysolar-system-planetsWe report the discovery of HAT-P-30b, a transiting exoplanet orbiting the V=10.419 dwarf star GSC 0208-00722. The planet has a period P=2.810595+/-0.000005 days, transit epoch T_c_=2455456.46561+/-0.00037 (BJD), and transit duration 0.0887+/-0.0015 days. The host star has a mass of 1.24+/-0.04M_{sun}_, radius of 1.21+/-0.05R_{sun}_, effective temperature of 6304+/-88K, and metallicity [Fe/H]=+0.13+/-0.08. The planetary companion has a mass of 0.711+/-0.028M_J_ and radius of 1.340+/-0.065R_J_ yielding a mean density of 0.37+/-0.05g/cm^3^. We also present radial velocity measurements that were obtained throughout a transit that exhibit the Rossiter-McLaughlin effect. By modeling this effect, we measure an angle of {lambda}=73.5+/-9.0{deg} between the sky projections of the planet's orbit normal and the star's spin axis. HAT-P-30b represents another example of a close-in planet on a highly tilted orbit, and conforms to the previously noted pattern that tilted orbits are more common around stars with T_eff*_>~6250K.2011ApJ...735...24Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/735/24CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/MNRAS/422/2024 : X-ray-age relation & exoplanet evaporation (Jackson+, 2012)J/ApJ/725/875 : Chromospheric activity for CPS stars (Isaacson+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/735/24https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/735/24http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/735/24https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/735/24https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/735/24http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/735/24GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/735/24/table1Relative radial velocities, bisector spans, and activity index measurements of HAT-P-30PhasePhasetime.phasefloatrecnoRecord number assigned by the VizieR team.
