cds-question@unistra.frmultiple-starsexoplanetsradial-velocityapparent-magnitudeWe report the discovery of MASCARA-3b, a hot Jupiter orbiting its bright (V=8.33) late F-type host every 5.55149+/-0.00001-days in an almost circular orbit (e=0.050^+0.020^_-0.017_). This is the fourth exoplanet discovered with the Multi-site All-Sky CAmeRA (MASCARA), and the first of these that orbits a late-type star. Follow-up spectroscopic measurements were obtained in and out of transit with the Hertzsprung SONG telescope. Combining the MASCARA photometry and SONG radial velocities reveals a radius and mass of 1.36+/-0.05R_Jup_ and 4.2+/-0.2M_Jup_. In addition, SONG spectroscopic transit observations were obtained on two separate nights. From analyzing the mean out-of-transit broadening function, we obtain vsini*=20.4+/-0.4km/s. In addition, investigating the Rossiter-McLaughlin effect, as observed in the distortion of the stellar lines directly and through velocity anoma lies, we find the projected obliquity to be {lambda}=1.2^+8.2^_-7.4_deg, which is consistent with alignment.2019A&A...631A..76Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/631/A76CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/606/A73 : MASCARA-1 b (HD201585) light curves & spectra (Talens+, 2017)J/A+A/612/A57 : MASCARA-2 b (HD185603) light curves & spectra (Talens+, 2018)J/A+A/616/A151 : MASCARA-2b NaI + Ha absorption lines (Casasayas-Barris+, 2018)J/A+A/628/A9 : MASCARA-2b transmission spectra (Casasayas-Barris+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/631/A76https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/631/A76http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/631/A76https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/631/A76https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/631/A76http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/631/A76GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/631/A76/tablea1*Radial velocities at times out of transit for MASCARA-3 using the SONG telescoperecnoRecord number assigned by the VizieR team.
