cds-question@unistra.frmultiple-starssolar-system-planetsphotometryspectroscopyWe report the discovery of MASCARA-1 b, the first exoplanet discovered with the Multi-site All-Sky CAmeRA (MASCARA). It is a hot Jupiter orbiting a bright m_V_=8.3, rapidly rotating (vsini>100km/s) A8 star with a period of 2.148780+/-0.000008 days. The planet has a mass and radius of 3.7+/-0.9M_J_ and 1.5+/-0.3R_J_, respectively. As with most hot Jupiters transiting early-type stars we find a misalignment between the planet orbital axis and the stellar spin axis, which may be signature of the formation and migration histories of this family of planets. MASCARA-1 b has a mean density of 1.5+/-0.9g/cm^3^ and an equilibrium temperature of 2570^+50^_-30_K, one of the highest temperatures known for a hot Jupiter to date. The system is reminiscent of WASP-33, but the host star lacks apparent delta-scuti variations, making the planet an ideal target for atmospheric characterization. We expect this to be the first of a series of hot Jupiters transiting bright early-type stars that will be discovered by MASCARA.2017A&A...606A..73Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/606/A73CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/606/A73https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/606/A73http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/606/A73https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/606/A73https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/606/A73http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/606/A73GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapAssociated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/606/A73defaultJ/A+A/606/A73/mascaraPhotometric time-series obtained with MASCARA over the period from February 2015 to September 2016recnoRecord number assigned by the VizieR team.
