cds-question@unistra.frmultiple-starssolar-system-planetsphotometryspectroscopyexoplanetsIn this paper we present MASCARA-2 b, a hot Jupiter transiting the m_V_=7.6 A2 star HD 185603. Since early 2015, MASCARA has taken more than 1.6 million flux measurements of the star, corresponding to a total of almost 3000 hours of observations, revealing a periodic dimming in the flux with a depth of 1.3%. Photometric follow-up observations were performed with the NITES and IAC80 telescopes and spectroscopic measurements were obtained with the Hertzsprung SONG telescope. We find MASCARA-2 b orbits HD 185603 with a period of 3.474119^+0.000005^_-0.000006_ days at a distance of 0.057+/-0.006AU, has a radius of 1.83+/-0.07R_J_ and place a 99 % upper limit on the mass of <17M_J_. HD 185603 is a rapidly rotating early-type star with an effective temperature of 8980^+90^_-130_K and a mass and radius of 1.89^+0.06^_-0.05_M_sun_, 1.60+/-0.06R_sun_, respectively. Contrary to most other hot Jupiters transiting early-type stars, the projected planet orbital axis and stellar spin axis are found to be aligned with {lambda}=0.6+/-4{deg}. The brightness of the host star and the high equilibrium temperature, 2260+/-50K, of MASCARA-2 b make it a suitable target for atmospheric studies from the ground and space. Of particular interest is the detection of TiO, which has recently been detected in the similarly hot planets WASP-33 b and WASP-19 b.2018A&A...612A..57Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/612/A57CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/606/A73 : MASCARA-1 b (HD201585) light curves and spectra (Talens+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/612/A57https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/612/A57http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/612/A57https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/612/A57https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/612/A57http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/612/A57GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/612/A57/list (List of spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/612/A57/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/612/A57/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/612/A57/list?GETtext/xml+votable180.050000true294.6614231.219220.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/612/A576/14446https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/612/A57?format=asciidefaultJ/A+A/612/A57/nitesPhotometric time-series obtained by NITES during the night of 4 June 2017 using the R filterrecnoRecord number assigned by the VizieR team.
