Abstract:
We 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 mV=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±0.9MJ and 1.5±0.3RJ,
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/cm3 and an equilibrium temperature of 2570+50-30K,
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.
Description:
Photometric time-series obtained for MASCARA-1 using the MASCARA and
NITES telescopes. The MASCARA photometry covers the period from
February 2015 to September 2016 and utilizes no filter. The NITES
photometry was obtained during the nights of 23 July 2016 and 17
September 2016 utilizing the R and V filters, respectively.
