Abstract:
In this paper we present MASCARA-2 b, a hot Jupiter transiting the
mV=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±0.07RJ and place a 99 % upper limit on the
mass of <17MJ. HD 185603 is a rapidly rotating early-type star with
an effective temperature of 8980+90-130K and a mass and radius of
1.89+0.06-0.05Msun, 1.60±0.06Rsun, 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
λ=0.6±4°. 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.
Description:
Photometric time-series and radial velocities obtained for MASCARA-2
using the MASCARA, NITES, IAC80 and SONG telescopes. The MASCARA
photometry covers the period from February 2015 to December 2016 and
utilizes no filter. The NITES and IAC80 photometry was obtained during
the night of 4 June 2017 utilizing the R filter. The SONG RVs cover
the period from May-June 2017.
