MASCARA News and Results - Finding transiting planets around early-type stars

The Multi-site All-sky CAmeRA MASCARA is an instrument concept consisting of several stations across the globe, with each station containing a battery of low-cost cameras to monitor the near-entire sky at each location. Once all stations have been installed, MASCARA will be able to provide a nearly 24-hr coverage of the complete dark sky, down to magnitude 8, at sub-minute cadence. Its purpose is to find the brightest transiting exoplanet systems, expected in the V=4-8 magnitude range - currently not probed by space- or ground-based surveys. The bright/nearby transiting planet systems, which MASCARA will discover, will be the key targets for detailed planet atmosphere observations. We present studies on the initial design of a MASCARA station, including the camera housing, domes, and computer equipment, and on the photometric stability of low-cost cameras showing that a precision of 0.3-1% per hour can be readily achieved. We plan to roll out the first MASCARA station before the end of 2013. A 5-station MASCARA can within two years discover up to a dozen of the brightest transiting planet systems in the sky.

Was wondering if I'd missed MASCARA-1b. The MASCARA-2b paper indicates there is a forthcoming paper (Talens et al. 2017b, A&A Submitted), and the discussion indicates that it also orbits an early-type star. I'm guessing this one came out first because the KELT team also discovered the planet.

MASCARA-1 b: A hot Jupiter transiting a bright mV=8.3 A-star in a misaligned orbit
https://arxiv.org/abs/1707.04262

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⋆>100 km s−1) A8 star with a period of 2.148780񸋵0−6 days. The planet has a mass and radius of 3.70.9 MJup and 1.50.3 RJup, 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 1.50.9 g 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.

The host star is HD 201585.
I've taken the original MASCARA thread and re-dedicated it to further news and developments to help with housekeeping. Smile
