Abstract:
We report the discovery of WASP-103 b, a new ultra-short-period
planet (P=22.2h) transiting a 12.1 V-magnitude F8-type main-sequence
star (1.22±0.04M☉, 1.44-0.03+0.05R☉,
Teff=6110±160K). WASP-103 b is significantly more massive
(1.49±0.09MJup) and larger (1.53-0.07+0.05RJup) than
Jupiter. Its large size and extreme irradiation (∼9x109erg/s/cm2)
make it an exquisite target for a thorough atmospheric
characterization with existing facilities. Furthermore, its orbital
distance is less than 20% larger than its Roche radius, meaning that
it might be significantly distorted by tides and might experience mass
loss through Roche-lobe overflow. It thus represents a new key object
for understanding the last stage of the tidal evolution of hot
Jupiters.
Description:
The host star WASP-103 (1SWASPJ163715.59+071100.0 =
2MASS16371556+0711000; V=12.1, K=10.8) was observed by the southern
station of the WASP survey during the 2010, 2011, and 2012 observing
seasons, covering the intervals 2010 May 15 to Aug. 16, 2011 Mar. 26
to Aug. 20, and 2012 Mar. 25 to Jun. 28.
