A spectroscopic study of the open cluster NGC 6250
A. J. Martin, M. J. Stift, L. Fossati +4
We present the chemical abundance analysis of 19 upper main-sequence stars of the young open cluster NGC 6250 (log t ~ 7.42 yr). This work is part of a project aimed at setting obs…
Peculiar architectures for the WASP-53 and WASP-81 planet-hosting systems
Amaury H. M. J. Triaud, Marion Neveu-VanMalle, Monika Lendl +16
We report the detection of two new systems containing transiting planets. Both were identified by WASP as worthy transiting planet candidates. Radial-velocity observations quickly…
WASP-20 is a close visual binary with a transiting hot Jupiter
Daniel Evans, John Southworth, Barry Smalley
We announce the discovery that WASP-20 is a binary stellar system, consisting of two components separated by on the sky, with a flux ratio of $0.46…
Rossiter--McLaughlin models and their effect on estimates of stellar rotation, illustrated using six WASP systems
D. J. A. Brown, A. H. M. J. Triaud, A. P. Doyle +12
We present new measurements of the projected spin--orbit angle for six WASP hot Jupiters, four of which are new to the literature (WASP-61, -62, -76, and -78), and two of which…
WASP-86b and WASP-102b: super-dense versus bloated planets
F. Faedi, Y. Gómez Maqueo Chew, D. Pollacco +38
We report the discovery of two transiting planetary systems: a super dense, sub-Jupiter mass planet WASP-86b (\mpl\ = 0.82 0.06 \mj, \rpl\ = 0.63 0.01 \rj), and a bloat…
HD 24355 observed by the Kepler K2 mission: A rapidly oscillating Ap star pulsating in a distorted quadrupole mode
Daniel L. Holdsworth, Donald W. Kurtz, Barry Smalley +4
We present an analysis of the first Kepler K2 mission observations of a rapidly oscillating Ap (roAp) star, HD 24355 (). The star was discovered in SuperWASP broadband phot…
Discovery of WASP-113b and WASP-114b, two inflated hot-Jupiters with contrasting densities
S. C. C. Barros, D. J. A. Brown, G. Hébrard +37
We present the discovery and characterisation of the exoplanets WASP-113b and WASP-114b by the WASP survey, {\it SOPHIE} and {\it CORALIE}. The planetary nature of the systems was…
WASP-92b, WASP-93b and WASP-118b: Three new transiting close-in giant planets
K. L. Hay, A. Collier-Cameron, A. P. Doyle +36
We present the discovery of three new transiting giant planets, first detected with the WASP telescopes, and establish their planetary nature with follow up spectroscopy and ground…
From dense hot Jupiter to low-density Neptune: The discovery of WASP-127b, WASP-136b and WASP-138b
K. W. F. Lam, F. Faedi, D. J. A. Brown +38
We report three newly discovered exoplanets from the SuperWASP survey. WASP-127b is a heavily inflated super-Neptune of mass 0.18 +/- 0.02 M_J and radius 1.37 +/- 0.04 R_J. This is…
WASP-South transiting exoplanets: WASP-130b, WASP-131b, WASP-132b, WASP-139b, WASP-140b, WASP-141b & WASP-142b
Coel Hellier, D. R. Anderson, A. Collier Cameron +16
We describe seven exoplanets transiting stars of brightness V = 10.1 to 12.4. WASP-130b is a "warm Jupiter" having an orbital period of 11.6 d around a metal-rich G6 star. Its mass…
WASP-157b, a Transiting Hot Jupiter Observed with K2
T. Močnik, D. R. Anderson, D. J. A. Brown +17
We announce the discovery of the transiting hot Jupiter WASP-157b in a 3.95-d orbit around a V = 12.9 G2 main-sequence star. This moderately inflated planet has a Saturn-like densi…
