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…
Contamination from a nearby star cannot explain the anomalous transmission spectrum of the ultra-short period giant planet WASP-103b
John Southworth, Daniel F. Evans
The planet in the WASP-103 system is an excellent candidate for transmission spectroscopy because of its large radius and high temperature. Application of this technique found a va…
Qatar Exoplanet Survey : Qatar-3b, Qatar-4b and Qatar-5b
Khalid A. Alsubai, Dimitris Mislis, Zlatan I. Tsvetanov +12
We report the discovery of Qatar-3b, Qatar-4b, and Qatar-5b, three new transiting planets identified by the Qatar Exoplanet Survey (QES). The three planets belong to the hot Jupite…
Absolute parameters for AI Phoenicis using WASP photometry
J. A. Kirkby-Kent, P. F. L. Maxted, A. M. Serenelli +5
AI Phe is a double-lined, detached binary, in which a K-type sub-giant star totally eclipses its main-sequence companion every 24.6 days. This configuration makes AI Phe ideal for…
High-resolution Imaging of Transiting Extrasolar Planetary systems (HITEP). I. Lucky imaging observations of 101 systems in the southern hemisphere
D. F. Evans, J. Southworth, P. F. L. Maxted +33
(abridged) Context. Wide binaries are a potential pathway for the formation of hot Jupiters. The binary fraction among host stars is an important discriminator between competing fo…
