High-precision multi-wavelength eclipse photometry of the ultra-hot gas giant exoplanet WASP-103 b (2017)
Journal Article

We present sixteen occultation and three transit light curves for the ultra-short period hot Jupiter WASP-103b, in addition to five new radial velocity measurements. We combine these observations with archival data and perform a global analysis of th...

The SuperWASP catalogue of 4963 RR Lyr stars: identification of 983 Blazhko effect candidates (2017)
Journal Article

Aims. We set out to compile a catalogue of RRab pulsating variables in the SuperWASP archive and identify candidate Blazhko effect objects within this catalogue. We analysed their light curves and power spectra for correlations in their common charac...

The EBLM Project: IV. Spectroscopic orbits of over 100 eclipsing M dwarfs masquerading as transiting hot Jupiters (2017)
Journal Article

We present 2271 radial velocity measurements taken on 118 single-line binary stars, taken over eight years with the CORALIE spectrograph. The binaries consist of F/G/K primaries and M dwarf secondaries. They were initially discovered photometrically... Read More about The EBLM Project: IV. Spectroscopic orbits of over 100 eclipsing M dwarfs masquerading as transiting hot Jupiters.

The EBLM project - III. A Saturn-size low-mass star at the hydrogen-burning limit (2017)
Journal Article

We report the discovery of an eclipsing binary system with mass-ratio q ~ 0.07. After identifying a periodic photometric signal received by WASP, we obtained CORALIE spectroscopic radial velocities and follow-up light curves with the Euler and TRAPPI...

Emission lines in the atmosphere of the irradiated brown dwarf WD0137-349B (2017)
Journal Article

We present new optical and near-infrared spectra of WD0137-349; a close white dwarf–brown dwarf non-interacting binary system with a period of ˜114 min. We have confirmed the presence of Ha emission and discovered He, Na, Mg, Si, K, Ca, Ti and Fe emi... Read More about Emission lines in the atmosphere of the irradiated brown dwarf WD0137-349B.

WASP-167b/KELT-13b: joint discovery of a hot Jupiter transiting a rapidly rotating F1V star (2017)
Journal Article

We report the joint WASP/KELT discovery of WASP-167b/KELT-13b, a transiting hot Jupiter with a 2.02-d orbit around a V = 10.5, F1V star with [Fe/H] = 0.1 ± 0.1. The 1.5 RJup planet was confirmed by Doppler tomography of the stellar line profiles duri...

Rotation of Planet-Hosting Stars (2017)
Book Chapter

The rotation rate of a star has important implications for the detectability, characterization, and stability of any planets that may be orbiting it. This chapter gives a brief overview of stellar rotation before describing the methods used to measur... Read More about Rotation of Planet-Hosting Stars.

The formation of EL CVn-type binaries (2017)
Journal Article

EL CVn-type binaries are eclipsing binaries that contain an A- or F-type dwarf star and a very low mass (~0.2?M?) helium white dwarf precursor (proto-He WD). A number of such objects have been discovered in the Wide Angle Search for Planets and Keple... Read More about The formation of EL CVn-type binaries.

The Surface Brightness-color Relations Based on Eclipsing Binary Stars: Toward Precision Better than 1% in Angular Diameter Predictions (2017)
Journal Article

In this study we investigate the calibration of surface brightness–color (SBC) relations based solely on eclipsing binary stars. We selected a sample of 35 detached eclipsing binaries with trigonometric parallaxes from Gaia DR1 or Hipparcos whose abs...

From Dense Hot Jupiter to Low Density Neptune: The Discovery of WASP-127b, WASP-136b and WASP-138b (2017)
Journal Article

We report three newly discovered exoplanets from the SuperWASP survey. WASP-127b is a heavily inflated super-Neptune of mass 0.18±0.02 MJ and radius 1.37±0.04 RJ. This is one of the least massive planets discovered by the WASP project. It orbits a br...

Peculiar architectures for the WASP-53 and WASP-81 planet-hosting systems (2017)
Journal Article

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 verified that the photometric signals were indeed produced by two tran...

Rossiter-McLaughlin models and their effect on estimates of stellar rotation, illustrated using six WASP systems (2017)
Journal Article

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 are new analyses of previously measured systems using new data (WASP-71,...
