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...

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...

Monthly Notices of the Royal Astronomical Society, 473(1), 91-104. https://doi.org/10.1093/mnras/stx2401

We present a new analysis of the rapidly oscillating Ap (roAp) star, 2MASS J19400781 - 4420093 (J1940; V = 13.1). The star was discovered using SuperWASP broadband photometry to have a frequency of 176.39 d-1 (2041.55 µHz; P = 8.2 min; (Holdsworth et...

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.

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...

Monthly Notices of the Royal Astronomical Society, 471(3), 2743 - 2752. https://doi.org/10.1093/mnras/stx1729

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...

Monthly Notices of the Royal Astronomical Society, 467(2), 1714 - 1733. https://doi.org/10.1093/mnras/stx154

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...
