Discovery of Three New Transiting Hot Jupiters: WASP-161 b, WASP-163 b, and WASP-170 b (2019)
Journal Article

We present the discovery of three new transiting hot Jupiters by the WASP-South project, WASP-161 b, WASP-163 b, and WASP-170 b. Follow-up radial velocities obtained with the Euler/CORALIE spectrograph and transit light curves obtained with the TRAPP...

Machine-learning Approaches to Exoplanet Transit Detection and Candidate Validation in Wide-field Ground-based Surveys (2018)
Journal Article

Since the start of the Wide Angle Search for Planets (WASP) program, more than 160 transiting exoplanets have been discovered in the WASP data. In the past, possible transit-like events identified by the WASP pipeline have been vetted by human inspec...

Spectroscopic survey of Kepler stars - II. FIES/NOT observations of A- and F-type stars (2017)
Journal Article

We have analysed high-resolution spectra of 28 A and 22 F stars in the Kepler field, observed using the Fibre-Fed Échelle Spectrograph at the Nordic Optical Telescope. We provide spectral types, atmospheric parameters and chemical abundances for 50 s... Read More about Spectroscopic survey of Kepler stars - II. FIES/NOT observations of A- and F-type stars.

Eclipsing binary stars with a delta Scuti component (2017)
Journal Article

Eclipsing binaries with a d Sct component are powerful tools to derive the fundamental parameters and probe the internal structure of stars. In this study, spectral analysis of six primary d Sct components in eclipsing binaries has been performed. Va... Read More about Eclipsing binary stars with a delta Scuti component.

The Homogeneous Study of Transiting Systems (HoSTS) – II. The influence of the line list on stellar parameters (2017)
Journal Article

The use of high-resolution, high signal-to-noise stellar spectra is essential in order to determine the most accurate and precise stellar atmospheric parameters via spectroscopy. This is particularly important for determining the fundamental paramete... Read More about The Homogeneous Study of Transiting Systems (HoSTS) – II. The influence of the line list on stellar parameters.

Three new pulsating sdB stars discovered with SuperWASP (2017)
Journal Article

We present an analysis of three new pulsating subdwarf B stars discovered in the Super Wide Angle Search for Planets archive. Two of the stars, J1938+5609 and J0902-0720, are p-mode pulsators; J1938+5609 shows a pulsation at 231.62 d-1 (P = 373 s; 26...

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,...

Pulsation versus metallicism in Am stars as revealed by LAMOST and WASP (2016)
Journal Article

We present the results of a study of a large sample of A and Am stars with spectral types from LAMOST and light curves from WASP. We find that, unlike normal A stars, d Sct pulsations in Am stars are mostly confined to the effective temperature range...

Detection of Solar-Like Oscillations, Observational Constraints, and Stellar Models for theta Cyg, the Brightest Star Observed by the Kepler Mission (2016)
Journal Article

? Cygni is an F3 spectral type magnitude V = 4.48 main-sequence star that was the brightest star observed by the original Kepler spacecraft mission. Short-cadence (58.8 s) photometric data using a custom aperture were first obtained during Quarter 6...

Discovery of WASP-113b and WASP-114b, two inflated hot-Jupiters with contrasting densities (2016)
Journal Article

Aims. We present the discovery and characterisation of the exoplanets WASP-113b and WASP-114b by the WASP surveys, SOPHIE and CORALIE. Methods. The planetary nature of the systems was established by performing follow-up photometric and spectroscop...
