TIC 278825952: a triply eclipsing hierarchical triple system with the most intrinsically circular outer orbit (2020)
Journal Article

We report the discovery of a compact triply eclipsing triple star system in the southern continuous viewing zone of the TESS space telescope. TIC 278825952 is a previously unstudied, circular eclipsing binary with a period of 4.781 days with a tertia...

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...

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...

ELLC - a fast, flexible light curve model for detached eclipsing binary stars and transiting exoplanets (2016)
Journal Article

Very high quality light curves are now available for thousands of detached eclipsing binary stars and transiting exoplanet systems as a result of surveys for transiting exoplanets and other large-scale photometric surveys. I have developed a binary s... Read More about ELLC - a fast, flexible light curve model for detached eclipsing binary stars and transiting exoplanets.

WASP-121 b: a hot Jupiter close to tidal disruption transiting an active F star (2016)
Journal Article

We present the discovery by the WASP-South survey of WASP-121 b, a new remarkable short-period transiting hot Jupiter. The planet has a mass of 1.183+0.064-0.062MJup, a radius of 1.865 ± 0.044 RJup, and transits every 1.2749255+0.0000020-0.0000025 da...

The EChO science case (2015)
Journal Article

The discovery of almost two thousand exoplanets has revealed an unexpectedly diverse planet population. We see gas giants in few-day orbits, whole multi-planet systems within the orbit of Mercury, and new populations of planets with masses between th... Read More about The EChO science case.

The Araucaria project. Precise physical parameters of the eclipsing binary IO Aquarii (2015)
Journal Article

Aims. Our aim is to precisely measure the physical parameters of the eclipsing binary IO Aqr and derive a distance to this system by applying a surface brightness – colour relation. Our motivation is to combine these parameters with future precise di... Read More about The Araucaria project. Precise physical parameters of the eclipsing binary IO Aquarii.

WASP-80b has a dayside within the T-dwarf range (2015)
Journal Article

WASP-80b is a missing link in the study of exoatmospheres. It falls between the warm Neptunes and the hot Jupiters and is amenable for characterization, thanks to its host star's properties. We observed the planet through transit and during occultati... Read More about WASP-80b has a dayside within the T-dwarf range.
