TIC 168789840: A Sextuply Eclipsing Sextuple Star System (2021)
Journal Article

We report the discovery of a sextuply eclipsing sextuple star system from TESS data, TIC 168789840, also known as TYC 7037-89-1, the first known sextuple system consisting of three eclipsing binaries. The target was observed in Sectors 4 and 5 during... Read More about TIC 168789840: A Sextuply Eclipsing Sextuple Star System.

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...

A Discrete Set of Possible Transit Ephemerides for Two Long-period Gas Giants Orbiting HIP 41378 (2019)
Journal Article

In 2015, K2 observations of the bright (V = 8.9, K = 7.7) star HIP 41378 revealed a rich system of at least five transiting exoplanets, ranging in size from super-Earths to gas giants. The 2015 K2 observations only spanned 74.8 days, and the outer th... Read More about A Discrete Set of Possible Transit Ephemerides for Two Long-period Gas Giants Orbiting HIP 41378.

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...

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...

Orbital and physical parameters of eclipsing binaries from the ASAS catalogue - IX. Spotted pairs with red giants (2016)
Journal Article

We present spectroscopic and photometric solutions for three spotted systems with red giant components. Absolute physical and orbital parameters for these double-lined detached eclipsing binary stars are presented for the first time. These were deriv...

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...

STARSPOTS ON WASP-85 (2016)
Journal Article

By analyzing K2 short-cadence observations, we detect starspots on WASP-85A, the host star of the hot Jupiter WASP-85Ab. The detection of recurring starspot occultation events indicates that the planet's orbit is aligned with the star's rotational ax... Read More about STARSPOTS ON WASP-85.

FORS2 observes a multi-epoch transmission spectrum of the hot Saturn-mass exoplanet WASP-49b (2016)
Journal Article

Context. Transmission spectroscopy has proven to be a useful tool for the study of exoplanet atmospheres, because the absorption and scattering signatures of the atmosphere manifest themselves as variations in the planetary transit depth. Several pla... Read More about FORS2 observes a multi-epoch transmission spectrum of the hot Saturn-mass exoplanet WASP-49b.
