We present the results of a systematic search of the Transiting Exoplanet Survey Satellite (TESS) 2-min cadence data for new rapidly oscillating Ap (roAp) stars observed during the Cycle 2 phase of its mission. We find seven new roAp stars previously... Read More about TESS Cycle 2 observations of roAp stars with 2-min cadence data.

Three Saturn-mass planets transiting F-type stars revealed with TESS and HARPS: TOI-615b, TOI-622b, and TOI-2641b (2023)
Journal Article

While the sample of confirmed exoplanets continues to grow, the population of transiting exoplanets around early-type stars is still limited. These planets allow us to investigate the planet properties and formation pathways over a wide range of stel...

Solar-to-supersolar sodium and oxygen absolute abundances for a ‘hot Saturn’ orbiting a metal-rich star. Monthly Notices of the Royal Astronomical Society, 515(2), 3037-3058. https://doi.org/10.1093/mnras/stac1530

We present new analysis of infrared transmission spectroscopy of the cloud-free hot-Saturn WASP-96b performed with the Hubble and Spitzer Space Telescopes (HST and Spitzer). The WASP-96b spectrum exhibits the absorption feature from water in excellen...

WASP-193b: An extremely low-density super-Neptune
Journal Article
Barkaoui, K., J. Pozuelos, F., Hellier, C., Smalley, B., D. Nielsen, L., Dorn, C., …G. West, R. WASP-193b: An extremely low-density super-Neptune. arXiv,

Gas giants transiting bright nearby stars are stepping stones for our understanding of planetary system formation and evolution mechanisms. This paper presents a particularly interesting new specimen of this kind of exoplanet discovered by the WASP-S... Read More about WASP-193b: An extremely low-density super-Neptune.
