L. Holdsworth, D., W. Kurtz, D., Smalley, B., Saio, H., Handler, G., J. Murphy, S., & Lehmann, H. HD 24355 observed by the Kepler K2 mission: A rapidly oscillating Ap star pulsating in a distorted quadrupole mode. https://doi.org/10.1093/mnras/stw1711. Manuscript submitted for publication

We present an analysis of the first Kepler K2 mission observations of a rapidly oscillating Ap (roAp) star, HD 24355 ($V=9.65$). The star was discovered in SuperWASP broadband photometry with a frequency of 224.31 d$^{-1}$, (2596.18 $\mu$Hz; $P = 6.4...

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...

Aims. We searched the SuperWASP archive for objects that display multiply periodic photometric variations. Methods. Specifically we sought evidence for eclipsing binary stars that display a further non-harmonically related signal in their power sp...

We have analysed around 170 000 individual photometric WASP (Wide Angle Search for Planets) measurements of 15 well-established ? Bootis stars to search for variability. The ? Bootis stars are a small group of late-B to early-F, Pop I, stars that sho... Read More about λ Bootis stars in the SuperWASP survey.

The Kepler space mission provided near-continuous and high-precision photometry of about 207 000 stars, which can be used for asteroseismology. However, for successful seismic modeling it is equally important to have accurate stellar physical paramet... Read More about Spectroscopic survey of Kepler stars.(a similar to...) I.

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

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.

WASP-20b and WASP-28b: a hot Saturn and a hot Jupiter in near-aligned orbits around solar-type stars (2015)

We report the discovery of the planets WASP-20b and WASP-28b along with measurements of their sky-projected orbital obliquities. WASP-20b is an inflated, Saturn-mass planet (0.31?MJup; 1.46?RJup) in a 4.9-day, near-aligned (? = 12.7 ± 4.2°) orbit aro...

We investigate the light variations of 15 Am stars using four years of high-precision photometry from the Kepler spacecraft and an additional 14 Am stars from the K2 Campaign 0 field. We find that most of the Am stars in the Kepler field have light c... Read More about Spots on Am stars.

We report the sky-projected orbital obliquity (spin–orbit angle) of WASP-84 b, a 0.69${{M}_{{\rm Jup}}}$ planet in an 8.52 day orbit around a G9V/K0V star, to be ? = -0.3 ± 1.7°. We obtain a true obliquity of ? = 17.3 ± 7.7° from a measurement of the... Read More about The well-aligned orbit of Wasp-84b: evidence for disk migration of a hot Jupiter.
