Rayleigh scattering in the transmission spectrum of HAT-P-18b
J. Kirk, P. J. Wheatley, T. Louden +5
We have performed ground-based transmission spectroscopy of the hot Jupiter HAT-P-18b using the ACAM instrument on the William Herschel Telescope (WHT). Differential spectroscopy o…
Transmission spectroscopy of the inflated exoplanet WASP-52b, and evidence for a bright region on the stellar surface
J. Kirk, P. J. Wheatley, T. Louden +5
We have measured the transmission spectrum of the extremely inflated hot Jupiter WASP-52b using simultaneous photometric observations in SDSS u', g' and a filter centred on the sod…
From dense hot Jupiter to low-density Neptune: The discovery of WASP-127b, WASP-136b and WASP-138b
K. W. F. Lam, F. Faedi, D. J. A. Brown +38
We report three newly discovered exoplanets from the SuperWASP survey. WASP-127b is a heavily inflated super-Neptune of mass 0.18 +/- 0.02 M_J and radius 1.37 +/- 0.04 R_J. This is…
Reconstructing the high energy irradiation of the evaporating hot Jupiter HD 209458b
Tom Louden, Peter J. Wheatley, Kevin Briggs
The atmosphere of the exoplanet HD 209458b is undergoing sustained mass loss, believed to be caused by X-ray and extreme-ultraviolet (XUV) irradiation from its star. The majority o…
K2-110 b - a massive mini-Neptune exoplanet
H. P. Osborn, A. Santerne, S. C. C. Barros +33
We report the discovery of the exoplanet K2-110 b (previously EPIC212521166b) from K2 photometry orbiting in a 13.8637d period around an old, metal-poor K3 dwarf star. With a V-ban…
Strong XUV irradiation of the Earth-sized exoplanets orbiting the ultracool dwarf TRAPPIST-1
Peter J. Wheatley, Tom Louden, Vincent Bourrier +2
We present an XMM-Newton X-ray observation of TRAPPIST-1, which is an ultracool dwarf star recently discovered to host three transiting and temperate Earth-sized planets. We find t…
