LRG-BEASTS: Ground-based Detection of Sodium and a Steep Optical Slope in the Atmosphere of the Highly Inflated Hot-Saturn WASP-21b
L. Alderson, J. Kirk, M. López-Morales +7
We present the optical transmission spectrum of the highly inflated Saturn-mass exoplanet WASP-21b, using three transits obtained with the ACAM instrument on the William Herschel T…
Confirmation of WASP-107b's extended Helium atmosphere with Keck II/NIRSPEC
James Kirk, Munazza K. Alam, Mercedes Lopez-Morales +1
We present the detection of helium in the extended atmosphere of the sub-Saturn WASP-107b using high resolution () near-infrared spectra from Keck II/NIRSPEC. We f…
ACCESS: A Visual to Near-infrared Spectrum of the Hot Jupiter WASP-43b with Evidence of , but no evidence of Na or K
Ian C. Weaver, Mercedes López-Morales, Néstor Espinoza +11
We present a new ground-based visual transmission spectrum of the hot Jupiter WASP-43b, obtained as part of the ACCESS Survey. The spectrum was derived from four transits observed…
Exoplanet characterisation in the longest known resonant chain: the K2-138 system seen by HARPS
T. A. Lopez, S. C. C. Barros, A. Santerne +36
The detection of low-mass transiting exoplanets in multiple systems brings new constraints to planetary formation and evolution processes and challenges the current planet formatio…
LRG-BEASTS: transmission spectroscopy and retrieval analysis of the highly-inflated Saturn-mass planet WASP-39b
James Kirk, Mercedes Lopez-Morales, Peter J. Wheatley +5
We present a ground-based transmission spectrum and comprehensive retrieval analysis of the highly inflated Saturn-mass planet WASP-39b. We obtained low-resolution spectra ($R \app…
LRG-BEASTS III: Ground-based transmission spectrum of the gas giant orbiting the cool dwarf WASP-80
J. Kirk, P. J. Wheatley, T. Louden +4
We have performed ground-based transmission spectroscopy of the hot Jupiter orbiting the cool dwarf WASP-80 using the ACAM instrument on the William Herschel Telescope (WHT) as par…
