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…
