WALTzER: Wide-band Atmospheric Laboratory for Transiting Exoplanet Research
A. G. Sreejith, L. Fossati, M. Lendl +81
Understanding the origin and evolution of planetary atmospheres, and the connection between their lower and upper atmospheric layers, remains a fundamental challenge in exoplanet s…
Stellar flares with Ariel: detection prospects and impacts on exoplanet spectroscopy
K. Vida, B. Seli, B. Edwards
Stellar flares are important tracers of magnetic activity and can significantly influence the characterization of exoplanet host stars by introducing time-dependent astrophysical v…
A JWST Transit of a Jupiter Analog: II. A Search for Exomoons
David Kipping, Ben Cassese, Quentin Changeat +3
We present a search for exomoons around the Jupiter-like exoplanet Kepler-167e using a NIRSpec JWST transit. Our 60 hour time series clearly reveals the enormous impact of long-ter…
A JWST Transit of a Jupiter Analog I: Constraints on the Oblateness of Kepler-167e
Ben Cassese, David Kipping, Quentin Changeat +5
In October 2024 JWST observed a transit of Kepler-167e, a Jupiter-analog planet on a 1000+ day orbit. These observations, recorded over a long baseline of nearly 60 hours, were des…
Measuring Tracers of Planet Formation in the Atmosphere of WASP-77A b: Sub-stellar O/H and C/H ratios, with a stellar C/O ratio and a potentially Super-stellar Ti/H ratio
Billy Edwards, Quentin Changeat
We present a comprehensive atmospheric retrieval study of the hot Jupiter WASP-77A\,b using eclipse observations from the Hubble Space Telescope (HST) and JWST. Using atmospheric r…
Is the atmosphere of the ultra-hot Jupiter WASP-121b variable?
Quentin Changeat, Jack W. Skinner, James Y-K. Cho +12
We present a comprehensive analysis of the Hubble Space Telescope observations of the atmosphere of WASP-121 b, a ultra-hot Jupiter. After reducing the transit, eclipse, and phase-…
