A broadband thermal emission spectrum of the ultra-hot Jupiter WASP-18b

LP Coulombe, B Benneke, R Challener, AAA Piette… - Nature, 2023 - nature.com
Close-in giant exoplanets with temperatures greater than 2,000 K ('ultra-hot Jupiters') have
been the subject of extensive efforts to determine their atmospheric properties using thermal …

Five key exoplanet questions answered via the analysis of 25 hot-Jupiter atmospheres in eclipse

Q Changeat, B Edwards, AF Al-Refaie… - The Astrophysical …, 2022 - iopscience.iop.org
Population studies of exoplanets are key to unlocking their statistical properties. So far, the

Aerosols in exoplanet atmospheres

P Gao, HR Wakeford, SE Moran, V Parmentier - 2021 - Wiley Online Library
Observations of exoplanet atmospheres have shown that aerosols, like in the solar system,
are common across a variety of temperatures and planet types. The formation and …

The continuing search for evidence of tidal orbital decay of hot Jupiters

KC Patra, JN Winn, MJ Holman, M Gillon… - The Astronomical …, 2020 - iopscience.iop.org
Many of the known hot Jupiters are formally unstable to tidal orbital decay. The only hot
Jupiter for which orbital decay has been directly detected is WASP-12, for which transit …
