On spectroscopic phase-curve retrievals: H2 dissociation and thermal inversion in the atmosphere of the ultra-hot Jupiter WASP-103 b
Quentin Changeat
This work presents a re-analysis of the spectroscopic phase-curve observations of the ultra hot Jupiter WASP-103 b obtained by the Hubble Space Telescope (HST) and the Spitzer Tele…
Near-infrared transmission spectrum of TRAPPIST-1 h using Hubble WFC3 G141 observations
A. Gressier, M. Mori, Q. Changeat +4
The TRAPPIST-1 planetary system is favourable for transmission spectroscopy and offers the unique opportunity to study rocky planets with possibly non-primary envelopes. We present…
A comparison of chemical models of exoplanet atmospheres enabled by TauREx 3.1
Ahmed F. Al-Refaie, Quentin. Changeat, Olivia Venot +2
Thermochemical equilibrium is one of the most commonly used assumptions in current exoplanet retrievals. As the James Webb Space Telescope (JWST) and Ariel launch draw near, assess…
Alfnoor: assessing the information content of Ariel's low resolution spectra with planetary population studies
Lorenzo V. Mugnai, Ahmed Al-Refaie, Andrea Bocchieri +3
The ARIEL Space Telescope will provide a large and diverse sample of exoplanet spectra, performing spectroscopic observations of about 1000 exoplanets in the wavelength range $0.5…
Cross-sections for heavy atmospheres: HO continuum
Lara O. Anisman, Katy L. Chubb, Jonathan Elsey +5
Most of the exoplanets detected up to now transit in front of their host stars, allowing for the generation of transmission spectra; the study of exoplanet atmospheres relies heavi…
The transmission spectrum of WASP-17 b from the optical to the near-infrared wavelengths: combining STIS, WFC3 and IRAC datasets
Arianna Saba, Angelos Tsiaras, Mario Morvan +6
We present the transmission spectrum of the inflated hot-Jupiter WASP-17 b, observed with the STIS and WFC3 instruments aboard the Hubble Space Telescope, allowing for a continuous…
ARES V: No Evidence For Molecular Absorption in the HST WFC3 Spectrum of GJ 1132 b
Lorenzo V. Mugnai, Darius Modirrousta-Galian, Billy Edwards +25
We present a study on the spatially scanned spectroscopic observations of the transit of GJ 1132 b, a warm (500 K) Super-Earth (1.13 R) that was obtained with the G1…
Ariel: Enabling planetary science across light-years
Giovanna Tinetti, Paul Eccleston, Carole Haswell +313
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
Detectability of Rocky-Vapour Atmospheres on Super-Earths with Ariel
Yuichi Ito, Quentin Changeat, Billy Edwards +3
Ariel will mark the dawn of a new era as the first large-scale survey characterising exoplanetary atmospheres with science objectives to address fundamental questions about planeta…
An exploration of model degeneracies with a unified phase curve retrieval analysis: The light and dark sides of WASP-43 b
Quentin Changeat, Ahmed F. Al-Refaie, Billy Edwards +2
The analysis of exoplanetary atmospheres often relies upon the observation of transit or eclipse events. While very powerful, these snapshots provide mainly 1-dimensional informati…
The Hubble WFC3 Emission Spectrum of the Extremely-Hot Jupiter, KELT-9b
Quentin Changeat, Billy Edwards
Recent studies of ultra hot-Jupiters suggested that their atmospheres could have thermal inversions due to the presence of optical absorbers such as TiO, VO, FeH and other metal hy…
