Exploring the Ability of HST WFC3 G141 to Uncover Trends in Populations of Exoplanet Atmospheres Through a Homogeneous Transmission Survey of 70 Gaseous Planets
Billy Edwards, Quentin Changeat, Angelos Tsiaras +14
We present the analysis of the atmospheres of 70 gaseous extrasolar planets via transit spectroscopy with Hubble's Wide Field Camera 3 (WFC3). For over half of these, we statistica…
Is binning always sinning? The impact of time-averaging for exoplanet phase curves
Giuseppe Morello, Achrène Dyrek, Quentin Changeat
We explore how finite integration time or temporal binning can affect the analysis of exoplanet phase-curves. We provide analytical formulae to account for this effect or, if negle…
Five key exoplanet questions answered via the analysis of 25 hot Jupiter atmospheres in eclipse
Quentin Changeat, Billy Edwards, Ahmed F. Al-Refaie +11
Population studies of exoplanets are key to unlocking their statistical properties. So far the inferred properties have been mostly limited to planetary, orbital and stellar parame…
A retrieval challenge exercise for the Ariel mission
Joanna K. Barstow, Quentin Changeat, Katy L. Chubb +5
The Ariel mission, due to launch in 2029, will obtain spectroscopic information for 1000 exoplanets, providing an unprecedented opportunity for comparative exoplanetology. Retrieva…
Cross-sections for heavy atmospheres: HO self-broadening
Lara O. Anisman, Katy L. Chubb, Quentin Changeat +4
The discovery of super-Earth and mini-Neptune exoplanets means that atmospheric signals from low-mass, temperate exoplanets are being increasingly studied. The signal acquired as t…
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…
