Detecting molecules in Ariel low resolution transmission spectra
Andrea Bocchieri, Lorenzo V. Mugnai, Enzo Pascale +2
The Ariel Space Mission aims to observe a diverse sample of exoplanet atmospheres across a wide wavelength range of 0.5 to 7.8 microns. The observations are organized into four Tie…
Spitzer thermal phase curve of WASP-121 b
Giuseppe Morello, Quentin Changeat, Achrène Dyrek +2
Aims. We analyse unpublished Spitzer observations of the thermal phase-curve of WASP-121 b, a benchmark ultra-hot Jupiter. Methods. We adopted the wavelet pixel-independent compone…
Characterising a World Within the Hot Neptune Desert: Transit Observations of LTT 9779 b with HST WFC3
Billy Edwards, Quentin Changeat, Angelos Tsiaras +27
We present an atmospheric analysis of LTT 9779 b, a rare planet situated in the hot Neptune desert, that has been observed with HST WFC3 G102 and G141. The combined transmission sp…
A re-analysis of equilibrium chemistry in five hot Jupiters
Emilie Panek, Jean-Philippe Beaulieu, Pierre Drossart +4
Studying chemistry and chemical composition is fundamental to go back to formation history of planetary systems. We propose here to have another look at five targets to better dete…
Retrieval study of cool, directly imaged exoplanet 51 Eri b
Niall Whiteford, Alistair Glasse, Katy L. Chubb +12
Retrieval methods are a powerful analysis technique for modelling exoplanetary atmospheres by estimating the bulk physical and chemical properties that combine in a forward model t…
Correcting Exoplanet Transmission Spectra for Stellar Activity with an Optimised Retrieval Framework
Alexandra Thompson, Alfredo Biagini, Gianluca Cracchiolo +7
The chromatic contamination that arises from photospheric heterogeneities e.g. spots and faculae on the host star presents a significant noise source for exoplanet transmission spe…
Oxygen depletion in giant planets with different formation histories
S. Fonte, D. Turrini, E. Pacetti +5
The atmospheric C/O ratio of exoplanets is widely used to constrain their formation. To guarantee that the C/O ratio provides robust information, we need to accurately quantify the…
A broadband thermal emission spectrum of the ultra-hot Jupiter WASP-18b
Louis-Philippe Coulombe, Björn Benneke, Ryan Challener +73
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…
YunMa: Enabling Spectral Retrievals of Exoplanetary Clouds
Sushuang Ma, Yuichi Ito, Ahmed Faris Al-Refaie +3
In this paper, we present YunMa, an exoplanet cloud simulation and retrieval package, which enables the study of cloud microphysics and radiative properties in exoplanetary atmosph…
