Global Chemical Transport on Hot Jupiters: Insights from 2D VULCAN photochemical model
Shang-Min Tsai, Vivien Parmentier, João M. Mendonça +7
The atmospheric dynamics of tidally-locked hot Jupiters is characterized by strong equatorial winds. Understanding the interaction between global circulation and chemistry is cruci…
Methane Throughout the Atmosphere of the Warm Exoplanet WASP-80b
Taylor J. Bell, Luis Welbanks, Everett Schlawin +12
The abundances of major carbon and oxygen bearing gases in the atmospheres of giant exoplanets provide insights into atmospheric chemistry and planet formation processes. Thermoche…
A Non-Detection of Iron in the First High-Resolution Emission Study of the Lava Planet 55 Cnc e
Kaitlin C. Rasmussen, Miles H. Currie, Celeste Hagee +17
Close-in lava planets represent an extreme example of terrestrial worlds, but their high temperatures may allow us to probe a diversity of crustal compositions. The brightest and m…
Transit Timing Variations in the three-planet system: TOI-270
Laurel Kaye, Shreyas Vissapragada, Maximilian N. Gunther +69
We present ground and space-based photometric observations of TOI-270 (L231-32), a system of three transiting planets consisting of one super-Earth and two sub-Neptunes discovered…
ATMOSPHERIX: II- Characterising exoplanet atmospheres through transmission spectroscopy with SPIRou
F. Debras, B. Klein, J. -F. Donati +26
In a companion paper, we introduced a publicly-available pipeline to characterise exoplanet atmospheres through high-resolution spectroscopy. In this paper, we use this pipeline to…
ATMOSPHERIX: I- An open source high resolution transmission spectroscopy pipeline for exoplanets atmospheres with SPIRou
B. Klein, F. Debras, J. -F. Donati +28
Atmospheric characterisation of exoplanets from the ground is an actively growing field of research. In this context we have created the ATMOSPHERIX consortium: a research project…
Another look at the dayside spectra of WASP-43b and HD 209458b: are there scattering clouds?
Jake Taylor, Vivien Parmentier
The search for clouds on the dayside of hot Jupiters has been disadvantaged due to hot Jupiters having a limited number of high quality space-based observations. To date, retrieval…
Modelling the effect of 3D temperature and chemistry on the cross-correlation signal of transiting ultra-hot Jupiters: A study of 5 chemical species on WASP-76b
Joost P. Wardenier, Vivien Parmentier, Michael R. Line +1
Ultra-hot Jupiters are perfect targets for transmission spectroscopy. However, their atmospheres feature strong spatial variations in temperature, chemistry, dynamics, cloud covera…
Awesome SOSS: Atmospheric Characterisation of WASP-96 b using the JWST Early Release Observations
Jake Taylor, Michael Radica, Luis Welbanks +13
The newly operational JWST offers the potential to study the atmospheres of distant worlds with precision that has not been achieved before. One of the first exoplanets observed by…
Photochemical hazes dramatically alter temperature structure and atmospheric circulation in 3D simulations of hot Jupiters
Maria E. Steinrueck, Tommi Koskinen, Panayotis Lavvas +5
Photochemical hazes are expected to form in hot Jupiter atmospheres and may explain the strong scattering slopes and muted spectral features observed in the transmission spectra of…
A reflective, metal-rich atmosphere for GJ 1214b from its JWST phase curve
Eliza M. -R. Kempton, Michael Zhang, Jacob L. Bean +30
There are no planets intermediate in size between Earth and Neptune in our Solar System, yet these objects are found around a substantial fraction of other stars. Population statis…
The Hazy and Metal-Rich Atmosphere of GJ 1214 b Constrained by Near and Mid-Infrared Transmission Spectroscopy
Peter Gao, Anjali A. A. Piette, Maria E. Steinrueck +12
The near-infrared transmission spectrum of the warm sub-Neptune exoplanet GJ 1214 b has been observed to be flat and featureless, implying a high metallicity atmosphere with abunda…
Hotter Than Expected: HST/WFC3 Phase-resolved Spectroscopy of a Rare Irradiated Brown Dwarf with Strong Internal Heat Flux
Rachael C. Amaro, Daniel Apai, Yifan Zhou +8
With infrared flux contrasts larger than typically seen in hot Jupiter, tidally-locked white dwarf-brown dwarf binaries offer a superior opportunity to investigate atmospheric proc…
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…
