Transmission spectroscopy of WASP-52 b with JWST NIRISS: Water and helium atmospheric absorption, alongside prominent star-spot crossings
Marylou Fournier-Tondreau, Yanbo Pan, Kim Morel +20
In the era of exoplanet studies with JWST, the transiting, hot gas giant WASP-52 b provides an excellent target for atmospheric characterization through transit spectroscopy. WASP-…
CRIRES+ and ESPRESSO reveal an atmosphere enriched in volatiles relative to refractories on the ultra-hot Jupiter WASP-121b
Stefan Pelletier, Björn Benneke, Yayaati Chachan +11
One of the outstanding goals of the planetary science community is to measure the present-day atmospheric composition of planets and link this back to formation. As giant planets a…
JWST/NIRISS reveals the water-rich "steam world" atmosphere of GJ 9827 d
Caroline Piaulet-Ghorayeb, Bjorn Benneke, Michael Radica +30
With sizable volatile envelopes but smaller radii than the solar system ice giants, sub-Neptunes have been revealed as one of the most common types of planet in the galaxy. While t…
Biases in Exoplanet Transmission Spectra Introduced by Limb Darkening Parametrization
Louis-Philippe Coulombe, Pierre-Alexis Roy, Björn Benneke
One of the main endeavors of the field of exoplanetary sciences is the characterization of exoplanet atmospheres on a population level. The current method of choice to accomplish t…
Promise and Peril: Stellar Contamination and Strict Limits on the Atmosphere Composition of TRAPPIST-1c from JWST NIRISS Transmission Spectra
Michael Radica, Caroline Piaulet-Ghorayeb, Jake Taylor +9
Attempts to probe the atmospheres of rocky planets around M dwarfs present both promise and peril. While their favorable planet-to-star radius ratios enable searches for even thin…
A Benchmark JWST Near-Infrared Spectrum for the Exoplanet WASP-39b
A. L. Carter, E. M. May, N. Espinoza +77
Observing exoplanets through transmission spectroscopy supplies detailed information on their atmospheric composition, physics, and chemistry. Prior to JWST, these observations wer…
Transmission Spectroscopy of the Habitable Zone Exoplanet LHS 1140 b with JWST/NIRISS
Charles Cadieux, René Doyon, Ryan J. MacDonald +20
LHS 1140 b is the second-closest temperate transiting planet to the Earth with an equilibrium temperature low enough to support surface liquid water. At 1.7300.025 R,…
JWST Reveals CH, CO, and HO in a Metal-rich Miscible Atmosphere on a Two-Earth-Radius Exoplanet
Björn Benneke, Pierre-Alexis Roy, Louis-Philippe Coulombe +28
Even though sub-Neptunes likely represent the most common outcome of planet formation, their natures remain poorly understood. In particular, planets near 1.5-2.5 often…
Muted Features in the JWST NIRISS Transmission Spectrum of Hot-Neptune LTT 9779 b
Michael Radica, Louis-Philippe Coulombe, Jake Taylor +13
The hot-Neptune desert is one of the most sparsely populated regions of the exoplanet parameter space, and atmosphere observations of its few residents can provide insights into ho…
Nightside clouds and disequilibrium chemistry on the hot Jupiter WASP-43b
Taylor J. Bell, Nicolas Crouzet, Patricio E. Cubillos +80
Hot Jupiters are among the best-studied exoplanets, but it is still poorly understood how their chemical composition and cloud properties vary with longitude. Theoretical models pr…
