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-…

Chemical Fingerprints of M Dwarfs: High-Resolution Spectroscopy on 31 M Dwarfs with SPIRou

Farbod Jahandar, René Doyon, Étienne Artigau +10

We extend the methodology introduced by Jahandar et al. (2024) to determine the effective temperature and chemical abundances of 31 slowly-rotating solar neighborhood M dwarfs (M1-…

The Roasting Marshmallows Program with IGRINS on Gemini South II -- WASP-121 b has super-stellar C/O and refractory-to-volatile ratios

Peter C. B. Smith, Jorge A. Sanchez, Michael R. Line +19

A primary goal of exoplanet science is to measure the atmospheric composition of gas giants in order to infer their formation and migration histories. Common diagnostics for planet…

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…

NIRPS first light and early science: breaking the 1 m/s RV precision barrier at infrared wavelengths

Étienne Artigau, François Bouchy, René Doyon +111

The Near-InfraRed Planet Searcher or NIRPS is a precision radial velocity spectrograph developed through collaborative efforts among laboratories in Switzerland, Canada, Brazil, Fr…

A sub-solar metallicity on the ultra-short period planet HIP 65Ab

Luc Bazinet, Stefan Pelletier, Björn Benneke +2

Studying and understanding the physical and chemical processes that govern hot Jupiters gives us insights on the formation of these giant planets. Having a constraint on the molecu…

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…
