Searching for Molecular Signatures in 14 Transiting Exoplanets with SPIRou
A. Masson, S. Vinatier, B. Bézard +6
High-resolution spectroscopy provides unique constraints on exoplanet atmospheric composition and dynamics. The past decade of ground-based campaigns has accumulated extensive publ…
Magnetic field strengths of hot giant exoplanets consistent with Solar System values
Julia V. Seidel, Vivien Parmentier, Bibiana Prinoth +29
Magnetic fields are ubiquitous in the universe. They play a key role in shaping the activity of stars, the habitability of rocky planets, and the long-term retention of planetary a…
A population view of transiting hot giant exoplanets: Tracing Fe and Ti chemistry with ESPRESSO and MAROON-X
Bibiana Prinoth, Vivien Parmentier, Stefan Pelletier +9
Hot and ultra-hot Jupiters offer a unique laboratory to study atmospheric chemistry at the population level using ground-based high-resolution spectroscopy. Fe and Ti are key trace…
Towards Doppler eclipse mapping of hot Jupiters. An observational perspective on WASP-33 b with SPIRou
Vincent Yariv, Xavier Bonfils, Nicolas Cowan +7
In the last decade, ground-based high-resolution spectroscopy (HRS) has emerged as a powerful method to probe exoplanet atmospheres both in transit and thermal emission. With HRS s…
Atmospheric characterization of HIP 67522 b with VLT/CRIRES+. VLT/CRIRES+ suggests a heavier planet and hints at deuterium fractionation
A. Lavail, F. Debras, B. Klein +9
Young transiting exoplanets provide unique opportunities to probe planetary atmospheres during the critical early phases of evolution. HIP 67522 b, a 17 Myr old hot Jupiter with an…
Characterizing planetary systems with SPIRou: questions about the magnetic cycle of 55 Cnc A and two new planets around B
C. Moutou, P. Petit, P. Charpentier +12
One of the first exoplanet hosts discovered thirty years ago, the star 55 Cnc has been constantly observed ever since. It is now known to host at least five planets with orbital pe…
