SPIRou near-infrared spectropolarimetry of the ultra-hot Jupiter KELT-9b: tentative detection of the planet magnetic field
Alexis Lavail, Florian Debras, David Rogé Royo +23
Exoplanetary magnetic fields govern atmospheric escape and circulation but have eluded detection in close-in planets. In the ultra-hot Jupiter KELT-9b, atmospheric dynamo is predic…
Probing Exoplanetary Chemistry with Ariel: Scientific Priorities and Observational Strategies
Olivia Venot, Yamila Miguel, Robin Baeyens +30
Over the past two decades, increasingly precise observations have revealed that exoplanet atmospheres are chemically diverse and often far from equilibrium, with processes such as…
Elemental Abundances of Cool Stars: A Spectroscopic Framework Applied to Five Planet-Host Stars
Nicole Gromek, Drew Weisserman, Ryan Cloutier +2
Stellar elemental abundances provide important constraints on the chemical environments from which planets form. M and late-K dwarfs are prime targets for the characterization of s…
Night-sky emission correction techniques for high-resolution spectroscopy: Demonstration with NIRPS
Avidaan Srivastava, François Bouchy, Xavier Dumusque +54
Ground-based spectrographs operating in the near-infrared (NIR) regime are hampered by various absorption and emission features of Earth's atmosphere. While considerable attention…
Radial velocity detection of the TRAPPIST-1 planetary system with SPIRou and NIRPS
Alexandrine L'Heureux, René Doyon, Charles Cadieux +57
The TRAPPIST-1 system is well-known for its seven transiting Earth-sized exoplanets. It has been extensively studied and characterized, notably with transit timing variations (TTVs…
EncoTESS: Age-Sensitive Encodings from Raw TESS Light Curves
Phil R. Van-Lane, Joshua S. Speagle, Ryan Cloutier +3
Main sequence stars of spectral types late F through M exhibit systematic variability in photometric light curves, particularly when they are young. Rotational modulation of starsp…
