Upside down: GJ3090 b the first retrograde exoplanet around an M dwarf detected with NIRPS
Y. Carteret, V. Bourrier, L. Parc +57
The angle between stellar spin axis and planetary orbital plane can provide key insights into the formation and dynamical evolution of planetary systems. In particular, this measur…
POSTELLAR: Posterior Stellar Spectrum Sampling - An Alternative to Approximate Stellar Spectra for Exoplanetary Analysis
Dhvani Doshi, Nicolas B. Cowan, Yashar Hezaveh +2
We present a novel approach to perform posterior sampling of the underlying stellar spectrum in high-resolution spectroscopic observations. Our method, postellar, coherently combin…
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…
Atmospheric Reconnaissance of TRAPPIST-1 f with JWST NIRISS SOSS: No Evidence for the Transit Light Source Effect
Olivia Lim, René Doyon, Ryan J. MacDonald +25
In just over three years of operation, JWST has observed all seven planets of the TRAPPIST-1 system. The two innermost planets were found to have little to no atmosphere, barring t…
No Persistent Helium Absorption in LHS 1140 b: Four JWST/NIRISS SOSS Transits and Multi-epoch Stellar He I Variability
Amélie Gressier, Charles Cadieux, René Doyon +4
The search for atmospheres on temperate terrestrial planets is important for understanding how these objects form and evolve, and their potential habitability. Recent transit obser…
