Radial velocity detection of the TRAPPIST-1 planetary system with SPIRou and NIRPS
Alexandrine L'Heureux, René Doyon, Charles Cadieux, Pascal Petit et autres
The system is well known for its seven transiting Earth-sized exoplanets. It has been extensively studied and characterized, notably with transit timing variations (TTVs), to precisely measure the mass of the planets. Using near-infrared spectroscopic observations obtained as part of the SPIRou …
