Exoplanet science with SPIRou: near-infrared precision velocimetry and spectropolarimetry.

High-precision radial-velocity measurements in the near-infrared allow one to search for exoplanet signals around the lowest-mass stars, including young ones. Because these stars can be among the most active ones, it is essential to characterize their magnetic activity. SPIRou, installed at the Canada--France--Hawai'i telescope, was designed to explore such planetary systems and characterize their properties. With a wide spectral range and large resolving power, SPIRou is also optimized for transmission spectroscopy and for investigating the chemical composition of exoplanetary atmospheres.
