-====== The SLS main science goals ======
+====== Main science goals of the SLS, SPICE & PLANETS LPs ======
-The SLS concentrates on two main science goals. The first one is **to search for & characterize exo-Earths orbiting in the habitable zones (HZs) of low-mass & very-low mass stars** using high-precision radial velocity (RV) measurements (see left figure below). This search will expand the exploratory studies carried out with visible instruments (e.g., HARPS/ESO) and will focus in particular on planetary systems of nearby M dwarfs such as the 7-planet system discovered around Trappist-1, with special interest for planets located in the HZs of their host stars.  SPIRou will work in close collaboration with space- & ground-based photometric transit surveys like K2/NASA, TESS/NASA, CHEOPS/ESA, ExTrA and later-on PLATO/ESA to identify the true planets among the candidates they will discover.

-The second main goal is **to explore the impact of magnetic fields on star & planet formation**, by detecting fields of various types of young stellar objects (e.g. class-I, class-II and class-III pre-main-sequence / PMS stars, protostellar accretion discs) and by characterizing their large-scale topologies. SPIRou will also investigate the potential presence of giant planets around protostars and in the inner regions of accretion discs. In particular, this study will amplify the pioneering exploration surveys carried out at optical wavelengths within the MaPP (Magnetic Protostars and Planets) and [[https://matysse.irap.omp.eu|MaTYSSE]] (Magnetic Topologies of Young Stars and the Survival of close-in massive Exoplanets) CFHT Large Programs (LPs). It will also ideally complement results obtained with ALMA/ESO on planet-forming accretion discs (see right figure below) and dense prestellar cores.
