Title: The SPIRou Legacy Survey: Discovering and Exploring New Worlds with SPIRou

Presenter: Jean-Fran├žois Donati


With 300 CFHT nights allocated over the next 8 semesters (2019a to 2022b), the SPIRou Legacy Survey (SLS), gathering a consortium of over 140 scientists worldwide, aims at achieving a breakthrough on two forefront topics using SPIRou, the nIR spectropolarimeter / high-precision velocimeter recently installed at CFHT. The SLS first aims at detecting and characterizing planetary systems around nearby M dwarfs, focussing especially on Earth-like planets located in the habitable zones of their host stars as well as on transiting planet candidates identified through photometric surveys with facilities such as K2 or TESS. Investigating the early stages in the life of stars and their planets, and in particular the impact of magnetic fields on this genesis, is the other main objective of the SLS, which comes as a logical addition to the exploration of nearby planetary systems for understanding how worlds like (and unlike) our Solar System are born. In my talk i will outline the main discoveries expected from the SLS, detail its practical implementation and give an account of the first few observations collected so far.
