Title: Optical-nIR synergy between SPIRou and SOPHIE

Presenter: Melissa Hobson


As a high-precision nIR spectropolarimeter on a 3.6m telescope, SPIRou is the ideal instrument to search for exoplanets around M-dwarfs, and to further probe known planetary systems where the host stars' faintness in the visible may have rendered detection of additional exoplanets impossible. Since 2011, an M dwarf survey has been carried out with the SOPHIE spectrograph at the Observatoire de Haute Provence, which has detected several planets and also various activity-induced signals. Several SOPHIE targets are in the SLS, and we have submitted an open-time proposal on a further three targets. Likewise, SLS targets will be observed with SOPHIE, in order to have visible spectra, and improve the sampling. In this contribution, we describe the SOPHIE results for these stars, and what we can expect SPIRou data to provide: the refinement of planetary parameters, the detection of additional planets, the confirmation of the stellar origin of activity signals.
