The SPIRou Legacy Survey (SLS)

SPIRou is the new near-infrared (nIR) spectropolarimeter / velocimeter for the Canada-France-Hawaii Telescope (CFHT). SPIRou aims in particular at becoming world-leader on two forefront science topics, (i) the quest for Earth-like planets in the habitable zones of very-low-mass stars, and (ii) the study of low-mass star & planet formation in the presence of magnetic fields. The science programs that SPIRou proposes to tackle are forefront, ambitious and timely - ideally phased in particular with complementary space missions like TESS and JWST.

The amount of observing time required to complete the two main science goal of SPIRou is large. In this context, SPIRou only makes sense if coupled to a SPIRou Legacy Survey (SLS) of ~500 CFHT nights on a timescale of 5 yr starting after the commissioning of SPIRou, and focussed mostly on both main science goals. The SLS is divided into three main components, two of them dedicated to exoplanets around M dwarfs, and one focussed on large-scale magnetic felds & young hot Jupiters of pre-main-sequence (PMS) stars.

The observations comprising the SLS are in particular intended to achieve the following objectives: (i) accomplish selected large-scale community-defined scientific programs and (ii) provide the community with an extensive, homogenous, well characterized, and high quality database having the potential for a wide range of long-lasting scientific applications with a clear Legacy dimension.  This makes the SLS very similar in essence to its predecessor - the CFHTLS w/ MegaCam.

The science team in charge of the SLS is structured into a large community of registered users, whose task is divided into five main work packages (WPs), each split into a number of sub WPs. The goal of these WPs is to make sure that the science preparation of the SLS is well synchronized with the construction of the instrument, that the collected data are compliant in terms of quality and sampling once observations begin, and that the science return is maximized in all the research fields to which the SLS is expected to contribute.
