Title: The Amakihi Community Survey: wide science from wide spectra
Presenter: Claire Moutou
Abstract:
This talk will present the science context and objectives of an ambitious, wide-spread community survey making use of Wenaokeao, the combination of ESPaDOnS and SPIRou.We have gathered all interested experts of the Canadian and French communities to provide for a comprehensive program with a strong legacy value, with the following scientific questions in mind: i) what is the composition of the nearest exoplanet population, and what are the main systems of interest for further characterization? ii) what are the main physical processes controlling the earliest stages of stellar and planetary formation? iii) what are the dynamics and chemistry of exoplanetary atmospheres? iv) what roles does the magnetic field play across the HR diagram? v) what is the impact of chemistry on the formation of the first population of stars and the evolution of long-period black-hole binaries?With a rich program encompassing several key topics in the vast study of galactic astronomy, we sought to take advantage of the unique opportunity that Wenaokeao will soon offer at CFHT. The scientific impact of such a combination of spectropolarimetry, velocimetry and high resolution spectroscopy in both the optical and nIR domains simultaneously is unique in the world and offers fascinating promises.

Hill Note: in order to expose all science topics in a correct level of details, we could use a long talk, ie, 30min, with several orators. Thanks!
