SUMMARY:Not-so-noble gases\, key tracers of Earth’s habitability: what t
 heir behaviour in planetary interiors can tell us? - CHRYSTELE SANLOUP\, S
 orbonne University

DESCRIPTION:Most accreted xenon on Earth is missing from its atmosphere\, 
 relatively to lighter noble gases\, and half of the argon budget might be 
 missing too. These observations point to their early escape from the atmos
 phere\, or retention at depth. Although chemists have been exploring xenon
  reactivity since the 1970s\, recognition of its potential occurrence in p
 lanetary interiors is only just beginning. This talk will review the react
 ivity of heavy noble gases under the extreme pressures found in planetary 
 interiors\, how we can probe it\, and why this matters to understand plane
 tary processes leading to Earth’s habitability.
