SUMMARY:Peering into the interiors of Earth-like planets - Tom Wilson (St 
 Andrews)

DESCRIPTION:The abundance of discovered planets has led to demographic stu
 dies that have revealed population-level trends in planetary properties th
 at are thought to be the imprints of planet formation or evolution. For ex
 ample\, in recent years we have started to discover trends in planetary bu
 lk density as a function of stellar metallicity for low-mass super-Earths 
 and sub-Neptunes\, thereby strongly hinting at a compositional link betwee
 n terrestrial planets and their stars. The feature-specific or population-
 synthesis based modelling used to explain observed demographics also provi
 de predictions of the nature of planets based on the underlying physical p
 rocesses. For example\, small planets (Rp < 4 R_Earth) might be classified
  as rocky\, water\, or gaseous based on their orbital or physical properti
 es. Such properties are often observable\, however the planets in previous
  large-scale studies often lack refined measurements precluding classifica
 tion of the bodies. Therefore\, we must follow-up these planets with speci
 alised instruments to characterise Earth-like planets and advance our unde
 rstanding of planet formation and evolution.\n\nIn this talk\, I will pres
 ent ongoing observational work with the CHEOPS spacecraft to measure the r
 adii of terrestrial planets in order to determine the internal composition
 al nature of these bodies and test demographic model predictions. Thus\, b
 y peering into the interiors of Earth-like planets we can learn about the 
 formation and evolution of planets across the Galaxy.\n
