SUMMARY:Miscibility in sub-Neptunes - James Rogers / IoA

DESCRIPTION:Sub-Neptunes are found around 50% of Sun-like stars in our gal
 axy. Despite their ubiquity\, we lack a comprehensive understanding of the
 ir interior structure. I will present the first evolving interior structur
 e model for sub-Neptunes that accounts for the expected miscibility betwee
 n silicate magma and hydrogen. I will discuss the concept of "binodal surf
 aces"\, which represent phase transitions within sub-Neptunes and provide 
 a physically/chemically informed boundary between a planet’s "interior"'
  and "envelope". I will discuss the many implications of miscibility\, and
  a potential observational route to testing its prevalence.
