eccentric planets

Transits: correlation planetary core mass
Guillot et al.
and stellar metallicity
•Transit observations & RV mass measurements show that the core mass
of giant planets, and the stellar metallicity are positively correlated.
•This is reproduced by core accretion models.
•Recent observations maybe even indicate that that all giant planets
contain at least 10 ME of metals.
•For direct collapse, planets can result both enriched and depleted.
