Planets are expected to conclude their growth through a series of giant impacts: energetic, global events that significantly alter planetary composition and evolution.

Migration Processes In The Solar System And Their Role In The Evolution Of The Earth And Planets
We discuss problems of planetesimal migration in the emerging Solar System and exoplanetary systems. Protoplanetary disk evolution models and the formation of planets are considered.

Terrestrial Planet Formation From A Ring
It has been long proposed that, if all the terrestrial planets form within a tiny ring of solid material at around 1 AU, the concentrated mass-distance distribution of the current […]

Internal Or External Magma Oceans In The Earliest Protoplanets — Perspectives From Nitrogen And Carbon Fractionation
When the extent of protoplanetary melting approached magma ocean (MO)-like conditions, alloy melts efficiently segregated from the silicates to form metallic cores.

Linking The Evolution of Terrestrial Interiors And An Early Outgassed Atmosphere to Astrophysical Observations
A terrestrial planet is molten during formation and may remain so if subject to intense insolation or tidal forces. Observations continue to favour the detection and characterisation of hot planets, […]
