Understanding the structures and dynamics of the core of a planet is essential to constructing a global geochemical and geodynamical model, and has implication on the planet's thermal, compositional and orbital evolution.

Remote sensing of planetary interiors from space and ground based observations is entering a new era with perspectives in constraining their core structures and dynamics. Meanwhile, increasingly accurate seismic data provide unprecedented images of the Earth's deep interior. Unraveling planetary cores' structures and dynamics requires a synergy between many fields of expertise, such as mineral physics, geochemistry, seismology, fluid mechanics or geomagnetism.

This session welcomes contributions from all the aforementioned disciplines following theoretical, numerical, observational or experimental approaches.
