Title:
Is modeling the chemical evolution and differentiation of exoplanets a distant prospect or within our grasp?

Abstract:
The Earth evolved features like a core, mantle, crust and atmosphere by undergoing chemical differentiation. We can extrapolate that such a process may have formed other rocky bodies in our solar system and that exoplanets have done the same. On Earth, much of this chemical differentiation can be modeled for the history of the planet. Consequently, the chemistry of life is likely linked to the inorganic chemical evolution of the planet. Can the same be said for exoplanets with more diverse chemical variability than the objects of our solar system? How are geochemical models generalized to non-terrestrial environments? Do we have the experimental or observational data to differentiate different types of planetary evolution? Do we have the computational infrastructure to systematically generate, modify, maintain, and couple these models to one another? This seminar will address many of these questions and offer a perspective of where we are and where we are going in pursuit of
modeling an entire planet geochemically.
