Astronomy Colloquium - "Planetary Systems in 4D"
Discoveries of exoplanets so different from those in our Solar System have called in question conventional theories for how planetary systems form and evolve. I will present recent progress in our understanding of the physical processes that drive the assembly of planetary systems and result in the surprising variety of orbital properties we observe today. In most of the talk, I will focus on the orbital evolution of giant planets, including the origin of hot Jupiters and giant planets on elliptical and tilted orbits. I will conclude with pathways forward toward establishing a new blueprint for how planetary systems form and evolve, including connections between small and giant planets and understanding the different initial conditions that lead to a diverse array of planetary systems.
