During the academic year, the Department hosts a weekly colloquium series which features speakers from both academia and industry. This semester (Spring 2021) the colloquia take place on Thursdays from 3:05-4:20 pm on Zoom. There will be no colloquia during the first and last weeks of the semester or during Spring Break. Please contact the colloquium coordinator, Paul Nerenberg (pnerenb [at] calstatela [dot] edu), for the link.

"Planet Formation from a Dynamical Perspective: Using Theoretical
Methods to Constrain and Understand the Outcomes of Planet Formation"
Feb. 25, 3:05 pm
Recent observational advances have allowed the discovery of thousands of exoplanets and an initial characterization of their orbital and physical parameters. As this population has grown, it is increasingly apparent that existing models of planet formation are incomplete. The Kepler/K2/TESS data have presented counterexamples to prevailing theories, including theories of how hot Jupiters form and how planets obtain their orbital inclinations. Similar developments have occurred in the solar system, where recent discoveries of the most distant solar system objects have required new explanations.
In this talk, I will present my work towards integrating the theory and the observational data. Resolving these conflicts requires a deep understanding of the current dynamical state and histories of benchmark systems beyond what the data alone can provide, and I explain how dynamics (analytic models and numerical simulations) can help give needed constraints. I will describe several recent exciting discoveries and my subsequent dynamical analyses, which have provided boundary conditions for our understanding of planet formation.
