Talk Title: 
A Synthesized View of Planetary Systems
Event description: 

A tremendous diversity of exoplanets and protoplanetary disks has been discovered over the past three decades, offering an unprecedented lens into the range of formation pathways available for planetary systems. In parallel, studies of the solar system have revealed tantalizing, complementary constraints with exquisite detail. I will describe how, taken in conjunction, these two lines of evidence can be combined to advance our current understanding of planetary systems.

Drawing from the relationship between stars, planets, and neighboring minor planets, I will focus on the interface between subfields. I will discuss how minor planets, including interstellar objects and distant solar system bodies, provide evidence for hidden, wide-orbiting planetary perturbers in both the solar system and extrasolar systems. I will also describe a novel algorithm to directly search for the most distant solar system objects using the TESS dataset. Then, I will highlight how observational constraints on planetary system architectures and compositions provide complementary information regarding the key planet formation pathways. I will conclude with the prospects for future constraints on planetary system evolution using a combination of cutting-edge modern instruments such as EXPRES, KPF, PARVI, and TESS.
