Professor Dong Lai
Extrasolar planetary systems, protoplanetary disks, star and planet formation
I am a third-year graduate student working with Professor Dong Lai on the dynamics of exoplanetary systems. Currently, I am investigating the orbital evolution and migration of giant planets in systems with distant stellar companions. In this scenario, the companion star can perturb the planet into an extremely high-eccentricity orbit, with subsequent orbital decay due to tidal dissipation. Such systems can result in extremely close-in planets (“hot Jupiters”) with final orbital periods of several days or less. Through a combination of numerical simulations and semi-analytic work, our goal is to better understand the diversity of observed exoplanetary systems, and help constrain the formation mechanisms of hot Jupiters.
I received my B.S. in Physics from the University of Michigan (UM) in 2012, where I worked with Professor Fred Adams on exoplanet dynamics. After graduating, I continued my research at UM for a year, where I worked with Profs. Fred Adams, Nuria Calvet, and Anthony Bloch on several projects, including the dynamics of planets around post-main-sequence stars, and protoplanetary disk evolution.
