Trottier Postdoctoral Fellow, Université de Montréal
Daniel completed his PhD. at UC Santa Cruz, where he modeled the interior structures of giant planets to compare against observed giant exoplanets using Bayesian statistical analyses. His thesis work provided new constraints on what these planets are made of, how heat flows through them, and what processes might have created them. This is valuable in part because giant planets are records of conditions in the protoplanetary disks from which planets form. Importantly, these results also make testable predictions on the radii and atmospheric compositions of this type of planet.
At UdeM, Daniel continues and expands his work to lower mass planets like Neptunes and Saturns. These planets are more numerous but also more difficult to model, as they can lose significant portions of their mass under certain conditions. Applying statistical and physical models to the observed planets will allow for empirical constraints on these processes. He is also interested in how hydrogen and helium mix with heavier elements in the interiors of giant planets, such as what conditions could cause a planet’s core to dissolve and mix into its envelope. This will allow astronomers to better connect planetary atmospheric composition with formation processes. Finally, he provides theoretical and modelling support to exoplanet discovery efforts to better characterize and interpret newfound planets.
