Dr. Xian-Yu Wang (汪宪钰)

Dr. Xian-Yu Wang is a postdoctoral researcher in the Department of Astronomy at Indiana University. His research explores the architecture, formation, and dynamical evolution of exoplanetary systems through high-precision photometry, radial-velocity observations, Rossiter-McLaughlin measurements, transit timing variations, and population-level statistical analyses.

He studies a broad range of systems, including hot and warm Jupiters, sub-Saturns, brown dwarfs, and multi-planet systems, with a particular focus on spin-orbit alignment, orbital eccentricity, planetary multiplicity, and the role of stellar companions. By combining detailed characterization of individual systems with high-consistency samples and statistical studies, his work aims to uncover how planetary systems form, migrate, and evolve.
