Alexander P. Stephan studies how stars, planets, and compact objects like white dwarfs and black holes interact and evolve together, especially in binary and triple-star systems. His work combines theoretical simulations with observational data to understand phenomena such as planets being swallowed by their stars, free-floating planets, and unusual exoplanet orbits. This research helps explain how planetary systems form, survive, and sometimes get destroyed as their host stars age.
Publication output has grown over the last decade, rising from occasional papers in 2017-2018 to a notable surge of activity in 2024 and 2026, though with some year-to-year variability.
