Kyu-Hyun Chae

Kyu-Hyun Chae is a Professor in the Department of Physics and Astronomy at Sejong University, South Korea. With a PhD from the University of Pittsburgh (1999) and postdoctoral experience at the University of Manchester (2000–2003), he has been a faculty member at Sejong University since 2003.

Research Interests: Chae specializes in gravity, astrophysics, and cosmology, focusing on gravitational anomalies in wide binary stars, external field effects in galaxies, and dark matter vs. modified gravity theories. His recent work uses Gaia data and Bayesian 3D modeling to test Newtonian and Milgromian gravity frameworks.

Publication Trends: His articles (2025–2019) span wide binary star dynamics, galaxy rotation curves, MOND validation, and gravitational lensing statistics. Methodologies include radial-velocity analysis, Monte Carlo simulations, and numerical solutions for gravitational effects.

Research Resources: Chae leads the Gravity Lab at Sejong University, teaching courses such as Galactic Astronomy and Stellar Mechanics. His work has attracted international attention, including coverage in 76 news outlets and mentions on Wikipedia and X (Twitter).
