主讲人/Speaker:

Prof. Lee Man Hoi is an Associate Professor at the University of Hong Kong working on the formation and dynamics of planetary and satellite systems. Prof. Lee received his BSc degree from the University of Toronto and PhD degree from Princeton University. He was a postdoctoral fellow and research scientist at the Canadian Institute for Theoretical Astrophysics, Queen’s University, and the University of California at Santa Barbara, before he joined the University of Hong Kong. He is best-known for his work on the 2:1 orbital resonance of the GJ 876 planets, the first resonant pair discovered among extrasolar planetary systems. The analysis of extrasolar planets in resonant pairs, near-resonance pairs and resonant chains has remained a major focus of his research. Another theme in his research in recent years are planetary bodies in and around binary systems. Prof. Lee is also known for his work on numerical methods. The symplectic integrator SyMBA has been a workhorse in numerical dynamical simulations for over 20 years. It has recently been efficiently parallelized and used to study giant planet formation in our solar system.

摘要/Abstract:

Observations of extrasolar planets have discovered pairs of planets in or near mean-motion resonances and resonant chains of three or more planets. I will discuss the dynamics of these systems and the constraints that they provide on the formation and dynamical evolution of planets. Topics will include high-order mean-motion resonances in the HD 202206 and n Ophiuchi systems and the formation of resonant chains near the inner edge of protoplanetary disks.
