November NSA Meeting

  • Arlington Heights Memorial Library 500 North Dunton Avenue Arlington Heights, IL, 60004 United States (map)

Arlington Heights native son Professor Daniel Fabrycky joins us from the University of Chicago for a program on the dynamics of extra-solar planets. The space within about one astronomical unit of other stars in the Galaxy is an exciting place to be a planet. The categories of "hot Jupiters", "super-Earths", "sub-Neptunes", and recent terrestrial analogues have been revealed by Doppler programs and space-based transit missions. Professor Fabrycky will detail how dynamical modeling of the data teaches us the properties of these planets and their orbital architectures. He'll also discuss the current theories of the formation and evolution of these systems.
