Since the discovery of the first exoplanet just over twenty years ago, the study of exoplanets has grown explosively. By now, astronomers have discovered thousands of exoplanets, with an incredibly diverse array of properties. This growth will undoubtedly continue into the future, as new kinds of planets are being observed with increasingly advanced telescopes. Faculty in CIERA study exoplanets theoretically and build instruments to directly image them.

Research at CIERA

The groups of Professors Rasio and Lithwick carry out theoretical work and simulations to study the long-term dynamics of planetary systems. Both groups study the chaotic dynamics of multi-planet systems as they evolve. Professor Rasio’s group also studies planet-planet interactions, star-planet interactions and tidal disruptions, and planets in binary star systems.

Professor Ulmer’s group is developing new infrared camera technology to advance our understanding of planetary systems by directly imaging planets around other stars.

Professor Wang’s group works on developing and using new instrumentation (high contrast imaging, high resolution spectroscopy, optical interferometry) to study directly imaged planetary systems and measure properties such as mass, orbital configuration, composition, and spin.
