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.
Professor Geller studies how gravitational interactions within star clusters can modify planetary systems over time, using numerical simulations, and how these simulated planets correspond with observations.
Professor Lecoanet studies flows in stars, as well as tidal interactions between planets and stars.

Three Phases of the Eclipse
Three Phases of the Eclipse
The blood moon was visible during a total lunar eclipse, when Earth cast its shadow over the moon. This photo was taken by CIERA graduate student Imran Sultan, amateur astrophotographer and member of Professor Claude-André Faucher-Giguère‘s research group. Sultan photographed the entire event, which lasted about four hours early Friday morning (12-4am), using a refractor

2024 CIERA public lecture – “The Jazz of Physics” with Stephon Alexander
2024 CIERA public lecture – “The Jazz of Physics” with Stephon Alexander
On November 14, over 300 people packed Northwestern University’s Lutkin Hall to join Professor Stephon Alexander in a celebration of The Jazz of Physics for CIERA’s 15th anniversary public lecture. Over 100 others joined the livestream for an evening that began with a live jazz performance from the Star Eyes Initiative, followed by Prof. Alexander’s public lecture, and concluded with a

Tsuchinshan-ATLAS Comet
Tsuchinshan-ATLAS Comet
Just days after comet Tsuchinshan-Atlas (C/2023 A3) peaked at a brilliant +2 magnitude on October 12, 2024, the Lake Forest College Astronomy Club hosted a campus-wide viewing event led by senior Dean Kousiounelos in collaboration with the Physics department. During this time, the comet’s tail was visible with a good pair of binoculars, drawing in
