This is the website for Prof. Jacob Bean's group in the Department of Astronomy & Astrophysics at the University of Chicago. The main theme of the group's research is the observational study of planets outside the Solar System ("exoplanets"). We use ground- and space-based telescopes to detect and characterize these worlds. We are also engaged in building new instruments as part of our push towards eventually identifying other Earth-like planets.

See here for a recent talk summarizing some of the group's research.


05/23/2018: See our latest SPIE conference proceeding for an update on MAROON-X. We remain on track to commission the instrument on Gemini-N in the first quarter of 2019.

05/23/2018: With our collaborators we have recently published four papers exploring the extreme physics and chemistry of ultra-hot Jupiters. See:

Arcangeli et al., ApJL, 855, 30 (WASP-18b dayside spectrum)
Kreidberg et al., AJ in press (WASP-103b phase-resolved spectroscopy)
Mansfield et al., AJ in press (HAT-P-7b dayside spectrum)
Parmentier et al., A&A in press (Synthesis of the theory of ultra-hot planets)

01/04/2018: MAROON-X is highlighed in the January 2018 issue of the Gemini Focus magazine.
