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.


07/29/2016: A stabilized Fabry-Perot etalon for calibration of radial velocity spectrometers at the cm/s level: Stürmer et al. (ApJ submitted).

05/30/2016: Two new papers from our group this week:

Line et al. (ApJ submitted, see figure to the right) present a HST/WFC3 emission spectrum of HD209458b that definitively shows this planet does not have a thermal inversion.

Seifahrt et al. (SPIE submitted) report on the design and construction of MAROON-X.

05/24/2016: Congratulations to Dr. Laura Kreidberg for defending her dissertation!
