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.


09/10/2014: Group member Megan Bedell has written a paper about the acheivable precision for chemical abundance measurements in Solar Twins: arXiv:409.1230.

And, Paper I from the HARPS Solar Twin Planet Search, which presents the stellar parameters of the sample, is now available: arXiv:1408.4130.

06/29/2014: Two new papers from our group: arXiv:1406.7567 and arXiv:1406.5244

04/21/2014:Our new detector system for LDSS-3 achieved first light on the Magellan II telescope in March.
