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.
for a recent talk summarizing some of the group's research.
There is an opening for a postdoc or higher level position in instrumentation in the group. We are looking for someone to play a major role in our M dwarf radial velocity spectrograph project. Experience in optical and mechanical design, laser technology, fiber optics, instrument integration, or software is desirable. Contact Jacob for more information.
We have just published two papers with the results from an intensive study of the hot Jupiter WASP-43b using HST.
Paper 1 (Stevenson et al.) presents the first phase-resolved emission spectroscopy of an exoplanet. See the paper at Science Express
or a preprint here
. In particular, check out the movie
showing an animation of the emission spectra and brightness temperature maps as a function of phase.
Paper 2 (Kreidberg et al.) presents a precise determination of the water abundance in the planet's atmosphere. See the paper at ApJ Letters
or a preprint (with supplementary figures) here

Former undergrad Hannah Diamond-Lowe's paper, which shows that the atmosphere of HD209458b likely does not have a thermal inversion, is now available: arXiv:1409.5336
