The Planetary Chemistry Laboratory is run by Professor Bruce Fegley, Jr. and Dr. Katharina Lodders in the Department of Earth and Planetary Sciences at Washington University in St. Louis. We specialize in modeling gas chemistry in the atmospheres of the Earth, terrestrial planets and exoplanets, gas giants and their satellites, and cool stars. Have a look at our Research page to learn more about what we do.
All published peer-reviewed papers by Prof. Fegley and Dr. Lodders are available through the Publications page for your personal use. Posters, talks, and abstracts presented at conferences and meetings will be posted under Presentations (this site under construction).
News items about current research, published papers, and other goings-on in the Planetary Chemistry Laboratory are posted below.
Our site is currently under construction, so come back soon to see the improvements and updated content!

We have submitted a new paper to the Astrophysical Journal Letters. This paper is entitled ‘Atmospheric Chemistry of Venus-like Exoplanets’ by Laura Schaefer and Bruce Fegley. The paper applies models of atmosphere-lithosphere equilibrium developed for Venus to potential terrestrial-sized exoplanets. The paper makes predictions about the chemical composition of the atmospheres of Venus-like exoplanets, their surface pressures and temperatures, and the mineralogies of their surfaces. A preprint of the paper can be found here.
The magazine EARTH has an article about Prof. Fegley and Laura Schaefer’s work on the exoplanet CoRoT-7b in it’s January 2010 issue. The article is titled “Today’s Forecast: Quartz with a Chance of Feldspar” and is available both online and in the print issue.
Bruce Fegley and Laura Schaefer have co-written a chapter on the Earth’s earliest atmospheres with Kevin Zahnle of NASA Ames. The chapter will appear in a book about the origins of life edited by Dave Deamer and Jack Szostak. A preprint of the chapter is available here.
