Our Research

We aim to discover and understand extrasolar planets, through pioneering detection studies, observations of their nebular birthplaces, modeling of their formation, and using the detection of small bodies in the outer Solar System to understand the origin of our own planetary system.

Tools of the Trade

We have access to Las Campanas Observatory in Chile, including the twin 6.5-m Magellan telescopes. EPL scientists design and develop advanced instrumentation for high-precision radial velocity measurements of distant stars and high-resolution infrared spectroscopic investigations of their compositions and that of their surrounding planetary disks.

Theoretical approaches utilize high-performance computing systems both on campus and the Caltech Resnick and Carnegie Memex2 clusters.
