From Molecular Clouds to Habitable Planetary Systems
Co-I Weinberger pursued studies of young stars to assess the number with circumstellar disks as a function of age and to measure detailed properties of extant disks. Using the Keck Observatory, she searched for disks around stars of age 10 to 100 Million years (Myr) using sensitive 12- and 18-µm photometry.

EVOLUTION OF a HABITABLE PLANET: Planetary Habitability and Life Detection
In early July, 2003, a Science paper I was lead author on came out providing strong evidence for an old (~ 12 Gyr) jovian planet in a metal-poor, distant stellar system.

Delivery of Organic Materials to Planets
Kress and Brownlee, in collaboration with George Cody, have investigated the thermal alteration of organic material entering the atmosphere in small extraterrestrial particles. An interesting aspect of this process is that even the most severely heated particles eject sublimed compounds that survive.
