Evolution of Protoplanetary Disks

Project Summary

Drs. Aki Roberge and Carol Grady are pursuing studies related to Theme 2 of the NASA GSFC Astrobiology Node, “From Molecular Cores to Planets: Our Interstellar Heritage.” Over the last year, they have been preparing for two Open Time Key Projects using the recently launched Herschel Space Observatory. Herschel is expected to spearhead the next big advances in our knowledge of planet formation, protoplanetary disk evolution, and debris disks. One project (GASPS) will illuminate the evolution of gas abundances and chemistry in protoplanetary disks over the planet-forming phase. The other (DUNES) will sensitively probe the Sun’s nearest neighbors for signs of extrasolar Kuiper Belts. Dr. Roberge has also been working on plans for future direct observations of potentially habitable terrestrial planets.
