    First Steps of Planet Formation in Protoplanetary Disks

    Presenter: Elise Furlan ()

    October 15, 2007 11:00 AM Pacific

    Young stars are surrounded by circumstellar disks for several million years; it is in these disks that planets are thought to form. The Spitzer Space Telescope has been providing a wealth of data that aids in understanding the evolution of protoplanetary disks. I will present results from Spitzer that reveal significant disk evolution, ranging from dust grain growth to disk clearing, already at an age of 1 million years. Thus, we are observing the first steps of planet formation in several of these young disks, which place constraints on planet formation mechanisms.

The Director’s Seminar series features talks from scientists who are invited by the NAI Director to present their research results to the community. A primary goal of the seminars is to encourage interdisciplinary collaboration across NAI teams and within the astrobiology community at large.

Team Overview Seminars describe the work of the fourteen NAI teams and NAI Central. They offer an opportunity to find out more about the science, E/PO and other activities being performed by the NAI teams and the NAI Central office.

The Forum for Astrobiology Research (FAR) provides an opportunity for graduate students to present their research results and to meet as a student community for networking and mutual support.

The University of Washington seminar series is hosted by the NAI Virtual Planetary Lab (VPL) team from the UW campus in Seattle.
