Rationale: Extraterrestrial materials provide a growing array of constraints on the history of the solar system in all stages of its formation. Observations and models of our own and other protoplanetary disks provide a growing body of complementary evidence. This workshop will bring together an interdisciplinary and global group of (1) observers of extrasolar disks and planets, (2) experts in the physical modeling of disks in time and space, and (3) specialists in the physical, chemical and isotopic properties of meteorites, comet samples, and planetary materials.

This workshop directly preceeds the 73rd Annual Meeting of the Meteoritical Society, July 26-30, and a July 31 symposium on chondrules, both at the Park Central Hotel in Manhattan.
A users' group meeting for the Pencil code will be held July 26-30 2010, at the American Museum of Natural History. It will include the developers and users of the Pencil Code, a parallelized magnetohydrodyanic simulation code. Discussion will include astrophysics, algorithms and software engineering.
The Pencil Code is used to simulate stars, disks, the ISM, and solar physics. For registration and local matters, email Jason Maron (email) 212-496-3442. The leader of the Pencil collaboration is Axel Brandenburg (email).
