Chondrites and the protoplanetary disk : November 8-11, 2004, Kaua'i, Hawai'i

Abstract

Attempts to understand how components in primitive chondrites and interplanetary dust particles were formed and thermally processed in the protoplanetary disk by comparing cosmochemical constraints with astronomical observations of young stellar objects, protostellar disks, and astrophysical models for thermal processing of dust by shock waves, disk winds, and asteroidal collisions. Reviews the major advances since the 1994 Conference on Chondrules and the Protoplanetary Disk in characterizing and understanding the isotopic, mineralogical, and chemical compositions of chondritic components in diverse kinds of primitive chondrites, constraining their ages and thermal histories, and developing models for their origin and accretion into chondritic planetesimals.
