Continued Studies of Stardust in IDPs

We recently reported the first identification of stardust in IDPs. Here we present the results of a detailed analysis of the original and subsequent O isotopic studies of anhydrous cluster IDPs. Anhydrous cluster IDPs were selected because they have preserved molecular cloud material, as evidenced by large enrichments in deuterium. Further, they have escaped aqueous and thermal processing, which could destroy or modify their mineralogy.
