2007 Annual Science Report

University of California, Los Angeles Reporting  |  JUL 2006 – JUN 2007

Executive Summary

In response to the new NASA budget we redistributed the resources of the UCLA lead
team of the NASA Astrobiology Institute (NAI). The result is a more focused research
program that emphasizes linking astronomical studies to the evolution of our own solar
system, studies of early Earth and the Earth-Moon system, and isotope ratios as
biosignatures. Our progress in these areas during the course of the past year is described
below.

Evolving planetary systems: Our work on characterizing young stellar systems has
progressed substantially this past year. UCLA NAI team members Edward Young and
Mark Morris and graduate student Rachel Smith collaborated with Caltech Hubble
Fellow Klaus Pontoppidan to obtain new measurements of the oxygen isotope ratios of
young stellar objects that emphasize the distinction between oxygen comprising the solar
system and normal oxygen in the galaxy (Smith et al., 2007).
