Astrophysical Controls on the Elements of Life, Task 1: High-Precision Isotopic Studies of Meteorites
The initial Solar System abundances of the short-lived radionuclides (SLRs) 26Al (half life ~0.73 Ma) and 60Fe (half life ~2.6 Ma) are important to constrain since, if present in sufficient abundance, these SLRs served as heat sources for dehydration and differentiation processes on planetary bodies. The implications for this work include the astrophysical environment in which the Sun formed, and the abundance of water on the terrestrial planets.
