The Nucleosynthetic Fingerprint of the Outermost Protoplanetary Disk and Early Solar System Dynamics
Knowledge of the nucleosynthetic isotope composition of the outermost protoplanetary disk is critical to understand the formation and early dynamical evolution of the Solar System.

Two Studies Of Volatile Elements Discovered In Meteorites Constrain The Assembly Of Earth
In two separate studies, researchers identify nucleosynthetic isotope anomalies in the volatile elements potassium (K) and zinc (Zn) in meteorites, which constrain the origins of the material that formed Earth.
