Magnitude of stable iron isotope fractionation limited by multiple stages of terrestrial core formation
Gabriel Nathan, Seth A. Jacobson
One proposed mechanism for generating iron isotopic differences between planetary mantles and chondrites is metal-silicate equilibration during terrestrial core formation. Prior st…
Lithium Enrichment in a Subgiant Star with a Brown Dwarf Companion: A Planetary Engulfment Candidate
Brooke Kotten, Melinda Soares-Furtado, Ricardo Yarza +11
Theoretical models predict that subgiants within a narrow mass regime can retain detectable lithium enrichment signatures from planetary engulfment. We test this prediction using T…
Direct contact binary planetesimal formation from gravitational collapse
Jackson T. Barnes, Stephen R. Schwartz, Seth A. Jacobson
Bilobate contact binaries comprise a significant fraction of the relict Kuiper Belt, which includes the exemplary contact binary (486958) Arrokoth. The surfaces of its lobes contai…
