What is recorded here?
Wahl and colleagues compared numerical interior structure models against Jupiter’s even gravitational moments from Juno’s first two close orbits. In their model families an extended heavy-element-enriched core, mixed with hydrogen and helium, can improve agreement with the measurements; the authors explored how equations of state and envelope composition change the inferred core and gravitational moments.

Scientific scope
This is a model-based interpretation of existing Juno measurements, not direct imaging of a core or proof that it must be dilute. The paper finds compact-core solutions with a different equation of state or perturbed model; the tested reference model remains discrepant, and matching the gravity data can require changes to outer-envelope density or composition. Dynamic wind contributions increase the effective uncertainty. The abstract reports 7–25 Earth masses of heavy elements in the core while the body describes an approximate 6–25 bracket, so no sharper universal interval is claimed. Hydrogen-helium equation of state, assumed equilibrium, temperature/composition profiles and core erosion history are material limitations. Distinct later 2018 deep-jet inversion and 2021 vortex depth papers remain unverified HOLDs, not resolved by this source.
