Ice Giants Revisited: Uranus and Neptune as Magma Ocean Worlds
Edward D. Young, Sarah P. Marcum, Aaron Werlen +1
Uranus and Neptune are commonly interpreted as volatile-rich "ice giants", an assumption that underpins most interior models. Here we show that their observed radii, bulk densities…
A New Scaling Law for Non-Dipolar Magnetic Fields in Rapidly Rotating Stars and Planets
Paula N. Wulff, Hao Cao, Jonathan M. Aurnou
Magnetic field generation in giant planets and rapidly rotating stars produces a diverse range of field geometries, from large-scale dipole-dominated configurations to complex, sma…
On the meaning of the dynamo radius in giant planets with stable layers
Paula N. Wulff, Hao Cao, Jonathan M. Aurnou
Current structure models of Jupiter and Saturn suggest that helium becomes immiscible in hydrogen in the outer part of the planets' electrically conducting regions. This likely lea…
Lorentz force mediation of turbulent dynamo transitions
Krista M. Soderlund, Paula Wulff, Petri Käpylä +1
We investigate how the strength of the Lorentz force alters stellar convection zone dynamics in a suite of buoyancy-dominated, three-dimensional, spherical shell convective dynamo…
