Zusammenfassung: | We address the issue of which broad set of initial conditions for the planet
Jupiter best matches the current presence of a ``fuzzy core" of heavy elements,
while at the same time comporting with measured parameters such as its
effective temperature, atmospheric helium abundance, radius, and atmospheric
metallicity. Our focus is on the class of fuzzy cores that can survive
convective mixing to the present day and on the unique challenges of an
inhomogeneous Jupiter with stably-stratified regions now demanded by the
\textit{Juno} gravity data. Hence, using the new code \texttt{APPLE}, we
attempt to put a non-adiabatic Jupiter into an evolutionary context. This
requires not only a mass density model, the major relevant byproduct of the
\textit{Juno} data, but a thermal model that is subject to interior heat
transport, a realistic atmospheric flux boundary, a helium rain algorithm, and
the latest equation of state. The result is a good fit to most major thermal,
compositional, and structural constraints that still preserve a fuzzy core and
that should inform future more detailed models of the current Jupiter in the
context of its evolution from birth. |
