Reassessing Sub-Neptune Structure, Radii, and Thermal Evolution
The Astrophysical JournalWe present a novel python-based 1D sub-Neptune evolution model that emphasizes the thermal evolution and potential solidification of the rock/iron core and the structure of the radiative atmosphere. This model explores planetary structure from the molten

The Planetary Science JournalAt sufficiently high pressures (∼Mbar) and low temperatures (∼10 ^3 –10 ^4 K), hydrogen and helium become partly immiscible. Interpretations of Jupiter’s and Saturn’s magnetic fields favor the existence of a statically stable layer near the Mbar pressure

The Astrophysical JournalSuper-puffs are a class of low-mass, large-radius planets that have challenged planet formation and evolution models. Their high inferred H/He mass fractions, required to explain their physical sizes, would lead to rapid atmospheric escape, raising ...

STRUCTURE AND DYNAMICS OF PLANETARY MAGNETOSPHERES
, 2022 The interactions between the ambient plasmas and the objects of the Solar System result in variable exchanges both in time and space of mass, momentum and energy within different types of magnetospheres. The characterization of the sources, the general circulation and the losses of the magnetospheric plasmas as well as the identification of the ...
