Active Moons In Our Solar System And Beyond — Io, Europa, Enceladus, Triton, and Exomoons
The outgassing signatures of Io, Europa, Enceladus, Triton, and Io-like exomoons are the focus of this review chapter. The rocky volcanic world of Io is unique in our Solar System, […]

Analysis Of Io’s tidal Response As A Function Of The Properties Of The Partially Molten Layer
Io’s internal heat is generated by Jupiter-driven tidal dissipation and Laplace resonance. This energy partially melts the mantle, but the melt fraction, depth, and spatial distribution of dissipation remain poorly […]

Mars’ “Young” Volcanoes Were More Complex Than Scientists Once Thought
What appears to be a single volcanic eruption is often the result of complex processes operating deep beneath the surface, where magma moves, evolves, and changes over long periods of […]

Rock Vapour Is Opaque: Implications For Dynamics And Observations Of Lava Planets
Extreme instellation on lava planets causes the rocky surface to melt and vaporize. Because the rock vapour composition is intrinsically tied to the mantle, atmospheric characterization of lava planets can […]
