These declines led...
Constraints on the composition and thermal structure of Ariel’s icy crust as inferred from its largest observed impact crater
Michael T. Bland, Chloe B. Beddingfield, Tom A. Nordheim, Donald A. Patthoff, Steven D. Vance
2023, Icarus (395)
The large graben-like troughs and smooth plains visible on the surface of Ariel are indicative of a period of high heat flow in the Uranian moon's past. High heat flows on icy moons like Ariel can also enable viscous flow that removes impact crater topography, a process called viscous relaxation. Here we use numerical modeling to...
