Observations of the Spatial and Power Distributions of Io’s Hotspot-Sourced Heat Flux
JUNO’S MULTI-INSTRUMENT VIEW OF IO, EUROPA, AND GANYMEDE I POSTER
planetary sciences | 11 december 2024
Michael Sowell, David J. Stevenson
The Jovian moon Io is the most volcanically-active body in the Solar System, and these volcanic sources source over half of Io’s total heat flux. Rece...

FORMATION AND EVOLUTION OF TERRESTRIAL PLANETS: FROM DUST TO HABITABLE WORLDS POSTER
planetary sciences | 09 december 2024
Mira Menezes, David J. Stevenson
Earth's slow rotation period (24 hours) arose because of the tidal recession of the Moon.A more typical formation period for large bodies forming from...

The Fuzzy Cores of Jupiter and Saturn
AGU ADVANCES
04 april 2024
Ravit Helled, David J. Stevenson
New interior models of Jupiter and Saturn suggest that both planets have “fuzzy cores.” These cores should be viewed as central regions...

Evaluating the Conversion of CO to CH4 in the Jovian Circumplanetary Disk as a Source of Abundant Water Ice in Ganymede and Callisto
GEOLOGY AND GEOPHYSICS OF ACTIVE SATELLITES AND SMALL BODIES POSTER
planetary sciences | 13 december 2023
Teng Ee Yap, David J. Stevenson
Interior structure models of the Jovian moons Ganymede and Callisto suggest they are characterized by water ice-rock ratios around unity. This abundan...
