Impact-induced differentiation in icy bodies
W. Brian Tonks, Elisabetta Pierazzo, H. Jay Melosh
By the time icy objects grow to about the mass of Europa and silicate bodies grow to approximately lunar mass, a large high-speed impact can generate an intact melt region that all…
Impact-induced melting during accretion of the Earth
Jellie de Vries, Francis Nimmo, H. Jay Melosh +3
Because of the high energies involved, giant impacts that occur during planetary accretion cause large degrees of melting. The depth of melting in the target body after each collis…
Rotationally Induced Surface Slope-Instabilities and the Activation of CO2 Activity on Comet 103P/Hartley 2
Jordan K. Steckloff, Kevin Graves, Toshi Hirabayashi +2
Comet 103P/Hartley 2 has diurnally controlled, CO2-driven activity on the tip of the small lobe of its bilobate nucleus. Such activity is unique among the comet nuclei visited by s…
Dynamic Sublimation Pressure and the Catastrophic Breakup of Comet ISON
Jordan K. Steckloff, Brandon C. Johnson, Timothy Bowling +4
Previously proposed mechanisms have difficulty explaining the disruption of Comet C/2012 S1 (ISON) as it approached the Sun. We describe a novel cometary disruption mechanism where…
