Scaling laws for the geometry of an impact-induced magma ocean

Miki Nakajima, Gregor J. Golabek, Kai Wünnemann +6

Here, we develop scaling laws for (1) the distribution of impact-induced heat within the mantle and (2) shape of the impact-induced melt based on more than 100 smoothed particle hy…

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…

A Self-Consistent Model of the Circumstellar Debris Created by a Giant Hypervelocity Impact in the HD172555 System

B. C. Johnson, C. M. Lisse, C. H. Chen +8

Spectral modeling of the large infrared excess in the Spitzer IRS spectra of HD 172555 suggests that there is more than 10^19 kg of sub-micron dust in the system. Using physical ar…
