Experimental Ejecta Emplacement in Variable Gravity and Its Effects on Landscape Evolution

The Planetary Science Journal
Ballistic sedimentation, the process by which impact-generated ejecta is deposited and interacts with planetary surfaces, remains understudied despite its significant role in landscape evolution on cratered terrain across the solar system.

Effect of Target Properties on Regolith Production

Remote Sensing
Based on the measurements of regolith thicknesses on the lunar maria (basalts), the lunar regolith was determined to have accumulated at a rate of about 1 m/Gyr since the era of the late heavy bombardment.

3D Reconstruction of DART Ejecta at Dimorphos Reveals an Anisotropic, Filamentary Structure

The Planetary Science Journal
We present a 3D reconstruction of the ejecta plume generated by the DART impact on Dimorphos based on LUKE images acquired by LICIACube. Using adaptive histogram equalization and geometric coregistration from multiple vantage points, we identified and ...

Ejecta velocities in twice-shocked liquid metals under extreme conditions: A hydrodynamic approach

Matter and Radiation at Extremes, 2019
We apply a hydrodynamic approach to analyze ejecta emanating from doubly shocked liquid metals. In particular, we are interested in characterizing ejecta velocities in such situations by treating the problem as a limiting case of the ...

Styles of ejecta emplacement under atmospheric conditions [PDF]

, 1991
Laboratory experiments provide essential first-order constraints on processes affecting ballistic ejecta and styles of ejecta emplacement under different atmospheric environments at planetary scales.

Ejecta Wakes from Companion Interaction in Type Ia Supernova Remnants

The Astrophysical Journal
Type Ia supernovae are triggered by accretion onto a white dwarf from a companion that is most likely Roche lobe–filling at the time of the explosion.

Spectroscopic r-process Abundance Retrieval for Kilonovae. II. Lanthanides in the Inferred Abundance Patterns of Multicomponent Ejecta from the GW170817 Kilonova

The Astrophysical Journal
In kilonovae, freshly synthesized r -process elements imprint features on optical spectra, as observed in AT2017gfo, the counterpart to the GW170817 binary neutron star merger.

The Effect of the Velocity Distribution on Kilonova Emission

The Astrophysical Journal
The electromagnetic emission from the nonrelativistic ejecta launched in neutron star mergers (either dynamically or through a disk wind) has the potential to probe both the total mass and composition of this ejecta.

Thermally distinct ejecta blankets from Martian craters [PDF]

, 1993
Utilizing the Termoskan data set of the Phobos '88 mission we have recognized a new feature on Mars: ejecta blanket distinct in the thermal infrared (EDITH).
