Contemporaneous formation of self-secondaries and layered ejecta deposits on Mars [PDF]

open access: goldCommunications Earth & Environment
Self-secondaries are secondary craters formed in cogenetic ejecta deposits. Bearing important information on cratering mechanics and the applicability of remote age-determination technique using crater statistics, the spatial distribution of self ...

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

open access: goldThe 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.

A numerical study of the interaction between two ejecta in the interplanetary medium: one- and two-dimensional hydrodynamic simulations [PDF]

open access: yesAnnales Geophysicae, 2004
We studied the heliospheric evolution in one and two dimensions of the interaction between two ejecta-like disturbances beyond the critical point: a faster ejecta 2 overtaking a previously launched slower ejecta 1. The study is based on a

Nepheline-kalsilite microperthites in ejecta from the Alban Hills (Italy) [PDF]

open access: yesBulletin of the Geological Society of Finland, 1985
Microprobe analyses carried out on exsolved nepheline and kalsilite phases of microperthites occurring in three ejecta from the Alban Hills (Roman comagmatic region) have shown: (1) a practically continuous compositional variation from Ks to Ne (bulk ...

Groove formation on Phobos from reimpacting orbital ejecta of the Stickney crater

open access: yesEarth and Planetary Physics, 2022
Numerous linear grooves have long been recognized as covering the surface of Phobos, but the mechanisms of their formation are still unclear. One possible mechanism is related to the largest crater on Phobos, the Stickney crater, whose impact ejecta may ...

Dynamic simulations of projectile penetration into granular medium

open access: yesMechanical Engineering Journal, 2014
Dynamic FEM and DEM simulations are carried out to investigate dynamic penetration of a projectile into a target of granular medium. Spatial distribution and time dependence of ejecta are clarified together with their trajectories in medium.
