Probing Shocked Ejecta in SN 1987A: A Novel Diagnostic Approach Using XRISM-Resolve

The Astrophysical Journal Letters
Supernova (SN) 1987A is one of the best candidates to exploit the capabilities of the freshly launched XRISM satellite. This celestial object offers the unique opportunity to study the evolution of an SN into a young supernova remnant. To date, the X-ray

Molecular dynamics simulations of ejecta production from sinusoidal tin surfaces under supported and unsupported shocks

, 2018
Micro-ejecta, an instability growth process, occurs at metal/vacuum or metal/gas interface when compressed shock wave releases from the free surface that contains surface defects.

Minimum velocity for impact ejecta to form secondaries on terrestrial bodies

Communications Earth & Environment
The minimum velocity (v) for impact ejecta to form secondary craters (secondaries) remains enigmatic, but it is a crucial parameter in untangling the fate of impact ejecta on planetary surfaces.

DART Impact Ejecta Plume Evolution: Implications for Dimorphos

The Planetary Science Journal
The NASA Double Asteroid Redirection Test (DART) spacecraft impacted the moon Dimorphos of the [65803] Didymos binary system and changed the binary orbit period, demonstrating asteroid deflection by a kinetic impact and indicating that more momentum was ...

Impacts of hemispherical granular targets: Implications for global impacts [PDF]

As impact excavation diameters subtend a nontrivial fraction of a planetary body, both the excavation process and ejecta emplacement may depart form the classical description of impacts into a planar surface.
