Ejecta‐Modulated Bubble Dynamics Play a Dominant Role in Stone Retropulsion [PDF]
Cavitation bubbles generated by laser absorption in liquids collapse violently, producing high‐speed jets, toroidal bubbles, and shock waves that induce material erosion and object displacement.

Shocked quartz in distal ejecta from the Ries impact event (Germany) found at ~ 180 km distance, near Bernhardzell, eastern Switzerland [PDF]
Impact ejecta formation and emplacement is of great importance when it comes to understanding the process of impact cratering and consequences of impact events in general. Here we present a multidisciplinary investigation of a distal impact ejecta layer,

Evolutionary signatures in complex ejecta and their driven shocks [PDF]
We examine interplanetary signatures of ejecta-ejecta interactions. To this end, two time intervals of inner-heliospheric (≤1AU) observations separated by 2 solar cycles are chosen where ejecta/magnetic clouds are in the process of interacting to ...

Splashing of impacting drops produces a myriad of secondary spray droplets, which generate aerosols during rain on the ocean and can cause health hazards during the spraying of pesticides or enhance the droplet transmission of disease. Determining the size and number of the finest splashed droplets is therefore of practical interest.

MAGNETOHYDRODYNAMIC EFFECTS IN RELATIVISTIC EJECTA [PDF]
We study the problem of deceleration of an arbitrarily magnetized relativistic ejecta in a static unmagnetized medium and its connection to the physics of gamma-ray bursts (GRBs). By computing exact solutions of the Riemann problem describing this scenario, we find that with the same initial Lorentz factor, the reverse shock becomes progressively ...

Ejecta Wakes from Companion Interaction in Type Ia Supernova Remnants
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.

Model of Double Asteroid Redirection Test Impact Ejecta Plume Observations [PDF]
The Double Asteroid Redirection Test (DART) spacecraft will impact the moon Dimorphos of the [65803] Didymos binary in order to demonstrate asteroid deflection by a kinetic impactor.

Molecules in Supernova Ejecta [PDF]
AbstractThe first molecules detected at infrared wavelengths in the ejecta of a Type II supernova, namely SN1987A, consisted of CO and SiO. Since then, confirmation of the formation of these two species in several other supernovae a few hundred days after explosion has been obtained.

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