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 ...

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

Constraint on the ejecta mass for a black hole-neutron star merger event candidate S190814bv [PDF]
We derive the upper limit to the ejecta mass of S190814bv, a black hole-neutron star merger candidate, through the radiative transfer simulations for kilonovae with the realistic ejecta density profile as well as the detailed opacity and heating rate ...

Dynamic simulations of projectile penetration into granular medium
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.

The X-ray Iron Emission from Tycho's Supernova Remnant [PDF]
We present the results of broadband fits to the X-ray spectrum of Tycho's supernova remnant obtained by the Solid-State Imaging Spectrometers on the ASCA Observatory.

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 ...

GRB 060206: hints of precession of the central engine? [PDF]
Aims. The high-redshift (z=4.048) gamma-ray burst GRB 060206 showed unusual behavior, with a significant rebrightening by a factor of ~4 at about 3000 s after the burst. We argue that this rebrightening implies that the central engine became active again
