Numerical Simulation of the Elastic–Plastic Ejection from Grooved Aluminum Surfaces Under Double Supported Shocks Using the SPH Method

Applied Sciences
The ejection of disturbed surfaces under multiple shocks is a critical phenomenon in pyrotechnic and inertial confinement fusion. In this study, the elastic–plastic ejection from grooved aluminum surfaces under double supported shocks was investigated ...

Hubble Space Telescope Proper Motion Measurements of Supernova Remnant N132D: Center of Expansion and Age

The Astrophysical Journal, 2023
We present proper motion measurements of the oxygen-rich ejecta of the LMC supernova remnant N132D using two epochs of Hubble Space Telescope Advanced Camera for Surveys data spanning 16 years.

Expansion Velocity of Ejecta in Tycho's Supernova Remnant Measured by Doppler Broadened X-ray Line Emission

, 2010
We show that the expansion of ejecta in Tycho's supernova remnant (SNR) is consistent with a spherically symmetric shell, based on Suzaku measurements of the Doppler broadened X-ray emission lines. All the strong K_alpha line emission show broader widths

Visualization of sneeze ejecta: steps of fluid fragmentation leading to respiratory droplets

Experiments in Fluids, 2016
Coughs and sneezes feature turbulent, multiphase flows that may contain pathogen-bearing droplets of mucosalivary fluid. As such, they can contribute to the spread of numerous infectious diseases, including influenza and SARS.

Nucleosynthesis in dynamical and torus ejecta of compact binary mergers

, 2015
We present a comprehensive study of r-process element nucleosynthesis in the ejecta of compact binary mergers (CBMs) and their relic black-hole (BH)-torus systems.

Deep Learning‐Based Automated Segmentation of Layered Crater Ejecta on Mars

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Layered crater ejecta (LCE) with fluidization on Mars is generally believed to be related to the near‐surface ice‐bearing deposits. The improvement in the resolution of planetary image data has led to the discovery of more and more LCE, providing support for further research on the formation and geological significance of layered ejecta ...

Properties of Kilonovae from Dynamical and Post-merger Ejecta of Neutron Star Mergers [PDF]

, 2017
Ejected material from neutron star mergers gives rise to electromagnetic emission powered by radioactive decays of r-process nuclei, the so-called kilonova or macronova.

The Three-Dimensional Expansion of the Ejecta from Tycho's Supernova Remnant

, 2017
We present the first three-dimensional measurements of the velocity of various ejecta knots in Tycho's supernova remnant, known to result from a Type Ia explosion.

The Influence of Interior Structure and Thermal State on Impact Melt Generation Upon Large Impacts Onto Terrestrial Planets

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract We investigate the melt production of planetary impacts as a function of planet size (R/REarth $R/{R}_{\text{Earth}}$ = 0.1–1.5), impactor size (L $L$ = 1–1,000 km), and core size ratio (Rcore/R ${R}_{\text{core}}/R$ = 0.2–0.8) using a combination of parameterized convection models and fully dynamical 2D impact simulations.

The ejecta of η Carinae [PDF]

Symposium - International Astronomical Union, 2003
Since New Year's Eve 1998, we have been studying η Carinae and the surrounding complex ejecta with the HST-stis instrument. Angular resolution of 0.1″ and spectral resolving power R = 5000-118000 have revealed a multitude of emission and absorption lines identified from many heavy elements.
