Bound Outflows, Unbound Ejecta, and the Shaping of Bipolar Remnants during Stellar Coalescence [PDF]
Astrophysical Journal, 2018 Recent observations have revealed that the remnants of stellar-coalescence transients are bipolar. This raises the questions of how these bipolar morphologies arise and what they teach us about the mechanisms of mass ejection during stellar mergers and ...

Layering Structures in the Porous Material Beneath the Chang'e‐3 Landing Site
Earth and Space Science, 2020 The lunar penetrating radar (LPR) onboard the Chinese Chang'e‐3 (CE‐3) mission obtained high‐resolution profile data for the continuous ejecta deposits of the Ziwei crater.

Analysis of Late--time Light Curves of Type IIb, Ib and Ic Supernovae
, 2015 The shape of the light curve peak of radioactive--powered core--collapse "stripped--envelope" supernovae constrains the ejecta mass, nickel mass, and kinetic energy by the brightness and diffusion time for a given opacity and observed expansion velocity.

Spatial identification of the overionized plasma in W49B [PDF]
, 2010 Recent Suzaku X-ray observations of the ejecta-dominated supernova remnant W49B have shown that in the global spectrum there is a clear indication for the presence of overionized plasma whose physical origin is still under debate.

Molecules in Supernova Ejecta [PDF]
Proceedings of the International Astronomical Union, 2011 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.

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Interactions of solar wind dynamic pressure (SWDP) discontinuities with Earth's magnetosphere cause geomagnetic Sudden Commencements (SCs). Typically, positive/negative SCs occur at low latitudes due to enhancements/reductions in SWDP.

Impact‐Generated Mixing, Melting and Vaporization of the Early Earth's Crust
Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract Earth's primary accretion was followed by a protracted flux of interplanetary collisions by leftover planetesimals. The effects of the largest collisions—with bodies possibly exceeding 1,000 km diameter—would have been devastating for terrestrial near‐surface environments.

Properties of Neutrino-driven Ejecta from the Remnant of a Binary Neutron Star Merger: Pure Radiation Hydrodynamics Case [PDF]
, 2017 We performed general relativistic, long-term, axisymmetric neutrino radiation hydrodynamics simulations for the remnant formed after a binary neutron star merger, which consists of a massive neutron star and a torus surrounding it.

Radiation Front Sweeping the Ambient Medium of Gamma-Ray Bursts [PDF]
, 2001 Gamma-ray bursts (GRBs) are emitted by relativistic ejecta from powerful cosmic explosions. Their light curves suggest that the gamma-ray emission occurs at early stages of the ejecta expansion, well before it decelerates in the ambient medium.
