Ejecta from Dimorphos following the DART mission impact significantly increased the brightness of the Didymos–Dimorphos system, allowing us to examine subsurface material.

Linking a distal ejecta with its source crater: a probabilistic approach applied to tektites
We propose a probabilistic approach to gauge the plausibility of a genetic link between a distal ejecta and a known impact structure, considering the only possible alternative that the distal ejecta could originate from an unknown impact site.

The Three-Dimensional Structure of Cassiopeia A [PDF]
We used the Spitzer Space Telescope's Infrared Spectrograph to map nearly the entire extent of Cassiopeia A between 5-40 micron. Using infrared and Chandra X-ray Doppler velocity measurements, along with the locations of optical ejecta beyond the forward

Scour Pits in the Medusae Fossae Formation and Olympus Mons Region on Mars
Abstract The Medusae Fossae Formation (MFF) covers a region of Mars located to the southwest of the Olympus Mons shield volcano. The nature of this formation has been under debate for over 30 years. In order to better understand the MFF, we investigated scour pits or V‐shaped depressions carved into many places across the MFF.

Impact of ejecta morphology and composition on the electromagnetic signatures of neutron star mergers [PDF]
The electromagnetic transients accompanying compact binary mergers (gamma-ray bursts, after-glows and 'macronovae') are crucial to pinpoint the sky location of gravitational wave sources.

China's Chang'e‐6 (CE‐6) mission has returned the first‐ever lunar farside samples from a mare plain on the southern Apollo basin floor. The crater statistics of the CE‐6 mare unit and the provenance of the samples are crucial in interpreting the CE‐6 ...

Properties of Neutrino-driven Ejecta from the Remnant of a Binary Neutron Star Merger: Pure Radiation Hydrodynamics Case [PDF]
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.

Mega-ejecta on asteroid Vesta [PDF]
[1] Asteroid 4 Vesta, sometimes called the “smallest terrestrial planet”, will be orbited next July by NASA's Dawn mission. This will be the first time a small planet is visited by a spacecraft, and novel geological structures are expected. A key issue regarding Vesta (mean diameter 530 km) is to what extent its geology is dominated by the ∼460 km ...

Modelling Surtseyan Ejecta [PDF]
<p>Surtseyan ejecta are formed in shallow sub-aqueous volcanic eruptions. They occur when water, containing a slurry of previously erupted material, is washed into the volcanic vent. This slurry is incorporated into the magma and ejected from the volcano inside a ball of magma. These magma bombs containing entrained material are called, Surtseyan
