The interaction of core-collapse supernova ejecta with a companion star
The progenitors of many CCSNe are expected to be in binary systems. After the SN explosion, the companion may suffer from mass stripping and be shock heated as a result of the impact of the SN ejecta.

A Fluvio‐Lacustrine Environment Preserved in the Jezero Crater Inlet Channel, Neretva Vallis, Mars
Abstract Martian fluvial valleys provide evidence for the surface flow of liquid water, making them a key target for rover‐based investigations of ancient habitability. The Mars 2020 Perseverance rover spent ∼85 sols exploring the Bright Angel formation, exposed across the floor of Neretva Vallis: the western inlet channel of Jezero crater.

The γ-rays that accompanied GW170817 and the observational signature of a magnetic jet breaking out of NS merger ejecta [PDF]
We present the first relativistic MHD numerical simulation of a magnetic jet that propagates through and emerges from the dynamical ejecta of a binary neutron star merger.

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.

Abstract We investigated the regolith parent rock (“protolith”) properties of Mare Tranquillitatis and Marius Hills on the Moon, utilizing lunar pit craters (“lua”) to contextualize observations of rock abundance and crater degradation. We discovered a significant difference in underlying materials: the region around the Tranquillitatis lua is ...

This study of recent exploration drillcore reveals two sequences separated by a disconformity. Basal alluvial fan to shallow marine lithofacies suggest reactivation of basement faults, and a distinct upwelling signature points to a flooded margin, controlled by differential subsidence of diverse Proterozoic lithosphere.
