Infrared emission from kilonovae: the case of the nearby short hard burst GRB 160821B [PDF]
, 2017 We present constraints on Ks-band emission from one of the nearest short hard gamma-ray bursts, GRB 160821B, at z=0.16, at three epochs. We detect a reddened relativistic afterglow from the jetted emission in the first epoch but do not detect any excess ...

AerospaceSafe landings are imperative to accomplish NASA’s Artemis goal to enable human exploration on the Moon, including sample collection missions. However, a process known as plume surface interaction (PSI) presents a significant hazard to lunar landings. PSI

Non-Equipartition of Energy, Masses of Nova Ejecta, and Type Ia Supernovae [PDF]
, 2001 The total masses ejected during classical nova eruptions are needed to answer two questions with broad astrophysical implications: Can accreting white dwarfs be pushed towards the Chandrasekhar mass limit to yield type Ia supernovae?

Light‑Driven Propulsion of Graphene Aerogels in Microgravity
Advanced Science, EarlyView.Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

High‐Fidelity Cretaceous‐Paleogene Boundary Investigations: Records of Impact and Transport
Geochemistry, Geophysics, GeosystemsThe Chicxulub impact on the Yucatán Peninsula triggered the end‐Cretaceous mass extinction 66 million years ago, but physical models still struggle to accurately describe ejecta generation and transport from this and other large meteorite impacts.

Advanced Energy Materials, EarlyView.This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

A Drone‐Based Thermophysical Investigation of Barringer Meteorite Crater Ejecta
Earth and Space ScienceImpact cratering processes are ubiquitous throughout our solar system, and the distribution and modification of impact ejecta are sensitive to variable environmental and geologic surface conditions.

Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments
Journal of Raman Spectroscopy, EarlyView.Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

, 2018 We perform long-term general relativistic neutrino radiation hydrodynamics simulations (in axisymmetry) for a massive neutron star (MNS) surrounded by a torus, which is a canonical remnant formed after the binary neutron star merger. We take into account

Mass Loss From Planetary Nebulae in Elliptical Galaxies [PDF]
, 2009 Early-type galaxies possess a dilute hot (2-10E6 K) gas that is probably the thermalized ejecta of the mass loss from evolving stars. We investigate the processes by which the mass loss from orbiting stars interacts with the stationary hot gas for the ...
