White dwarfs represent the final state of evolution for most stars1–3. Certain classes of white dwarfs pulsate4,5, leading to observable brightness variations, and analysis of these variations with theoretical stellar models probes their internal s

This chapter explores the largely parallel progressions of person memory and stereotyping research in social cognition, with particular focus on spontaneous inferences drawn from descriptions of behavior or social group membership. We consider the po

This chapter offers a toolkit of concrete methods and practices that researchers can use to advance open, replicable, and inclusive science. Part I describes how to calibrate confidence in a significant finding to the strength of evidence provided by

We discuss the tilted Abel Transform (special case of the X-ray Transform for objects that are cylindrically-symmetric) and its adjoint and how these can be used to develop model-based iterative reconstruction algorithms.

High purity polycrystalline tantalum (Ta) was shocked through 1 to 3.5 Mbar pressures creating Richtmyer-Meshkov unstable interfaces that were used to determine the dynamic material strength. The experiments were performed on the Omega laser at the U

Hydrodynamic instability experiments allow access to material properties at extreme conditions, where strain rates exceed 105 s−1 and pressures reach 100 GPa. Current hydrodynamic instability experimental methods require in-flight radiography to im

We examine the performance of pure boron, boron carbide, high density carbon, and boron nitride ablators in the polar direct drive exploding pusher (PDXP) platform. The platform uses the polar direct drive configuration at the National Ignition Facil

Dynamic compression of composite materials is of scientific interest because the mechanical mismatch between internal phases challenges continuum theories. Typical assumptions about steady wave propagation and quasi-instantaneous state changes requir

Over the last six years many experiments have been done at the National Ignition Facility to measure the Hugoniot of materials, such as CH plastic at extreme pressures, up to 800 Mbar. The “Gbar” design employs a strong spherically converging sho

Heterogeneous materials do not respond mechanically to an impulse in the manner of homogeneous metals and alloys. Wave propagation in a microstructure with chemically distinct identities, that are only in incidental contact with each other, is a comp
