Beta-Particle Transport and Thermalization in Kilonova Ejecta with Detailed Atomic Microphysics
Zachary L. Andalman, Christopher L. Fryer, Christopher J. Fontes +2
When two neutron stars collide, they eject material containing heavy nuclei formed by the rapid neutron capture process (-process). As these nuclei decay, they power a bright op…
Radiation-Hydrodynamics Effects in an Inhomogeneous Medium
Christopher L. Fryer, Paul A. Keiter, Vidushi Sharma +9
Radiation flow through an inhomogeneous medium is critical in a wide range of physics and astronomy applications from transport across cloud layers on the earth to the propagation…
Introducing STARDIS: An Open and Modular Stellar Spectral Synthesis Code
Joshua V. Shields, Wolfgang Kerzendorf, Isaac G. Smith +7
We introduce a new 1D stellar spectral synthesis Python code called stardis. stardis is a modular, open-source radiative transfer code that is capable of spectral synthesis from ne…
Helioseismic inference of the solar radiative opacity
Gaël Buldgen, Jean-Christophe Pain, Philippe Cossé +18
The Sun is the most studied of all stars, and thus constitutes a benchmark for stellar models. However, our vision of the Sun is still incomplete, as illustrated by the current deb…
Multidisciplinary Science in the Multimessenger Era
Eric Burns, Christopher L. Fryer, Ivan Agullo +82
Astrophysical observations of the cosmos allow us to probe extreme physics and answer foundational questions on our universe. Modern astronomy is increasingly operating under a hol…
