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…
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…
Kilonova Light-Curve Interpolation with Neural Networks
Yinglei Peng, Marko Ristić, Atul Kedia +7
Kilonovae are the electromagnetic transients created by the radioactive decay of freshly synthesized elements in the environment surrounding a neutron star merger. To study the fun…
On a spectral method for -particle bound excitation collisions in kilonovae
Ryan T. Wollaeger, Chris L. Fryer, Robert Chiodi +9
The interaction of -particles with the weakly ionized plasma background is an important mechanism for powering the kilonova transient signal from neutron star mergers. For this…
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…
The Effect of the Velocity Distribution on Kilonova Emission
Chris L. Fryer, Aimee L. Hungerford, Ryan T. Wollaeger +7
The electromagnetic emission from the non-relativistic ejecta launched in neutron star mergers (either dynamically or through a disk wind) has the potential to probe both the total…
Impact of a minority relativistic electron tail interacting with a thermal plasma containing high-atomic-number impurities
Nathan A. Garland, Hyun-Kyung Chung, Christopher J. Fontes +6
A minority relativistic electron component can arise in both laboratory and naturally-occurring plasmas. In the presence of high-atomic-number ion species, the ion charge state dis…
