Abundances and Transients from Neutron Star-White Dwarf Mergers
Mark Alexander Kaltenborn, Chris L. Fryer, Ryan T. Wollaeger +3
We systematically investigate the mergers of neutron star-white dwarf binaries from beginning to end, with focus on the properties of the inflows and outflows in accretion disks an…
Axisymmetric Radiative Transfer Models of Kilonovae
Oleg Korobkin, Ryan Wollaeger, Christopher Fryer +9
The detailed observations of GW170817 proved for the first time directly that neutron star mergers are a major production site of heavy elements. The observations could be fit by a…
The Nucleosynthetic Yields of Core-Collapse Supernovae, prospects for the Next Generation of Gamma-Ray Astronomy
Sydney Andrews, Chris L. Fryer, Samuel W. Jones +2
Though the neutrino-driven convection model for the core-collapse explosion mechanism has received strong support in recent years, there are still many uncertainties in the explosi…
Impact of Pulsar and Fallback Sources on Multifrequency Kilonova Models
Ryan T. Wollaeger, Chris L. Fryer, Christopher J. Fontes +6
We explore the impact of pulsar electromagnetic dipole and fallback accretion emission on the luminosity of a suite of kilonova models. The pulsar models are varied over pulsar mag…
Gamma-rays from kilonova: a potential probe of r-process nucleosynthesis
Oleg Korobkin, Aimee M. Hungerford, Christopher L. Fryer +11
The mergers of compact binaries with at least one neutron star component are the potential leading sites of the production and ejection of -process elements. Discoveries of gala…
Composition Effects on Kilonova Spectra and Light Curves: I
Wesley Even, Oleg Korobkin, Christopher L. Fryer +7
The merger of neutron star binaries is believed to eject a wide range of heavy elements into the universe. By observing the emission from this ejecta, scientists can probe the ejec…
