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…
Full Transport Model of GW170817-Like Disk Produces a Blue Kilonova
Jonah M. Miller, Benjamin R. Ryan, Joshua C. Dolence +7
The 2017 detection of the inspiral and merger of two neutron stars in gravitational waves and gamma rays was accompanied by a quickly-reddening transient. Such a transient was pred…
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…
Understanding the Engines and Progenitors of Gamma-Ray Bursts
Chris L. Fryer, Nicole Lloyd-Ronning, Ryan Wollaeger +5
Our understanding of the engines and progenitors of gamma-ray bursts has expanded through the ages as a broader set of diagnostics has allowed us to test our understanding of these…
A line-binned treatment of opacities for the spectra and light curves from neutron star mergers
C. J. Fontes, C. L. Fryer, A. L. Hungerford +2
The electromagnetic observations of GW170817 were able to dramatically increase our understanding of neutron star mergers beyond what we learned from gravitational waves alone. The…
Synthetic Spectra of Pair-Instability Supernovae in 3D
E. Chatzopoulos, M. S. Gilmer, R. T. Wollaeger +2
Pair-Instability Supernovae (PISNe) may signal the deaths of extremely massive stars in the local Universe or massive primordial stars after the end of the Cosmic Dark Ages. Hydrod…
