Late-time emission-line profiles from kilonova models
S. A. Sim, O. Just, Z. Xiong +10
Numerical simulations suggest that neutron star mergers eject material with complex, non-spherical density and composition distributions. Here we use two-dimensional configurations…
Exploring the diversity of kilonovae with 3D radiative transfer I. The polar direction
Christine E. Collins, Luke J. Shingles, Vimal Vijayan +7
We present 3D kilonova radiative transfer simulations for a series of binary neutron star merger models. The masses of the neutron stars are varied as well as the total mass of the…
Light Travel Time Effects in Kilonova Models
F. McNeill, S. A. Sim, C. E. Collins +4
The extremely rapid evolution of kilonovae results in spectra that change on an hourly basis. These spectra are key to understanding the processes occurring within the event, but t…
Electron-Impact Excitation of Zirconium I-III in support of Neutron Star Merger Diagnostics
M. McCann, C. P. Ballance, F. McNeill +2
Recent observation and analysis of kilonovae (KNe) spectra as a result of neutron star mergers require accurate and complete atomic structure and collisional data for interpretatio…
Luminosity predictions for the first three ionisation stages of W, Pt and Au to probe potential sources of emission in kilonova
M. McCann, L. P. Mulholland, Z. Xiong +7
A large number of R-matrix calculations of electron impact excitation for heavy elements (Z > 70) have been performed in recent years for applications in fusion and astrophysics re…
Collisional and Radiative Data for Tellurium ions in Kilonovae modelling and Laboratory Benchmarks
Leo Patrick Mulholland, Fiona McNeill, Stuart A. Sim +2
Tellurium is a primary candidate for the identification of the 2.1 m emission line in kilonovae (KNe) spectra AT2017gfo and GRB230307A. Despite this, there is currently an insu…
