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…
Helium as an Indicator of the Neutron-Star Merger Remnant Lifetime and its Potential for Equation of State Constraints
Albert Sneppen, Oliver Just, Andreas Bauswein +9
The time until black hole formation in a binary neutron-star (NS) merger contains invaluable information about the nuclear equation of state (EoS) but has thus far been difficult t…
Helium features are inconsistent with the spectral evolution of the kilonova AT2017gfo
Albert Sneppen, Rasmus Damgaard, Darach Watson +3
The spectral features observed in kilonovae (KNe) reveal the elemental composition and the velocity structures of matter ejected from neutron star mergers. In the spectra of the ki…
The asymmetry of white dwarf double detonations and the observed scatter around the Phillips relation
Alexander Holas, Friedrich K. Roepke, Rüdiger Pakmor +6
Recent Type Ia supernova (SN Ia) simulations featuring a double detonation scenario have managed to reproduce the overall trend of the Phillips relation reasonably well. However, m…
