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…
Probing axion-like particles with multimessenger observations of neutron star mergers
Francesca Lecce, Alessandro Lella, Giuseppe Lucente +4
Axion-like particles (ALPs) can be copiously produced in binary neutron star (BNS) mergers through nucleon-nucleon bremsstrahlung if the ALP-nucleon couplings are sizable…
Impact of nuclear masses on r-process nucleosynthesis: bulk properties versus shell effects
Samuel A. Giuliani, Gabriel Martínez-Pinedo, Andreas Bauswein +1
We investigate the impact of the model estimating the masses of exotic nuclei on r-process nucleosynthesis, assessing the dependence of the abundance distribution on the specific p…
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…
Towards inferring the geometry of kilonovae
Christine E. Collins, Luke J. Shingles, Andreas Bauswein +11
Recent analysis of the kilonova, AT2017gfo, has indicated that this event was highly spherical. This may challenge hydrodynamics simulations of binary neutron star mergers, which u…
Self-consistent 3D radiative transfer for kilonovae: directional spectra from merger simulations
Luke J. Shingles, Christine E. Collins, Vimal Vijayan +7
We present three-dimensional radiative transfer calculations for the ejecta from a neutron star merger that include line-by-line opacities for tens of millions of bound-bound trans…
Impact of pions on binary neutron star mergers
Vimal Vijayan, Ninoy Rahman, Andreas Bauswein +2
We study the impact of pions in simulations of neutron star mergers and explore the impact on gravitational-wave observables. We model charged and neutral pions as a non-interactin…
End-to-end kilonova models of neutron-star mergers with delayed black-hole formation
Oliver Just, Vimal Vijayan, Zewei Xiong +6
We investigate the nucleosynthesis and kilonova properties of binary neutron-star (NS) merger models which lead to intermediate remnant lifetimes of ~0.1-1seconds until black-hole…
3D radiative transfer kilonova modelling for binary neutron star merger simulations
Christine E. Collins, Andreas Bauswein, Stuart A. Sim +5
The detection of GW170817 and the accompanying electromagnetic counterpart, AT2017gfo, have provided an important set of observational constraints for theoretical models of neutron…
Systematics of prompt black-hole formation in neutron star mergers
Andreas Bauswein, Sebastian Blacker, Georgios Lioutas +3
This study addresses the collapse behavior of neutron star (NS) mergers expressed through the binary threshold mass M_thr for prompt black hole (BH) formation, which we determine b…
Equation of state constraints from the threshold binary mass for prompt collapse of neutron star mergers
Andreas Bauswein, Sebastian Blacker, Vimal Vijayan +7
Using hydrodynamical simulations for a large set of high-density matter equations of state (EoSs) we systematically determine the threshold mass M_thres for prompt black-hole forma…
