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…
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…
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…
Impact of nuclear masses on r-process nucleosynthesis: bulk properties versus shell effects
Samuel A. Giuliani, Gabriel MartÃnez-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…
Low- instabilities in differentially rotating neutron stars resembling merger remnants
Georgios Lioutas, Panagiotis Iosif, Andreas Bauswein +1
We construct constant rest-mass sequences of equilibrium models of differentially rotating neutron stars which resemble binary neutron star post-merger remnants. For a more realist…
Hadron Physics Opportunities at FAIR
J. G. Messchendorp, F. Nerling, P. Achenbach +103
This White Paper outlines a coordinated, decade-spanning programme of hadron and QCD studies anchored at the GSI/FAIR accelerator complex. Profiting from intense deuteron, proton a…
