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…
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…
Hyperonic degrees of freedom in binary neutron star mergers
Laura Tolos, Hristijan Kochankovski, Angels Ramos +3
We analyze the influence of hyperons in binary neutron star mergers considering several different equations of state that include hyperons. By running a large set of simulations, w…
Stellar properties indicating the presence of hyperons in neutron stars
Andreas Bauswein, Aristeidis Nikolaidis, Georgios Lioutas +7
We describe distinctive stellar features indicating the presence of hyperons in neutron stars as compared to purely nucleonic systems. A strongly negative curvature of the mass-rad…
The impact of hyperons on neutron star mergers: gravitational waves, mass ejection and black hole formation
Hristijan Kochankovski, Georgios Lioutas, Sebastian Blacker +3
We study the influence of hyperons in binary neutron star (NS) mergers considering a total of 14 temperature dependent equations of state (EoSs) models which include hyperonic degr…
