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…
Viscous hydrodynamic evolution of neutron star merger accretion disks: a code comparison
Rodrigo Fernández, Oliver Just, Zewei Xiong +1
The accretion disk formed after a neutron star merger is an important contributor to the total ejecta from the merger, and hence to the kilonova and the -process yields of each…
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…
Measuring the Hubble constant with kilonovae using the Expanding Photosphere Method
Albert Sneppen, Darach Watson, Dovi Poznanski +3
While gravitational wave (GW) standard sirens from neutron star (NS) mergers have been proposed to offer good measurements of the Hubble constant, we show in this paper how a varia…
Production of -nuclei from -process seeds: the -process
Zewei Xiong, Gabriel Martínez-Pinedo, Oliver Just +1
We present a new nucleosynthesis process that may take place on neutron-rich ejecta experiencing an intensive neutrino flux. The nucleosynthesis proceeds similarly to the standard…
Spherical symmetry in the kilonova AT2017gfo/GW170817
Albert Sneppen, Darach Watson, Andreas Bauswein +5
The mergers of neutron stars expel a heavy-element enriched fireball which can be observed as a kilonova. The kilonova's geometry is a key diagnostic of the merger and is dictated…
