Spectroscopic r-Process Abundance Retrieval for Kilonovae III: Linking Spectral and Light Curve Modeling of the GW170817 Kilonova
Nicholas Vieira, John J. Ruan, Daryl Haggard +2
The observed spectra and light curves of the kilonova produced by the GW170817 binary neutron star merger provide complementary insights, but modeling both the spectral- and time-d…
Secular Outflows from 3D-MHD Hypermassive Neutron Star Accretion Disk Systems
Steven Fahlman, Rodrigo Fernández, Sharon Morsink
Magnetized hypermassive neutron stars (HMNSs) have been proposed as a way for neutron star (NS) mergers to produce high electron fraction, high velocity ejecta, as required by kilo…
Spectroscopic r-Process Abundance Retrieval for Kilonovae II: Lanthanides in the Inferred Abundance Patterns of Multi-Component Ejecta from the GW170817 Kilonova
Nicholas Vieira, John J. Ruan, Daryl Haggard +3
In kilonovae, freshly-synthesized -process elements imprint features on optical spectra, as observed in AT2017gfo, the counterpart to the GW170817 binary neutron star merger. Ho…
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…
