Post-Outburst Radio Observations of the High Magnetic Field Pulsar PSR J1119-6127
Walid A. Majid, Aaron B. Pearlman, Tatyana Dobreva +4
We have carried out high frequency radio observations of the high magnetic field pulsar PSR J1119-6127 following its recent X-ray outburst. While initial observations showed no evi…
Dynamics, nucleosynthesis, and kilonova signature of black hole - neutron star merger ejecta
Rodrigo Fernández, Francois Foucart, Daniel Kasen +3
We investigate the ejecta from black hole - neutron star mergers by modeling the formation and interaction of mass ejected in a tidal tail and a disk wind. The outflows are neutron…
SpECTRE: A Task-based Discontinuous Galerkin Code for Relativistic Astrophysics
Lawrence E. Kidder, Scott E. Field, Francois Foucart +11
We introduce a new relativistic astrophysics code, SpECTRE, that combines a discontinuous Galerkin method with a task-based parallelism model. SpECTRE's goal is to achieve more acc…
Simulations of inspiraling and merging double neutron stars using the Spectral Einstein Code
Roland Haas, Christian D. Ott, Bela Szilagyi +11
We present results on the inspiral, merger, and post-merger evolution of a neutron star - neutron star (NSNS) system. Our results are obtained using the hybrid pseudospectral-finit…
The Influence of Neutrinos on r-Process Nucleosynthesis in the Ejecta of Black Hole-Neutron Star Mergers
Luke F. Roberts, Jonas Lippuner, Matthew D. Duez +6
During the merger of a black hole and a neutron star, baryonic mass can become unbound from the system. Because the ejected material is extremely neutron-rich, the r-process rapidl…
Dynamical Mass Ejection from Binary Neutron Star Mergers
David Radice, Filippo Galeazzi, Jonas Lippuner +3
We present fully general-relativistic simulations of binary neutron star mergers with a temperature and composition dependent nuclear equation of state. We study the dynamical mass…
