Core collapse in massive scalar-tensor gravity
Roxana Rosca-Mead, Ulrich Sperhake, Christopher J. Moore +3
This paper provides an extended exploration of the inverse-chirp gravitational-wave signals from stellar collapse in massive scalar-tensor gravity reported in [Phys. Rev. Lett. {\b…
Long-lived inverse chirp signals from core collapse in massive scalar-tensor gravity
Ulrich Sperhake, Christopher J. Moore, Roxana Rosca +3
This letter considers stellar core collapse in massive scalar--tensor theories of gravity. The presence of a mass term for the scalar field allows for dramatic increases in the rad…
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…
Black hole-neutron star mergers at realistic mass ratios: Equation of state and spin orientation effects
Francois Foucart, M. Brett Deaton, Matthew D. Duez +7
Black hole-neutron star mergers resulting in the disruption of the neutron star and the formation of an accretion disk and/or the ejection of unbound material are prime candidates…
Gravitational Wave Extraction in Simulations of Rotating Stellar Core Collapse
Christian Reisswig, Christian D. Ott, Ulrich Sperhake +1
We perform simulations of general relativistic rotating stellar core collapse and compute the gravitational waves (GWs) emitted in the core bounce phase of three representative mod…
