We present a first exploration of the results of neutron star-black hole mergers using black hole masses in the most likely range of 7M_⊙ –10M_⊙, a neutrino leakage scheme, and a modeling of the…
Black-hole-neutron-star mergers: Disk mass predictions

Determining the final result of black-hole\char21{}neutron-star mergers, and, in particular, the amount of matter remaining outside the black hole at late times and its properties, has been one of…
Remnant baryon mass in neutron star-black hole mergers: Predictions for binary neutron star mimickers and rapidly spinning black holes

Gravitational-wave (GW) and electromagnetic (EM) signals from the merger of a neutron star (NS) and a black hole (BH) are a highly anticipated discovery. We present a simple formula, validated with…

We investigate the long-term evolution of black hole accretion disks formed in neutron star mergers. These disks expel matter that contributes to an $r$-process kilonova, and can produce relativistic…
Signatures of hypermassive neutron star lifetimes on r-process nucleosynthesis in the disc ejecta from neutron star mergers

We investigate the nucleosynthesis of heavy elements in the winds ejected by accretion discs formed in neutron star mergers. We compute the element formation in disc outflows from hypermassive…
Post-merger evolution of a neutron star-black hole binary with neutrino transport

We present a first simulation of the post-merger evolution of a black hole-neutron star binary in full general relativity using an energy-integrated general-relativistic truncated moment formalism…
Equation of state effects in black hole–neutron star mergers

The merger dynamics of a black hole–neutron star (BHNS) binary is influenced by the neutron star equation of state (EoS) through the latter's effect on the neutron star's radius and on the character…
Black hole-neutron star mergers at realistic mass ratios: Equation of state and spin orientation effects
- F. Foucart, M. Deaton, S. Teukolsky
- Physics
- 19 December 2012
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 for the joint…
Black hole-neutron star mergers: Effects of the orientation of the black hole spin
- F. Foucart, M. Duez, L. Kidder, S. Teukolsky
- Physics
- 23 July 2010
The spin of black holes in black hole-neutron star binaries can have a strong influence on the merger dynamics and the post-merger state; a wide variety of spin magnitudes and orientations are…
Evolution of spin direction of accreting magnetic protostars and spin-orbit misalignment in exoplanetary systems

Abstract Recent observations have shown that in many exoplanetary systems the spin axis of the parent star is misaligned with the planet's orbital axis. These have been used to argue against the…
