We use relativistic hydrodynamic numerical calculations to study the interaction between a jet and a homologous outflow produced dynamically during binary neutron star mergers. We quantify how the…
Super-Eddington stellar winds driven by near-surface energy deposition
- E. Quataert, R. Fernández, D. Kasen, Hannah Klion, B. Paxton
- Physics
- 21 September 2015
We develop analytic and numerical models of the properties of super-Eddington stellar winds, motivated by phases in stellar evolution when super-Eddington energy deposition (via, e.g., unstable…
NEUTRINO-DRIVEN TURBULENT CONVECTION AND STANDING ACCRETION SHOCK INSTABILITY IN THREE-DIMENSIONAL CORE-COLLAPSE SUPERNOVAE

- 24 September 2014
We conduct a series of numerical experiments into the nature of three-dimensional (3D) hydrodynamics in the postbounce stalled-shock phase of core-collapse supernovae using 3D general-relativistic…
A diagnostic for localizing red giant differential rotation
- Hannah Klion, E. Quataert
- Physics
- 5 August 2016
We present a simple diagnostic that can be used to constrain the location of the differential rotation in red giants with measured mixed mode rotational splittings. Specifically, in red giants with…
Supernova seismology: gravitational wave signatures of rapidly rotating core collapse
- J. Fuller, Hannah Klion, E. Abdikamalov, C. Ott
- Physics
- 27 January 2015
Gravitational waves (GW) generated during a core-collapse supernova open a window into the heart of the explosion. At core bounce, progenitors with rapid core rotation rates exhibit a characteristic…
The effect of jet–ejecta interaction on the viewing angle dependence of kilonova light curves
- Hannah Klion, P. Duffell, D. Kasen, E. Quataert
- Physics
- 15 December 2020
The merger of two neutron stars produces an outflow of radioactive heavy nuclei. Within a second of merger, the central remnant is expected to also launch a relativistic jet, which shock-heats and…
The impact of r-process heating on the dynamics of neutron star merger accretion disc winds and their electromagnetic radiation

Neutron star merger accretion discs can launch neutron-rich winds of >10−2M⊙. This ejecta is a prime site for r-process nucleosynthesis, which will produce a range of radioactive heavy nuclei. The…
