X-ray Emission from Strongly Asymmetric Circumstellar Material in the Remnant of Kepler's Supernova
Mary T. Burkey, Stephen P. Reynolds, Kazimierz J. Borkowski +1
Kepler's supernova remnant resulted from a thermonuclear explosion, but is interacting with circumstellar material (CSM) lost from the progenitor system. We describe a statistical…
Axisymmetric Ab Initio Core-Collapse Supernova Simulations of 12-25 M_sol Stars
Stephen W. Bruenn, Anthony Mezzacappa, W. Raphael Hix +7
We present an overview of four ab initio axisymmetric core-collapse supernova simulations employing detailed spectral neutrino transport computed with our CHIMERA code and initiate…
Three-dimensional numerical investigations of the morphology of type Ia SNRs
D. C. Warren, J. M. Blondin
We explore the morphology of Type Ia supernova remnants (SNRs) using three-dimensional hydrodynamics modeling and an exponential density profile. Our model distinguishes ejecta fro…
Neutron star masses from hydrodynamical effects in obscured sgHMXBs
A. Manousakis, R. Walter, J. M. Blondin
A population of obscured supergiant High Mass X-ray Binaries (sgHMXBs) has been discovered by INTEGRAL. X-ray wind tomography of IGR J17252-3616 inferred a slow wind velocity to ac…
Hoyle-Lyttleton Accretion in Three Dimensions
John M. Blondin, Eric Raymer
We investigate the stability of gravitational accretion of an ideal gas onto a compact object moving through a uniform medium at Mach 3. Previous three-dimensional simulations have…
Turbulence and magnetic field amplification from spiral SASI modes in core-collapse supernovae
E. Endeve, C. Y. Cardall, R. D. Budiardja +2
The stationary accretion shock instability (SASI) plays a central role in modern simulations of the explosion phase of core-collapse supernovae (CCSNe). It may be key to realizing…
