MHD Simulations of Core Collapse Supernovae with Cosmos++

Shizuka Akiyama, Jay D. Salmonson

We performed 2D, axisymmetric, MHD simulations with Cosmos++ in order to examine the growth of the magnetorotational instability (MRI) in core--collapse supernovae. We have initial…

Evolution of the First Stars with Dark Matter Burning

Sung-Chul Yoon, Fabio Iocco, Shizuka Akiyama

Recent theoretical studies have revealed the possibly important role of the capture and annihilation process of weakly interacting massive particles (WIMPs) for the first stars. Us…

The Physics of Wind-Fed Accretion

Christopher W. Mauche, Duane A. Liedahl, Shizuka Akiyama +1

We provide a brief review of the physical processes behind the radiative driving of the winds of OB stars and the Bondi-Hoyle-Lyttleton capture and accretion of a fraction of the s…

Supernova Asymmetries

J. Craig Wheeler, Justyn R. Maund, Shizuka Akiyama

All core collapse supernovae are strongly aspherical. The "Bochum event," with velocity components displaced symmetrically about the principal H line, strongly suggests that SN…

Hydrodynamic and Spectral Simulations of HMXB Winds

Christopher W. Mauche, Duane A. Liedahl, Shizuka Akiyama +1

We describe preliminary results of a global model of the radiatively-driven photoionized wind and accretion flow of the high-mass X-ray binary Vela X-1. The full model combines FLA…

De-leptonization and Non-Axisymmetric Instabilities in Core Collapse Supernovae

J. Craig Wheeler, Shizuka Akiyama

The timescale of de-leptonization by neutrino loss and associated contraction of a proto-neutron star is short compared to the time to progagate a shock through the helium core of…
