Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued
evolution of rotating helium stars, M α≳ 10 M⊙, in which iron-core collapse does not produce …

We continue our study of the possible production of supernovae and a variety of high-energy
transients by black hole formation in massive stars endowed with rotation: the" collapsar …

We present a two-dimensional grid-based hydrodynamic simulation of a thin, viscous, locally
isothermal corotating disk orbiting an equal-mass Newtonian binary point mass on a fixed …

We examine the propagation of two-dimensional relativistic jets through the stellar progenitor
in the collapsar model for gamma-ray bursts (GRBs). Each jet is parameterized by a radius …

Over the past decade, our physical understanding of γ-ray bursts (GRBs) has progressed
rapidly, thanks to the discovery and observation of their long-lived afterglow emission. Long-…

By numerically integrating the compressible Navier–Stokes equations in two dimensions,
we calculate the criterion for gap formation by a very low mass (q∼ 10− 4) protoplanet on a …

We present the results of two-dimensional (2D) hydrodynamical simulations of circumbinary
disk accretion using the finite-volume code DISCO. This code solves the 2D viscous Navier–…

… viewed off-axis (Rhoads 1997; van Eerten & MacFadyen 2011), suggestions include optical
afterglows … Full details of the numerical scheme may be found in Zrake & MacFadyen (2012). …

A wide variety of astrophysical phenomena involve the flow of turbulent magnetized gas with
relativistic velocity or energy density. Examples include gamma-ray bursts, active galactic …

The merger of binary neutron stars (BNSs) can lead to large amplifications of the magnetic
field due to the development of turbulence and instabilities in the fluid, such as the Kelvin–…
