Transition to the Radiative Phase in Supernova Remnants
The evolution of a supernova remnant through the transition from an adiabatic Sedov-Taylor blast wave to a radiative pressure-driven snowplow phase is studied using one- and two-dimensional
Colliding Winds from Early-Type Stars in Binary Systems
The dynamics of the wind and shock structure formed by the wind collision in early-type binary systems is examined by means of a 2D hydrodynamics code, which self-consistently accounts for radiative
Stability of Standing Accretion Shocks, with an Eye toward Core-Collapse Supernovae
We examine the stability of standing, spherical accretion shocks. Accretion shocks arise in core-collapse supernovae (the focus of this paper), star formation, and accreting white dwarfs and neutron
PULSAR WIND NEBULAE IN EVOLVED SUPERNOVA REMNANTS
For pulsars similar to the one in the Crab Nebula, most of the energy input to the surrounding wind nebula occurs on a timescale 103 yr; during this time, the nebula expands into freely expanding
Pulsar spins from an instability in the accretion shock of supernovae
TLDR
Sufficient angular momentum is deposited on the proto-neutron star to generate a final spin period consistent with observations, even beginning with spherically symmetrical initial conditions, and weakens the assumed correlation between the rotational periods of supernova progenitor cores and pulsar spin.
The shadow wind in high-mass X-ray binaries
We present hydrodynamic simulations of the most X-ray luminous high-mass X-ray binary systems, such as Cen X-3 and SMC X-1. These models illustrate the presence of both a normal radiatively driven
RCW 86: A TYPE Ia SUPERNOVA IN A WIND-BLOWN BUBBLE
We report results from a multi-wavelength analysis of the Galactic supernova remnant RCW?86, the proposed remnant of the supernova of 185 A.D. We show new infrared observations from the Spitzer Space
A Million Second Chandra View of Cassiopeia A
We introduce a million second observation of the supernova remnant Cassiopeia A with the Chandra X-Ray Observatory. The bipolar structure of the Si-rich ejecta (northeast jet and southwest
A Deep Chandra Observation of Kepler’s Supernova Remnant: A Type Ia Event with Circumstellar Interaction
We present initial results of a 750 ks Chandra observation of the remnant of Kepler's supernova of AD 1604. The strength and prominence of iron emission, together with the absence of O-rich ejecta,
The Spherical Accretion Shock Instability in the Linear Regime
We use time-dependent, axisymmetric, hydrodynamic simulations to study the linear stability of the stalled, spherical accretion shock that arises in the postbounce phase of core-collapse supernovae.
