Cosmic String Detection via Microlensing of Stars
David F. Chernoff, S. -H. Henry Tye
Cosmic superstrings are produced towards the end of the brane inflation. If the string tension is low enough, loops tend to be relatively long-lived. The resultant string network i…
On the Origin of the most massive stars around R136
B. R. Brandl, S. Portegies Zwart, A. J. F. Moffat +1
We discuss the signature of a peculiar constellation of very massive stars at a projected distance of 2-3 pc around R136a. We discuss various scenarios for its possible origin, suc…
Explosive Disruption of Polytropes: a One Dimensional Hydrodynamic Calculation
Mark Wyman, David Chernoff, Ira Wasserman
We study explosions of stars using a one-dimensional Lagrangian hydrodynamics code. We calculate how much mass is liberated as a function of the energy of explosion for a variety o…
The Velocity Distribution of Isolated Radio Pulsars
Z. Arzoumanian, D. F. Chernoff, J. M. Cordes
(Abridged) We infer the velocity distribution of radio pulsars by modelling their birth, evolution, and detection in large-scale 0.4 GHz pulsar surveys, and by comparing model dist…
Pulsar Jets: Implications for Neutron Star Kicks and Initial Spins
Dong Lai, David F. Chernoff, James M. Cordes
We study implications for the apparent alignment of the spin axes, proper-motions, and polarization vectors of the Crab and Vela pulsars. The spin axes are deduced from recent Chan…
Effects of magnetic fields on radiatively overstable shock waves
Paul A. Kimoto, David F. Chernoff
We discuss high-resolution simulations of one-dimensional, plane-parallel shock waves with mean speeds between 150 and 240 km/s propagating into gas with Alfven velocities up to 40…
Neutron Star Population Dynamics.II: 3D Space Velocities of Young Pulsars
J. M. Cordes, David F. Chernoff
We use astrometric, distance and spindown data on pulsars to: (1) estimate three-dimensional velocity components, birth distances from the galactic plane, and ages of individual ob…
Molecule Formation In and On Grains.I: Physical Regimes
Amir Levinson, David F. Chernoff, Edwin E. Salpeter
We study molecular hydrogen formation in and on solids. We construct a model with surface sites and bulk sites capable of describing (1) the motion and exchange of H and H_2 betwee…
Neutron Star Population Dynamics.I: Millisecond Pulsars
J. M. Cordes, David F. Chernoff
We study the field millisecond pulsar (MSP) population to infer its intrinsic distribution in spin period and luminosity and to determine its spatial distribution within the Galaxy…
Radiative instabilities in simulations of spherically symmetric supernova blast waves
Paul A. Kimoto, David F. Chernoff
High-resolution simulations of the cooling regions of spherically symmetric supernova remnants demonstrate a strong radiative instability. This instability, whose presence is depen…
An adaptive hierarchical particle-mesh code with isolated boundary conditions
Sergio Gelato, David F. Chernoff, Ira Wasserman
This article describes a new, fully adaptive Particle-Multiple-Mesh numerical simulation code developed primarily for simulations of small regions (such as a group of galaxies) in…
Truncation of the Binary Distribution Function in Globular Cluster Formation
E. Vesperini, D. F. Chernoff
We investigate a population of primordial binaries during the initial stage of evolution of a star cluster. For our calculations we assume that equal mass stars form rapidly in a t…
Convergence properties of finite-difference hydrodynamics schemes in the presence of shocks
Paul A. Kimoto, David F. Chernoff
We investigate asymptotic convergence in the~ limit as a tool for determining whether numerical computations involving shocks are accurate. We use one-dimensi…
Polarized Scattering in the Vicinty of Galaxies
B. W. Murphy, D. F. Chernoff
Some bright cD galaxies in cluster cooling flows have Thomson optical depths exceeding 0.01. A few percent of their luminosity is scattered and appears as diffuse polarized emissio…
