Many neutron stars are observed to be moving with spatial velocities, in excess of 500 km s-1. A number of mechanisms have been proposed to give neutron stars these high velocities. One of the leading classes of models proposed invokes asymmetries in the core of a massive star just prior to collapse. These asymmetries grow during the collapse, causing the resultant supernova to be also asymmetric. As the ejecta is launched, it pushes off (or "kicks") the newly formed neutron star. This Letter… 

Effects of Neutrino-driven Kicks on the Supernova Explosion Mechanism

We show that neutrino-driven pulsar kicks can increase the energy of the supernova shock. The observed large velocities of pulsars are believed to originate in the supernova explosion, either from


Using three-dimensional (3D) simulations of neutrino-powered supernova explosions, we show that the hydrodynamical kick scenario proposed by Scheck et al. on the basis of two-dimensional (2D) models

Neutron Star Formation

The nature of a neutron star differs based on whether the neutron star formed from the collapse of a white dwarf, the collapse of a ∼ 8 – 11M⊙ star, or the collapse of a more massive star (∼ 11 –

Multidimensional supernova simulations with approximative neutrino transport. I. Neutron star kicks and the anisotropy of neutrino-driven explosions in two spatial dimensions

We study hydrodynamic instabilities during the first seconds of core-collapse supernovae by means of 2D simulations with approximative neutrino transport and boundary conditions that parameterize the

Gravitational Waves from Stellar Collapse: Correlations to Explosion Asymmetries

The collapse of massive stars produces not only observable outbursts across the entire electromagnetic spectrum but, for Galactic (or near-Galactic) supernovae, detectable signals for ground-based

Natal kicks of stellar mass black holes by asymmetric mass ejection in fallback supernovae

Integrating trajectories of low-mass X-ray binaries containing black holes within the Galactic potential, Repetto, Davies & Sigurdsson recently showed that the large distances of some systems above

Neutron Star Kicks: Mechanisms and Observational Constraints

Observations over the last decade have shown that neutron stars (NSs) receive a kick velocity (of order a hundred to a thousand km s−1) at birth. The physical origin of the kicks and the related

Gravitational Radiation from Standing Accretion Shock Instability in Core-Collapse Supernovae

We present the results of numerical experiments in which we study how asphericities induced by the growth of the standing accretion shock instability (SASI) produce gravitational waveforms in the

Neutrino Oscillations, and the Origin of Pulsar Velocities and Dark Matter

Neutrino oscillations in a core-collapse supernova may be responsible for the observed rapid motions of pulsars. Three-dimensional numerical calculations show that, in the absence of neutrino

The Neutrino Bubble Instability: A Mechanism for Generating Pulsar Kicks

An explanation for the large random velocities of pulsars is presented. Like many other models, we propose that the momentum imparted to the star is given at birth. The ultimate source of energy is



Double Neutron Star Systems and Natal Neutron Star Kicks

We study the four double neutron star systems found in the Galactic disk in terms of the orbital characteristics of their immediate progenitors and the natal kicks imparted to neutron stars. Analysis

Pulsar Jets: Implications for Neutron Star Kicks and Initial Spins

We study implications for the apparent alignment of the spin axes, proper motion directions, and polarization vectors of the Crab and Vela pulsars. The spin axes are deduced from recent Chandra X-Ray

High birth velocities of radio pulsars

NEUTRON stars are usually born during the supernova explosion of a massive star. Any small asymmetry during the explosion can result in a substantial ‘kick’ velocity1 to the neutron star. Pulsars

Population Syntheses for Neutron Star Systems with Intrinsic Kicks

We use a Monte Carlo binary synthesis code to model the formation and evolution of neutron star systems including high-mass X-ray binaries, low-mass X-ray binaries, double neutron star systems, and

Pulsar recoil and gravitational radiation due to asymmetrical stellar collapse and explosion.

It is predicted that any recoils imparted to the neutron star at birth will result in a gravitational wave strain that does not go to zero with time, and there may be ``memory'' in the gravitational wave form from a protoneutron star that is correlated with its recoil and neutrino emissions.

THE observable interactions of neutron stars with their local environment provide an opportunity for measuring the properties of both relativistic pulsar winds and the surrounding interstellar

Neutrino-Nucleon Interactions in Magnetized Neutron-Star Matter: The Effects of Parity Violation

We study neutrino-nucleon scattering and absorption in a dense, magnetized nuclear medium. These are the most important sources of neutrino opacity governing the cooling of a proto-neutron star in

The runaway black hole GRO J1655-40 ⋆

We have used the Hubble Space Telescope to measure the motion in the sky and compute the galactocentric orbit of the black hole X-ray binary GRO J1655-40. The system moves with a runaway space

Mass Limits For Black Hole Formation

We present a series of two-dimensional core-collapse supernova simulations for a range of progenitor masses and different input physics. These models predict a range of supernova energies and compact

Inside the Supernova: A Powerful Convective Engine

Condensed Abstract: We present an extensive study of the inception of supernova explosions by following the evolution of the cores of two massive stars (15 Msun and 25 Msun) in two dimensions. Our
