Pairing mechanisms for binary stars
M. B. N. Kouwenhoven, A. G. A. Brown, S. P. Goodwin +2
Knowledge of the binary population in stellar groupings provides important information about the outcome of the star forming process in different environments. Binarity is also a k…
On the origin of hyperfast neutron stars
V. V. Gvaramadze, A. Gualandris, S. Portegies Zwart
We propose an explanation for the origin of hyperfast neutron stars (e.g. PSR B1508+55, PSR B2224+65, RX J0822-4300) based on the hypothesis that they could be the remnants of a sy…
A runaway collision in a young star cluster as the origin of the brightest supernova
Simon Portegies Zwart, Edward P. J. van den Heuvel
Supernova 2006gy in the galaxy NGC 1260 is the most luminous one recorded \cite{2006CBET..644....1Q, 2006CBET..647....1H, 2006CBET..648....1P, 2006CBET..695....1F}. Its progenitor…
Distributed N-body Simulation on the Grid Using Dedicated Hardware
Derek Groen, Simon Portegies Zwart, Steve McMillan +1
We present performance measurements of direct gravitational N -body simulation on the grid, with and without specialized (GRAPE-6) hardware. Our inter-continental virtual organizat…
The present day mass function in the central region of the Arches cluster
Simon Portegies Zwart, Evghenii Gaburov, Hui-Chen Chen +1
We study the evolution of the mass function in young and dense star clusters by means of direct N-body simulations. Our main aim is to explain the recent observations of the relati…
High Performance Direct Gravitational N-body Simulations on Graphics Processing Unit I: An implementation in Cg
Simon Portegies Zwart, Robert Belleman, Peter Geldof
We present the results of gravitational direct -body simulations using the commercial graphics processing units (GPU) NVIDIA Quadro FX1400 and GeForce 8800GTX, and compare the r…
