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…
On the evolution and fate of supermassive stars
L. R. Yungelson, E. P. J. van den Heuvel, Jorick S. Vink +2
We study the evolution and fate of solar composition supermassive stars in the mass range 60 - 1000 Msun. Our study is relevant both for very massive objects observed in young stel…
Harvesting graphics power for MD simulations
J. A. van Meel, A. Arnold, D. Frenkel +2
We discuss an implementation of molecular dynamics (MD) simulations on a graphic processing unit (GPU) in the NVIDIA CUDA language. We tested our code on a modern GPU, the NVIDIA G…
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 primordial binary population II: Recovering the binary population for intermediate mass stars in Sco OB2
M. B. N. Kouwenhoven, A. G. A. Brown, S. F. Portegies Zwart +1
We characterize the binary population in the young and nearby OB association Scorpius OB2 using available observations of visual, spectroscopic, and astrometric binaries with inter…
