A parallel gravitational N-body kernel
Simon Portegies Zwart, Steve McMillan, Derek Groen +3
We describe source code level parallelization for the {\tt kira} direct gravitational -body integrator, the workhorse of the {\tt starlab} production environment for simulating…
Star cluster disruption by giant molecular clouds
M. Gieles, S. F. Portegies Zwart, H. Baumgardt +4
We investigate encounters between giant molecular clouds (GMCs) and star clusters. We propose a single expression for the energy gain of a cluster due to an encounter with a GMC, v…
Three-body encounters in the Galactic centre: the origin of the hypervelocity star SDSS J090745.0+024507
Alessia Gualandris, Simon Portegies Zwart, Michael Sipior
Hills (1988) predicted that runaway stars could be accelerated to velocities larger than 1000 km/s by dynamical encounters with the supermassive black hole (SMBH) in the Galactic c…
Recycled pulsars with black hole companions: the high mass analogues of PSR B2303+46
M. S. Sipior, S. Portegies Zwart, G. Nelemans
We investigate the possibility that mass transfer early in the evolution of a massive binary can effect a reversal of the end states of the two components, resulting in a neutron s…
Simulating the Early Evolution of the Hard X-Ray Properties of a Young Stellar Population
M. S. Sipior, M. Eracleous, S. Sigurdsson
We present an X-ray binary population synthesis model, and use it to simulate the evolution of X-ray binaries formed in a burst of star formation of duration 20 Myr and star-format…
