The origin of free-floating objects in the Galaxy
Simon F. Portegies Zwart
The Milky way Galaxy is brimming with free-floating objects, including stars, planets and planetesimals. For the purpose of this chapter, we define a free-floating object as a soli…
On time-dependent orbital complexity in gravitational N-body simulations
N. T. Faber, C. M. Boily, S. Portegies Zwart
We implement an efficient method to quantify time-dependent orbital complexity in gravitational -body simulations. The technique, which we name DWaTIM, is based on a discrete wa…
Hyperfast pulsars as the remnants of massive stars ejected from young star clusters
V. V. Gvaramadze, A. Gualandris, S. Portegies Zwart
Recent proper motion and parallax measurements for the pulsar PSR B1508+55 indicate a transverse velocity of ~1100 km/s, which exceeds earlier measurements for any neutron star. Th…
The Primordial Binary Population in OB Associations
M. B. N. Kouwenhoven, A. G. A. Brown, A. Gualandris +3
For understanding the process of star formation it is essential to know how many stars are formed as singles or in multiple systems, as a function of environment and binary paramet…
