Star Cluster Ecology VIII. -- Dynamically Forming S-Type and Centauri-like Systems
Erwan Hochart, Simon Portegies Zwart
Aims: To analyse the impact of dynamically formed binaries emerging naturally from various star cluster environments on already established planetary systems. Methods: Numerical si…
A triple-induced merger in T Ori C, solves the proplyd lifetime problem and the curiously young shell of M42
Maite Wilhelm, Alessandro Alberto Trani, Simon Portegies Zwart
There has long been a tension between the stellar ages in the Orion Nebula Cluster and the rapid external photoevaporation of its protoplanetary discs. Recently, the shell of the O…
Spin-disc misalignment drives periodic accretion and pulse profile asymmetry in X-ray pulsars
A. A. Mushtukov, V. Ganesh, S. S. Tsygankov +2
We investigate magnetospheric accretion in disc-fed X-ray pulsars assuming that the neutron star spin axis is not perpendicular to the disc plane. We focus on X-ray pulsars, where…
Validating direct solvers for Newton's gravitational N-body problem, and the systematic comparison between IEEE floating point and Posits
Simon Portegies Zwart
We present a systematic comparison between arbitrary precise arithmetic and integration, IEEE-754 compliant floating point arithmetic (fp16, bfp16, fp32, double precision fp64, and…
Planet-moon ejections in close stellar encounters
Yannick Badoux, Simon Portegies Zwart
Free-floating planet-moon pairs (FFPMs) may form when planetary systems experience close stellar encounters. We quantify moon-retention probabilities and ejection cross sections fo…
Recoiling Black Holes I. Burst of Observables
Erwan Hochart, Simon Portegies Zwart
We aim to investigate the tidal disruption and gravitational wave events shortly after a massive black hole binary merges in the galactic centre and whose remnant black hole is eje…
