Gargantuan chaotic gravitational three-body systems II. Dependence on angular momentum and astrophysical scale
Tjarda C. N. Boekholt, Simon F. Portegies Zwart
Recently we estimated that about 5 percent of supermassive black hole triple systems are fundamentally unpredictable. These gargantuan chaotic systems are able to exponentially mag…
Black Hole Binaries in AGN Accretion Discs II: Gas Effects on Black Hole Satellite Scatterings
Connar Rowan, Henry Whitehead, Tjarda Boekholt +2
The black hole (BH) binaries in active galactic nuclei (AGN) are expected to form mainly through scattering encounters in the ambient gaseous medium. Recent simulations, including…
Punctuated chaos and the unpredictability of the Galactic center S-star orbital evolution
Simon Portegies Zwart, Tjarda Boekholt, Douglas Heggie
We investigate the chaotic behavior of the S-star cluster in the Galactic center using precise -body calculations, free from round-off or discretization errors. Our findings rev…
Punctuated Chaos and Indeterminism in Self-gravitating Many-body Systems
Tjarda C. N. Boekholt, Simon F. Portegies Zwart, Douglas C. Heggie
Dynamical chaos is a fundamental manifestation of gravity in astrophysical, many-body systems. The spectrum of Lyapunov exponents quantifies the associated exponential response to…
Stirred, not shaken: Star cluster survival in the slingshot scenario
D. Matus Carrillo, M. Fellhauer, T. Boekholt +2
We investigate the effects of an oscillating gas filament on the dynamics of its embedded stellar clusters. Motivated by recent observational constraints, we model the host gas fil…
On the Reliability of N-body Simulations
Tjarda Boekholt, Simon Portegies Zwart
The general consensus in the N-body community is that statistical results of an ensemble of collisional N-body simulations are accurate, even though individual simulations are not.…
