Life is But a Stream: The Distribution of Planetary Systems Along Stellar Streams and their Properties
Jeremy J. Webb, Milica Ivetic, Maxwell X. Cai +2
The majority of discovered exoplanets have been observed orbiting field stars as opposed to within a star cluster. To determine whether the lack of observed exoplanets in star clus…
Individual chaotic behaviour of the S-stars in the Galactic centre
Sam J. Beckers, Colin M. Poppelaars, Veronica S. Ulibarrena +2
Located at the core of the Galactic Centre, the S-star cluster serves as a remarkable illustration of chaos in dynamical systems. The long-term chaotic behaviour of this system can…
The origin and evolution of wide Jupiter Mass Binary Objects in young stellar clusters
Simon Portegies Zwart, Erwan Hochart
The recently observed population of 540 free-floating Jupiter-mass objects, including 40 dynamically soft pairs in the Trapezium cluster have raised interesting questions on their…
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…
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…
