Context. Hierarchical triple stars are ideal laboratories for studying the interplay between
orbital dynamics and stellar evolution. Both mass loss from stellar winds and strong …

Since its formulation by Sir Isaac Newton, the problem of solving the equations of motion for
three bodies under their own gravitational force has remained practically unsolved …

We study the chaotic-like behavior of cosmological simulations by quantifying how minute
perturbations grow over time and manifest as macroscopic differences in galaxy properties …

Close encounters between two bodies in a disc often result in a single orbital deflection.
However, within their Jacobi volumes, where the gravitational forces between the two bodies …

The evolution of galaxies is governed by equations with chaotic solutions: gravity and
compressible (magneto-) hydrodynamics. While this microscale chaos and stochasticity has …

We investigate the chaotic behaviour of the S-star cluster in the Galactic Centre using
precise N-body calculations, free from round-off or discretization errors. Our findings reveal …

Context. The three-body problem (3BP) poses a longstanding challenge in physics and
celestial mechanics. Despite the impossibility of obtaining general analytical solutions …

Aims. We perform a simulation using the Astrophysical Multipurpose Software Environment
of the Orion Trapezium star cluster in which the evolution of the stars and the dynamics of …

Astrophysical models of binary-black hole mergers in the universe require a significant
fraction of stellar-mass black holes (BHs) to receive negligible natal kicks to explain the …

Chaos is present in most stellar dynamical systems and manifests itself through the
exponential growth of small perturbations. Exponential divergence drives time irreversibility …
