The mean free path approximation and stellar collisions in star clusters: Numerical exploration of the analytic rates and the role of perturbations on binary star mergers
Bastián Reinoso, Nathan W. C. Leigh, Carlos M. Barrera-Retamal +3
In this paper we compute predictions for the number of stellar collisions derived from analytic models based on the mean free path (MFP) approximation and compare them to the resul…
Starfall: A heavy rain of stars in 'turning on' AGN
B. McKernan, K. E. S. Ford, M. Cantiello +5
As active galactic nuclei (AGN) `turn on', some stars end up embedded in accretion disks around supermassive black holes (SMBHs) on retrograde orbits. Such stars experience strong…
Symmetry Breaking in Dynamical Encounters in the Disks of Active Galactic Nuclei
Yihan Wang, Barry McKernan, Saavik Ford +3
Active galactic nucleus (AGN) disks may be important sites of binary black hole (BBH) mergers. Here we show via numerical experiments with the high-accuracy, high precision code {\…
Hot Jupiter formation in dense clusters: secular chaos in multi-planetary systems
Yihan Wang, Rosalba Perna, Nathan W. C. Leigh +1
Exoplanetary observations reveal that the occurrence rate of hot Jupiters is correlated with star clustering. In star clusters, interactions between planetary systems and close fly…
Chaos in the vicinity of a singularity in the Three-Body Problem: The equilateral triangle experiment in the zero angular momentum limit
Hugo D. Parischewsky, Alessandro A. Trani, Nathan W. C. Leigh
We present numerical simulations of the gravitational three-body problem, in which three particles lie at rest close to the vertices of an equilateral triangle. In the unperturbed…
SpaceHub: A high-performance gravity integration toolkit for few-body problems in astrophysics
Yi-Han Wang, Nathan Leigh, Bin Liu +1
We present the open source few-body gravity integration toolkit {\tt SpaceHub}. {\tt SpaceHub} offers a variety of algorithmic methods, including the unique algorithms AR-Radau, AR…
Stellar collisions in flattened and rotating Pop. III star clusters
M. Z. C. Vergara, D. R. G. Schleicher, T. C. N. Boekholt +4
Fragmentation often occurs in disk-like structures, both in the early Universe and in the context of present-day star formation. Supermassive black holes (SMBHs) are astrophysical…
Spin misalignment of black hole binaries from young star clusters: implications for the origin of gravitational waves events
Alessandro Alberto Trani, Ataru Tanikawa, Michiko S. Fujii +2
Recent studies indicate that the progenitors of merging black hole (BH) binaries from young star clusters can undergo a common envelope phase just like isolated binaries. If the st…
Testing the Flux-based statistical prediction of the Three-Body Problem
Viraj Manwadkar, Barak Kol, Alessandro A. Trani +1
We present an extensive comparison between the statistical properties of non-hierarchical three-body systems and the corresponding three-body theoretical predictions. We perform an…
