He awa whiria: the tidal streams of interstellar objects
John C. Forbes, Michele T. Bannister, Chris Lintott +5
Upcoming surveys are likely to discover a new sample of interstellar objects (ISOs) within the Solar System, but questions remain about the origin and distribution of this populati…
On the origin of transition disk cavities: Pebble-accreting protoplanets vs Super-Jupiters
Shuo Huang, Nienke van der Marel, Simon Portegies Zwart
Protoplanetary disks surrounding young stars are the birth places of planets. Among them, transition disks with inner dust cavities of tens of au are sometimes suggested to host ma…
Binary Disruption and Ejected Stars from Hierarchical Star Cluster Assembly
Claude Cournoyer-Cloutier, Jeremy Karam, Alison Sills +2
We simulate mergers between star clusters embedded within their natal giant molecular cloud. We extract initial conditions from cloud-scale simulations of cluster formation and int…
On the suppression of giant planet formation around low-mass stars in clustered environments
Shuo Huang, Simon Portegies Zwart, Maite J. C. Wilhelm
Context: Current exoplanet formation studies tend to overlook the birth environment of stars in clustered environments. The effect of this environment on the planet-formation proce…
Massive star cluster formation III. Early mass segregation during cluster assembly
Brooke Polak, Mordecai-Mark Mac Low, Ralf S. Klessen +6
Mass segregation is seen in many star clusters, but whether massive stars form in the center of a cluster or migrate there dynamically is still debated. N-body simulations have sho…
Venice: a multi-scale operator-splitting algorithm for multi-physics simulations
Maite Wilhelm, Simon Portegies Zwart
We present {\sc Venice}, an operator splitting algorithm to integrate a numerical model on a hierarchy of timescales. {\sc Venice} allows a wide variety of different physical proce…
Binary-single interactions with different mass ratios
Bruno Rando Forastier, Daniel Marín Pina, Mark Gieles +2
Dynamical interactions in star clusters are an efficient mechanism to produce the coalescing binary black holes (BBHs) that have been detected with gravitational waves (GWs). We wa…
Massive star cluster formation II. Runaway stars as fossils of sub-cluster mergers
Brooke Polak, Mordecai-Mark Mac Low, Ralf S. Klessen +6
Two main mechanisms have classically been proposed for the formation of runaway stars. In the binary supernova scenario (BSS), a massive star in a binary explodes as a supernova, e…
Isles of regularity in a sea of chaos amid the gravitational three-body problem
Alessandro Alberto Trani, Nathan W. C. Leigh, Tjarda C. N. Boekholt +1
The three-body problem (3BP) poses a longstanding challenge in physics and celestial mechanics. Despite the impossibility of obtaining general analytical solutions, statistical the…
Magnetospheric Flows in X-ray Pulsars I: Instability at super-Eddington regime of accretion
A. A. Mushtukov, A. Ingram, V. F. Suleimanov +5
Within the magnetospheric radius, the geometry of accretion flow in X-ray pulsars is shaped by a strong magnetic field of a neutron star. Starting at the magnetospheric radius, acc…
