VELOCITY-DEPENDENT CATASTROPHIC DISRUPTION CRITERIA FOR PLANETESIMALS (2009, methodology): “Low-velocity (1–300 m s−1) collisions are modeled with PKDGRAV, an N-body gravity code (Richardson et al. 2000; Leinhardt et al. 2000; Stadel 2001; Leinhardt & Richardson 2002).”
Fragment properties at the catastrophic disruption threshold: The effect of the parent body’s internal structure (2009, methodology): “Since we are dealing with a fairly large number of bodies that we want to follow over long periods of time, we use a parallel N -body hierarchical tree code (Richardson et al. 2000).”
Spin-up of rubble-pile asteroids: Disruption, satellite formation, and equilibrium shapes (2012, methodology): “Many of the simulation parameters used in this work can be found in the literature ( e . g Richardson et al .”
FORMATION OF KUIPER BELT BINARIES BY GRAVITATIONAL COLLAPSE (2010, methodology): “Our simulations of gravitational collapse were performed with a modified version of the N -body cosmological code PKDGRAV (Stadel 2001), described in Richardson et al. (2000) (also see Leinhardt et al. 2000, Leinhardt & Richardson 2002).”
THE LINK BETWEEN PLANETARY SYSTEMS, DUSTY WHITE DWARFS, AND METAL-POLLUTED WHITE DWARFS (2012, methodology): “The simulations use the N-body code pkdgrav, originally used for cosmological simulations, to provide a very fast, parallelized tree for computing interparticle gravity (Richardson et al. 2000).”
Rubble Pile Asteroids (2018, background): “…models, those capable of modeling a gravitational aggregate, a body held together entirely by its self-gravity, but without some of the complicating dynamics introduced by surface penetrations and interactions of the constituent particles (Asphaug and Benz 1994,1996; Richardson et al. 1998,2000).”
Formation of planetary debris discs around white dwarfs – I. Tidal disruption of an extremely eccentric asteroid (2014, methodology): “For a more extensive discussion on the properties of this integrator, see Richardson et al. (2000).”
Size-frequency distributions of fragments from SPH/N-body simulations of asteroid impacts: Comparison with observed asteroid families (2007, methodology): “…the outcomes of the SPH models are handed off as the initial conditions for N -body gravitational simulations using the code pkdgrav (Richardson et al., 2000; Leinhardt and Richardson, 2002; Leinhardt et al., 2000; Stadel, 2001). pkdgrav is a scalable, parallel tree code for…”
The formation of asteroid satellites in large impacts: Results from numerical simulations (2004, methodology): “To track the trajectories of collision fragments we use a modified version of the cosmological N -body code pkdgrav, featured in Richardson et al., 2000, (also see Leinhardt et al., 2000; Leinhardt and Richardson, 2002). pkdgrav is a scalable, parallel tree code designed for ease of portability and…”
Gravitational N-Body Simulations (2003, methodology): “One such code called PKDGRAV has been adapted from cosmological applications to the case of planetesimal and ring simulations [Richardson et al., 2000].”
Full numerical simulations of catastrophic small body collisions (2008, methodology): “In these simulations, we have employed the parallelized, Lagrangian, hierarchical tree code pkdgrav (Richardson et al. 2000; Leinhardt et al. 2000) to complete the gravitational reaccumulation phase of the collision.”
