The Astrophysical Journal, 2023 We investigate the influence of Toomre’s Q parameter on the bar-forming dynamics of the Maclaurin disk using N -body simulations. According to Toomre’s criterion, the local velocity dispersion parametrized by Q ≥ 1 is required to suppress the local ...

GENGA II: GPU planetary N-body simulations with non-Newtonian forces and high number of particles [PDF]
, 2022 We present recent updates and improvements of the graphical processing unit (GPU) N-body code GENGA. Modern state-of-the-art simulations of planet formation require the use of a very high number of particles to accurately resolve planetary growth and to ...

Self-consistent Spin, Tidal, and Dynamical Equations of Motion in the REBOUNDx Framework
The Astrophysical Journal, 2023 We introduce self-consistent spin, tidal, and dynamical equations of motion into REBOUNDx , a library of additional effects for the popular N -body integrator REBOUND .

Halo modelling in chameleon theories [PDF]
, 2014 We analyse modelling techniques for the large-scale structure formed in scalar-tensor theories of constant Brans-Dicke parameter which match the concordance model background expansion history and produce a chameleon suppression of the gravitational ...

Confirming Resonance in Three Transiting Systems
The Astronomical Journal, 2023 Although resonant planets have orbital periods near commensurability, resonance is also dictated by other factors, such as the planets’ eccentricities and masses, and therefore must be confirmed through a study of the system’s dynamics.

Collisional Growth and Fragmentation of Dust Aggregates. II. Mass Distribution of Icy Fragments
The Astrophysical Journal, 2023 By performing N -body simulations, we investigated the fundamental processes of collisions between dust aggregates composed of submicron-sized icy dust monomers.

Dark energy perturbations in N-body simulations [PDF]
, 2019 We present N-body simulations which are fully compatible with general relativity, with dark energy consistently included at both the background and perturbation level.

Jovian Trojan N-Body Simulations [PDF]
The Jovian Trojans are two swarms of asteroids, one ahead and one behind the orbit of Jupiter. These data are simulations of these objects over the 4.5 gya of the the solar system.

Relativistic initial conditions for N-body simulations [PDF]
, 2017 Initial conditions for (Newtonian) cosmological N-body simulations are usually set by re-scaling the present-day power spectrum obtained from linear (relativistic) Boltzmann codes to the desired initial redshift of the simulation.

N-body Simulations of Galaxy Formation [PDF]
Symposium - International Astronomical Union, 1988 Modern N-body techniques allow the study of galaxy formation in the wider context of the formation of large-scale structure in the Universe. The results of such a study within the cold dark matter cosmogony are described. Dark galactic halos form at relatively recent epochs.
