A Very Fast Symplectic Integrator for Planetary Systems: WHFast512 in x86 Assembly
Rishit Dagli, Hanno Rein
Long-term integrations of planetary systems are used in a variety of astrophysical applications, for example to determine a system's stability. In this paper, we describe significa…
Rings in the Sky: Orbital Data Centres and Potential Impacts to Astronomy and the Sky
Aaron C. Boley, Samantha M. Lawler, Hanno Rein
Megaconstellations of orbital data centres (ODCs) have the potential to fundamentally change the sky without a concerted mitigation effort. Potential changes include producing larg…
Stellar separation shapes spin-orbit alignment in visual binaries
Michael Poon, Dang Pham, Marta L. Bryan +2
Stellar binaries may form through several formation pathways, including disk or core fragmentation. Their spin-orbit angles are a signature of formation, although individual measur…
Real time, cross platform visualizations with zero dependencies for the N-body package REBOUND
Hanno Rein
Visualizations have become an indispensable part of the scientific process. A vibrant ecosystem of visualization tools exists, catering to a wide variety of different needs. Real-t…
Democratic heliocentric coordinates underestimate the rate of instabilities in long-term integrations of the Solar System
Hanno Rein, Kavi Dey, Daniel Tamayo
Wisdom-Holman (WH) integrators are symplectic operator-splitting methods widely used for long-term N-body simulations of planetary systems. Most implementations use either Jacobi c…
On the statistical convergence of N-body simulations of the Solar System
Hanno Rein, Garett Brown, Mei Kanda
Most direct N-body integrations of planetary systems use a symplectic integrator with a fixed timestep. A large timestep is desirable in order to speed up the numerical simulations…
