A free-fall-based switching criterion for P^3 T N-body methods in collisional stellar systems
Long Wang, David M. Hernandez, Zepeng Zheng +1
The PT scheme is a hybrid method for simulating gravitational -body systems. It combines a fast particle-tree (PT) algorithm for long-range forces with a high-accuracy parti…
No influence of passing stars on paleoclimate reconstructions over the past 56 million years
Richard E. Zeebe, David M. Hernandez
Passing stars (also called stellar flybys) have notable effects on the solar system's long-term dynamical evolution, injection of Oort cloud comets into the solar system, propertie…
Collisional Fragmentation Support in TRACE
Tiger Lu, Haniyeh Tajer, David M. Hernandez +3
We present improved collision support for TRACE, a state-of-the-art hybrid integrator in REBOUND. TRACE now supports collisional fragmentation and can handle both removing and addi…
TRACE: a code for Time-Reversible Astrophysical Close Encounters
Tiger Lu, David M. Hernandez, Hanno Rein
We present TRACE, an almost time-reversible hybrid integrator for the planetary N-body problem. Like hybrid symplectic integrators, TRACE can resolve close encounters between parti…
AI can identify Solar System instability billions of years in advance
Dorian S. Abbot, J. D. Laurence-Chasen, Robert J. Webber +2
Rare event schemes require an approximation of the probability of the rare event as a function of system state. Finding an appropriate reaction coordinate is typically the most cha…
Multiple timestep reversible -body integrators for close encounters in planetary systems
David M. Hernandez, Walter Dehnen
We present new almost time-reversible integrators for solution of planetary systems consisting of "planets" and a dominant mass ("star"). The algorithms can be considered adaptive…
