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…
