Step-size effect in the time-transformed leapfrog integrator on elliptic and hyperbolic orbits
Long Wang, Keigo Nitadori
A drift-kick-drift (DKD) type leapfrog symplectic integrator applied for a time-transformed separable Hamiltonian (or time-transformed symplectic integrator; TSI) has been known to…
PeTar: a high-performance N-body code for modeling massive collisional stellar systems
Long Wang, Masaki Iwasawa, Keigo Nitadori +1
The numerical simulations of massive collisional stellar systems, such as globular clusters (GCs), are very time-consuming. Until now, only a few realistic million-body simulations…
A slow-down time-transformed symplectic integrator for solving the few-body problem
Long Wang, Keigo Nitadori, Junichiro Makino
An accurate and efficient method dealing with the few-body dynamics is important for simulating collisional N-body systems like star clusters and to follow the formation and evolut…
The survival of star clusters with black hole subsystems
Long Wang
Recent observations have detected top-heavy IMFs in dense star forming regions like the Arches cluster. Whether such IMFs also exist in old dense stellar systems like globular clus…
The possible role of stellar mergers for the formation of multiple stellar populations in globular clusters
Long Wang, Pavel Kroupa, Koh Takahashi +1
Many possible scenarios for the formation of multiple stellar populations (MSP) in globular clusters (GCs) have been discussed so far, including the involvement of asymptotic giant…
Merging black holes in young star clusters
Ugo N. Di Carlo, Nicola Giacobbo, Michela Mapelli +4
Searching for distinctive signatures, which characterize different formation channels of binary black holes (BBHs), is a crucial step towards the interpretation of current and futu…
