Relativistic dynamical friction in stellar systems

C Chiari, P Di Cintio - Astronomy & Astrophysics, 2023 - aanda.org

Chandrasekhar to the case of relativistic velocities and velocity distributions, also accounting …

Introducing a new multi-particle collision method for the evolution of dense stellar systems-Crash-test N-body simulations

P Di Cintio, M Pasquato, H Kim, SJ Yoon - Astronomy & Astrophysics, 2021 - aanda.org
Context. Stellar systems are broadly divided into collisional and non-collisional categories.
While the latter are large-N systems with long relaxation timescales and can be simulated …
