Discrepancies between Chandrasekhar's theory of relaxation and -body simulations
Kerwann Tep, Douglas C. Heggie
The paper compares Chandrasekian orbit‑averaged relaxation theory with high‑precision N‑body simulations of anisotropic globular clusters, finding reduced but still position‑depend…
Very long-term relaxation of harmonic 1D self-gravitating systems
Kerwann Tep, Jean-Baptiste Fouvry, Christophe Pichon
One-dimensional self-gravitating systems admit genuine thermodynamical equilibria. For systems with strictly monotonic orbital frequency profile, the Landau and Balescu-Lenard theo…
Modeling Globular Cluster Stellar Streams with a Basis-Expansion N-body Code
Brian T. Cook, Kerwann Tep, Carl L. Rodriguez +6
Globular cluster stellar streams probe galaxy-formation processes and can potentially reveal the distribution of dark matter in galaxies. In many theoretical studies, streams are m…
KRIOS: A new basis-expansion -body code for collisional stellar dynamics
Kerwann Tep, Brian T. Cook, Carl L. Rodriguez +4
The gravitational -body problem is a nearly universal problem in astrophysics which, despite its deceptive simplicity, still presents a significant computational challenge. For…
Linear response of rotating and flattened stellar clusters: the oblate Kuzmin-Kutuzov Stäckel family
Kerwann Tep, Christophe Pichon, Michael S Petersen
This paper investigates the linear response of a series of spheroidal stellar clusters, the Kuzmin-Kutuzov Stäckel family, which exhibit a continuous range of flattening and rotat…
