Discrepancies between Chandrasekhar's theory of relaxation and -body simulations
Kerwann Tep, Douglas C. Heggie
Globular clusters are systems which are known to be particularly well described by two-body relaxation. In recent decades many studies have shown that Chandrasekhar's orbit-average…
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 rotati…
Non-resonant relaxation of rotating globular clusters
Kerwann Tep, Jean-Baptiste Fouvry, Christophe Pichon
The long-term relaxation of rotating, spherically symmetric globular clusters is investigated through an extension of the orbit averaged Chandrasekhar non-resonant formalism. A com…
Predicting the linear response of self-gravitating stellar spheres and discs with LinearResponse.jl
Michael S. Petersen, Mathieu Roule, Jean-Baptiste Fouvry +2
We present LinearResponse.jl, an efficient, versatile public library written in julia to compute the linear response of self-gravitating (3D spherically symmetric) stellar spheres…
Non-resonant relaxation of anisotropic globular clusters
Kerwann Tep, Jean-Baptiste Fouvry, Christophe Pichon
Globular clusters are dense stellar systems whose core slowly contracts under the effect of self-gravity. The rate of this process was recently found to be directly linked to the i…
The NewHorizon Simulation -- To Bar Or Not To Bar
J. Reddish, K. Kraljic, M. S. Petersen +12
We use the NewHorizon simulation to study the redshift evolution of bar properties and fractions within galaxies in the stellar masses range $M_{\star} = 10^{7.25} - 10^{11.4} \ \r…
Mapping the Galactic centre's dark cluster via Resonant Relaxation
Kerwann Tep, Jean-Baptiste Fouvry, Christophe Pichon +4
Supermassive black holes in the centre of galaxies dominate the gravitational potential of their surrounding stellar clusters. In these dense environments, stars follow nearly Kepl…
