ROLLIN': Rotating globular cluster simulations II. The complex morphology of globular clusters driven by multi-scale dynamics

Arn Marklund, Paolo Bianchini, Anna Lisa Varri +2

Globular clusters (GCs) are inherently non-spherical systems that in many cases show internal rotation. Typically, rotation is considered the main driver of GC morphology; however,…

The stability of radially anisotropic rotating stellar systems with a central density cusp

Pierfrancesco Di Cintio, Anna Lisa Varri

We investigate the interplay between radial velocity anisotropy and internal rotation in self-gravitating systems characterised by initial spherical symmetry and a moderate density…

Disruption of a Giant: Spectroscopic Identification of Members in the Periphery and Tidal Tails of Centauri

P. B. Kuzma, A. M. N. Ferguson, A. L. Varri +1

Centauri ( Cen, NGC\,5139) is one of the most enigmatic globular clusters in the Milky Way, with the recent detection of tidal tails adding further to its complexity. We r…

Tidally Perturbed, Rotating Stellar Systems: Asynchronous Equilibria

Lucy A. Z. Arditi, Anna Lisa Varri

We present a new three-parameter family of self-consistent equilibrium models for quasi-relaxed stellar systems that are subject to the combined action of external tides and rigid…

Evolution of the kinematic properties of rotating multiple-population globular clusters

Ethan B. White, Enrico Vesperini, Emanuele Dalessandro +1

Globular clusters (GCs) host multiple stellar populations differing in their chemical and dynamical properties. A number of models for the formation of multiple populations predict…
