Kinematical evolution of tidally limited star clusters: the role of retrograde stellar orbits
Maria Tiongco, Enrico Vesperini, Anna Lisa Varri
The presence of an external tidal field often induces significant dynamical evolutionary effects on the internal kinematics of star clusters. Previous studies investigating the res…
A novel look at energy equipartition in globular clusters
P. Bianchini, G. van de Ven, M. A. Norris +2
Two-body interactions play a major role in shaping the structural and dynamical properties of globular clusters (GCs) over their long-term evolution. In particular, GCs evolve towa…
Biases in the determination of dynamical parameters of star clusters: today and in the Gaia era
A. Sollima, H. Baumgardt, A. Zocchi +4
The structural and dynamical properties of star clusters are generally derived by means of the comparison between steady-state analytic models and the available observables. With t…
Neutron star natal kicks and the long-term survival of star clusters
Filippo Contenta, Anna Lisa Varri, Douglas C. Heggie
We investigate the dynamical evolution of a star cluster in an external tidal field by using N-body simulations, with focus on the effects of the presence or absence of neutron sta…
The flattening of globular clusters: internal rotation or velocity anisotropy?
Paolo Bianchini, Anna Lisa Varri, Giuseppe Bertin +1
Internal rotation is considered to play a major role in determining the structure and dynamics of some globular clusters. We present a dynamical analysis of the photometry and thre…
The construction of non-spherical models of quasi-relaxed stellar systems
G. Bertin, A. L. Varri
Spherical models of collisionless but quasi-relaxed stellar systems have long been studied as a natural framework for the description of globular clusters. Here we consider the con…
