Long-term evolution of multimass rotating star clusters
Alexander R. Livernois, Enrico Vesperini, Anna Lisa Varri +2
We investigate the long-term dynamical evolution of the internal kinematics of multimass rotating star clusters. We have performed a set of N-body simulations to follow the interna…
The ESO-VLT MIKiS survey reloaded: velocity dispersion profile and rotation curve of NGC 1904
S. Leanza, C. Pallanca, F. R. Ferraro +8
We present an investigation of the internal kinematic properties of M79 (NGC 1904). Our study is based on radial velocity measurements obtained from the ESO-VLT Multi-Instrument Ki…
Early dynamical evolution of rotating star clusters in a tidal field
Maria Tiongco, Enrico Vesperini, Anna Lisa Varri
In order to explore how the early internal rotational properties of star clusters are affected by the external potential of their host galaxies, we have run a suite of -body sim…
Early dynamics and violent relaxation of multi-mass rotating star clusters
A. R. Livernois, E. Vesperini, M. Tiongco +2
We present the results of a study aimed at exploring, by means of N-body simulations, the evolution of rotating multi-mass star clusters during the violent relaxation phase, in the…
Central Dynamics of Multi-mass Rotating Star Clusters
Maria Tiongco, Angela Collier, Anna Lisa Varri
We investigate the evolutionary nexus between the morphology and internal kinematics of the central regions of collisional, rotating, multi-mass stellar systems, with special atten…
A Lopsided Outer Solar System
Alexander Zderic, Maria Tiongco, Angela Collier +3
Axisymmetric disks of eccentric orbits in near-Keplerian potentials are unstable to an out-of-plane buckling. Recently, Zderic et al. (2020) showed that an idealized disk saturates…
First phase space portrait of a hierarchical stellar structure in the Milky Way
E. Dalessandro, A. L. Varri, M. Tiongco +10
We present the first detailed observational picture of a possible ongoing massive cluster hierarchical assembly in the Galactic disk as revealed by the analysis of the stellar full…
Apsidal Clustering following the Inclination Instability
Alexander Zderic, Angela Collier, Maria Tiongco +1
Disks of low-mass bodies on high-eccentricity orbits in near-Keplerian potentials can be dynamically unstable to buckling out of the plane. In this letter, we present -body simu…
Kinematical evolution of multiple stellar populations in star clusters
Maria Tiongco, Enrico Vesperini, Anna Lisa Varri
We present the results of a suite of \Nbody simulations aimed at understanding the fundamental aspects of the long-term evolution of the internal kinematics of multiple stellar pop…
The strong rotation of M5 (NGC 5904) as seen from the MIKiS Survey of Galactic Globular Clusters
B. Lanzoni, F. R. Ferraro, A. Mucciarelli +10
In the context of the ESO-VLT Multi-Instrument Kinematic Survey (MIKiS) of Galactic globular clusters, we present the line-of-sight rotation curve and velocity dispersion profile o…
The complex kinematics of rotating star clusters in a tidal field
Maria Tiongco, Enrico Vesperini, Anna Lisa Varri
We broaden the investigation of the dynamical properties of tidally perturbed, rotating star clusters by relaxing the traditional assumptions of coplanarity, alignment, and synchro…
Kinematical evolution of tidally limited star clusters: rotational properties
Maria A. Tiongco, Enrico Vesperini, Anna Lisa Varri
We present the results of a set of N-body simulations following the long-term evolution of the rotational properties of star cluster models evolving in the external tidal field of…
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…
Velocity anisotropy in tidally limited star clusters
Maria Tiongco, Enrico Vesperini, Anna Lisa Varri
We explore the long-term evolution of the anisotropy in the velocity space of star clusters starting with different structural and kinematical properties. We show that the evolutio…
