Journal ArticleDOI
Rotating Globular Clusters
TL;DR: In this article, the authors present a dynamical analysis of the photometry and three-dimensional kinematics of ω Cen, 47 Tuc, and M15, by means of a recently introduced family of self-consistent axisymmetric rotating models.
Journal ArticleDOI
A novel look at energy equipartition in globular clusters
TL;DR: In this paper, the stellar mass dependence of the velocity dispersion σ(m) can be described by an exponential function σ 2 ∝ exp(−m/meq), with the parameter σ 1 −m −meq quantifying the degree of partial energy equipartition of the systems.
Journal ArticleDOI
MIKiS: The Multi-instrument Kinematic Survey of Galactic Globular Clusters. I. Velocity Dispersion Profiles and Rotation Signals of 11 Globular Clusters
Francesco R. Ferraro,Alessio Mucciarelli,Barbara Lanzoni,C. Pallanca,E. Lapenna,Livia Origlia,Emanuele Dalessandro,Elena Valenti,Giacomo Beccari,Michele Bellazzini,Enrico Vesperini,Anna Lisa Varri,Antonio Sollima +12 more
TL;DR: The first results of the Multi-Instrument Kinematic Survey of Galactic Globular Clusters (MKCS) as mentioned in this paper, a project aimed at exploring the internal kinematics of a representative sample of Galactic globular clusters from the radial velocity of individual stars, covering the entire radial extension of each system.
Journal ArticleDOI
Hubble Space Telescope Proper Motion (HSTPROMO) Catalogs of Galactic Globular Clusters. V. The Rapid Rotation of 47 Tuc Traced and Modeled in Three Dimensions
Andrea Bellini,Paolo Bianchini,Anna Lisa Varri,Jonathan Anderson,Giampaolo Piotto,R. P. van der Marel,Enrico Vesperini,Laura L. Watkins +7 more
TL;DR: In this article, high-precision proper motions of the globular cluster 47 Tuc have allowed the first time the cluster rotation in the plane of the sky and the velocity anisotropy profile from the cluster core out to about 13'.
Journal ArticleDOI
Velocity anisotropy in tidally limited star clusters
TL;DR: In this paper, the authors explore the long-term evolution of the radial anisotropy in the velocity space of star clusters starting with different structural and kinematical properties.
