Local Group and Star Cluster Dynamics from HSTPROMO (The Hubble Space Telescope Proper Motion Collaboration)
Roeland P. van der Marel, Jay Anderson, Andrea Bellini +17
The Hubble Space Telescope (HST) has proven to be uniquely suited for the measurement of proper motions (PMs) of stars and galaxies in the nearby Universe. Here we summarize the ma…
Rotating Globular Clusters
P. Bianchini, A. L Varri, G. Bertin +1
Internal rotation is considered to play a major role in the dynamics of some globular clusters. However, in only few cases it has been studied by quantitative application of realis…
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…
