Kinematics of Multiple Stellar Populations in Globular Clusters with
  Gaia
  The internal dynamics of multiple stellar populations in Globular Clusters
(GCs) provides unique constraints on the physical processes responsible for
their formation. Specifically, the present-day kinematics of cluster stars,
such as rotation and velocity dispersion, seems to be related to the initial
configuration of the system. In recent work (Milone et al. 2018), we analyzed
for the first time the kinematics of the different stellar populations in
NGC0104 (47Tucanae) over a large field of view, exploiting the Gaia Data
Release 2 proper motions combined with multi-band ground-based photometry. In
this paper, based on the work by Cordoni et al. (2019), we extend this analysis
to six GCs, namely NGC0288, NGC5904 (M5), NGC6121 (M4), NGC6752, NGC6838 (M71)
and further explore NGC0104. Among the analyzed clusters only NGC0104 and
NGC5904 show significant rotation on the plane of the sky. Interestingly,
multiple stellar populations in NGC5904 exhibit different rotation curves.
