A 3D view of multiple populations kinematics in Galactic globular clusters
E. Dalessandro, M. Cadelano, A. Della Croce +8
We present the first 3D kinematic analysis of multiple stellar populations (MPs) in a representative sample of 16 Galactic globular clusters (GCs). For each GC in the sample we stu…
Rotational velocities of Blue Straggler Stars in the Globular Cluster M55
Alex Billi, Francesco R. Ferraro, Alessio Mucciarelli +3
By using high-resolution spectra acquired with FLAMES-GIRAFFE at the ESO/VLT, we measured radial and rotational velocities of 115 stars in the Galactic globular cluster M55. After…
The ESO-VLT MIKiS survey reloaded: the internal kinematics of the core of M75
Silvia Leanza, Cristina Pallanca, Francesco R. Ferraro +7
We present the results of a study aimed at characterizing the kinematics of the inner regions of the halo globular cluster M75 (NGC 6864) based on data acquired as part of the ESO-…
The dynamical age of the LMC globular cluster NGC 1835 using the "dynamical clock"
Camilla Giusti, Mario Cadelano, Francesco R. Ferraro +5
In the context of the study of the size-age relationship observed in star clusters in the Large Magellanic Cloud and the investigation of its origin, here we present the determinat…
Discovery of an extended Horizontal Branch in the Large Magellanic Cloud globular cluster NGC1835
Camilla Giusti, Mario Cadelano, Francesco R. Ferraro +6
We present a high angular resolution multi-wavelength study of the massive globular cluster NGC 1835 in the Large Magellanic Cloud. Thanks to a combination of optical and near ultr…
The structural properties of multiple populations in globular clusters: the instructive case of NGC 3201
Mario Cadelano, Emanuele Dalessandro, Enrico Vesperini
All multiple population (MP) formation models in globular clusters (GCs) predict that second population (SP) stars form more centrally concentrated than the first population (FP).…
