Dynamical Signatures of Trumpler 19: A Statistical and Photometric Perspective

The Astrophysical Journal
We present a statistical approach to investigating the dynamical evolution of the old open cluster Trumpler 19. We identified 810 cluster members using an ensemble-based unsupervised machine learning method applied to Gaia Data Release 3 astrometric data.

Rotational velocities of blue straggler stars in the globular cluster M 55

Astronomy & Astrophysics
By using high-resolution spectra acquired with FLAMES-GIRAFFE at the ESO/VLT, we measured the radial and rotational velocities of 115 stars in the Galactic globular cluster M 55. After field decontamination based on the radial velocity values, the final sample of member stars is composed of 32 blue straggler stars (BSSs) and 76 reference stars ...
