Mergers, tidal interactions, and mass exchange in a population of disc globular clusters: II. Long-term evolution
Alessandra Mastrobuono-Battisti, Sergey Khoperskov, Paola Di Matteo +1
Globular clusters (GCs), the oldest stellar systems observed in the Milky Way, have for long been considered single stellar populations. As such, they provided an ideal laboratory…
Mergers, tidal interactions, and mass exchange in a population of disc globular clusters
Sergey Khoperskov, Alessandra Mastrobuono-Battisti, Paola Di Matteo +1
We present the results of a self-consistent -body simulation following the evolution of a primordial population of thick disc globular clusters (GCs). We study how the internal…
Gaia Data Release 2. Summary of the contents and survey properties
Gaia Collaboration, A. G. A. Brown, A. Vallenari +4
We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources…
The disc origin of the Milky Way bulge
P. Di Matteo
The Galactic bulge, that is the prominent out-of-plane over-density present in the inner few kiloparsecs of the Galaxy, is a complex structure, as the morphology, kinematics, chemi…
