Investigating the population of Galactic star formation regions and star clusters within a Wide-Fast-Deep Coverage of the Galactic Plane
L. Prisinzano, L. Magrini, F. Damiani +32
One of the aims of LSST is to perform a systematic survey of star clusters and star forming regions (SFRs) in our Galaxy. In particular, the observations obtained with LSST will ma…
Expanding associations in the Vela-Puppis region: 3D structure and kinematics of the young population
T. Cantat-Gaudin, C. Jordi, N. J. Wright +9
The Vela-Puppis region is known to host the Vela OB2 association as well as several young clusters featuring OB and pre-main sequence stars. Several spatial and kinematic subgroups…
Masses and ages for metal-poor stars: a pilot program combining asteroseismology and high-resolution spectroscopic follow-up of RAVE halo stars
M. Valentini, C. Chiappini, D. Bossini +10
Very metal-poor halo stars are the best candidates for being among the oldest objects in our Galaxy. Samples of halo stars with age determination and detailed chemical composition…
Open cluster kinematics with Gaia DR2
C. Soubiran, T. Cantat-Gaudin, M. Romero-Gómez +16
Context. Open clusters are very good tracers of the evolution of the Galactic disc. Thanks to Gaia, their kinematics can be investigated with an unprecedented precision and accurac…
A ring in a shell: the large-scale 6D structure of the Vela OB2 complex
T. Cantat-Gaudin, M. Mapelli, L. Balaguer-Núñez +3
The Vela OB2 association is a group of 10 Myr stars exhibiting a complex spatial and kinematic substructure. The all-sky Gaia DR2 catalogue contains proper motions, parallaxes (a p…
The Gaia-ESO Survey: the N/O abundance ratio in the Milky Way
L. Magrini, F. Vincenzo, S. Randich +31
The abundance ratio N/O is a useful tool to study the interplay of galactic processes, e.g. star formation efficiency, time-scale of infall and outflow loading factor We aim to tra…
