Stellar population astrophysics (SPA) with the TNG. Characterization of the young open cluster ASCC 123
A. Frasca, J. Alonso-Santiago, G. Catanzaro +10
Star clusters are key to understand the stellar and Galactic evolution. ASCC 123 is a little-studied, nearby and very sparse open cluster. We performed the first high-resolution sp…
The Gaia-ESO Survey: The inner disc, intermediate-age open cluster Pismis 18
D. Hatzidimitriou, E. V. Held, E. Tognelli +34
Pismis 18 is a moderately populated, intermediate-age open cluster located within the solar circle at a Galactocentric distance of about 7 kpc. Few open clusters have been studied…
Open clusters in APOGEE and GALAH: Combining Gaia and ground-based spectroscopic surveys
R. Carrera, A. Bragaglia, T. Cantat-Gaudin +7
Context: Open clusters are ideal laboratories to investigate a variety of astrophysical topics, from the properties of the Galactic disk to stellar evolutionary models. Knowing the…
Age determination for 269 DR2 Open Clusters
D. Bossini, A. Vallenari, A. Bragaglia +9
. Gaia Second Data Release provides precise astrometry and photometry for more than 1.3 billion sources. This catalog opens a new era concerning the characterization of op…
