Low mass young stars in the Milky Way unveiled by DBSCAN and Gaia EDR3. Mapping the star forming regions within 1.5 Kpc
L. Prisinzano, F. Damiani, S. Sciortino +6
With an unprecedented astrometric and photometric data precision, Gaia EDR3 gives us, for the first time, the opportunity to systematically detect and map in the optical bands, the…
Robust statistical tools for identifying multiple stellar populations in globular clusters in the presence of measurement errors. A case study: NGC 2808
G. Valle, M. Dell'Omodarme, E. Tognelli
The finding of multiple stellar populations (MP), defined by patterns in the stellar element abundances, is nowadays considered a distinctive feature of globular clusters. However,…
Bayesian calibration of the mixing length parameter and of the helium-to-metal enrichment ratio with open clusters: the Hyades test-bed
E. Tognelli, M. Dell'Omodarme, G. Valle +2
We tested the capability of a Bayesian procedure to calibrate both the helium abundance and the mixing length parameter (), using precise photometric data for main-sequence…
The Gaia-ESO survey: Calibrating a relationship between Age and the [C/N] abundance ratio with open clusters
G. Casali, L. Magrini, E. Tognelli +51
In the era of large high-resolution spectroscopic surveys, high-quality spectra can contribute to our understanding of the Galactic chemical evolution, providing chemical abundance…
Deep near-infrared imaging of W3 Main: constraints on stellar cluster formation
A. Bik, A. Stolte, M. Gennaro +10
Embedded clusters like W3 Main are complex and dynamically evolving systems that represent an important phase of the star formation process. We aim at the characterization of the e…
Instantaneous starburst of the massive clusters Westerlund 1 and NGC 3603 YC
Natalia Kudryavtseva, Wolfgang Brandner, Mario Gennaro +9
We present a new method to determine the age spread of resolved stellar populations in a starburst cluster. The method relies on a two-step process. In the first step, kinematic me…
