The potential broader complex linked to the key Cepheid SV Vul
Daniel Majaess, Ignacio Negueruela, Leonid N. Berdnikov +10
A new distance was established to the Cepheid SV Vul () and its host cluster Alicante 13, and is tied in part to deeper UKIDSS-DR6 photometry and Gaia DR3 observatio…
Age Determination of LAMOST Red Giant Branch stars based on the Gradient Boosting Decision Tree method
Hai-Feng Wang, Giovanni Carraro, Xin Li +5
In this study we estimate the stellar ages of LAMOST DR8 Red Giant Branch (RGB) stars based on the Gradient Boosting Decision Tree algorithm (GBDT). We used 2,643 RGB stars extract…
The Gaia-ESO Survey: Calibrating the lithium-age relation with open clusters and associations. I. Cluster age range and initial membership selections
M. L. Gutiérrez Albarrán, D. Montes, M. Gómez Garrido +33
Previous studies of open clusters have shown that lithium depletion is not only strongly age dependent but also shows a complex pattern with other parameters that is not yet unders…
Chemical abundance analysis of red giant branch stars in the globular cluster E3
L. Monaco, S. Villanova, G. Carraro +2
Context. Globular clusters are known to host multiple stellar populations, which are a signature of their formation process. The globular cluster E3 is one of the few low-mass glob…
The Gaia-ESO survey: impact of extra-mixing on C- and N-abundances of giant stars
N. Lagarde, C. Reylé, A. C. Robin +30
The GES survey using FLAMES at the VLT has obtained high-resolution UVES spectra for a large number of giant stars, allowing a determination of the abundances of the key chemical e…
Stellar populations in the Carina region: The Galactic plane at l = 291
J. A. Molina-Lera, G. Baume, R. Gamen +2
Previous studies of the Carina region have revealed its complexity and richness as well as a significant number of early-type stars. In many cases, these studies only concentrated…
