The dwarf irregular galaxy NGC 6822. II. Young, intermediate and old stellar populations: comparison between theory and observations
Maria Tantalo, Giuseppe Bono, Maurizio Salaris +14
This paper presents a quantitative analysis of the stellar content in the Local Group dwarf irregular galaxy NGC 6822 by comparing stellar evolution models and observations in colo…
The elderly among the oldest: new evidence for extremely metal-poor RR Lyrae stars
Valentina D'Orazi, Vittorio F. Braga, Giuseppe Bono +21
We performed a detailed spectroscopic analysis of three extremely metal-poor RR Lyrae stars, exploring uncharted territories at these low metallicities for this class of stars. Usi…
Benchmarking the effective temperature scale of red giant branch stellar models: the case of the metal-poor halo giant HD 122563
O. L. Creevey, S. Cassisi, F. Thévenin +2
There is plenty of evidence in the literature of significant discrepancies between the observations and models of metal-poor red giant branch stars, in particular regarding the eff…
Classical Cepheid Pulsation properties in the Rubin-LSST filters
Giulia De Somma, Marcella Marconi, Santi Cassisi +8
Homogeneous multi-wavelength observations of classical Cepheids from the forthcoming Rubin-LSST have the potential to significantly contribute to our understanding of the evolution…
Double Red Giant Branch and Red Clump features of Galactic disc stellar populations with Gaia GSPspec
Alejandra Recio-Blanco, P. de Laverny, P. A. Palicio +4
To disentangle the different competing physical processes at play in Galactic evolution, a detailed chrono chemicalkinematical, and dynamical characterisation of the disc bimodalit…
The updated BaSTI stellar evolution models and isochrones.IV. alpha-depleted calculations
Adriano Pietrinferni, Maurizio Salaris, Santi Cassisi +4
This is the fourth paper of our new release of the BaSTI (a Bag of Stellar Tracks and Isochrones) stellar model and isochrone library. Following the updated solar-scaled, alpha-enh…
