The variable mass-loss in low-mass red giant stars: Chromospheric motion across stellar evolution in 47 Tuc
Ian Baeza, L. Monaco, H. Frelijj +8
Mass-Loss (ML) is a critical process that remains poorly understood despite its broad implications across astrophysics. Our current knowledge is insufficient to reproduce ML consis…
Beryllium enhancement in stars of the accreted Thamnos-2 system
Paolo Molaro, Piercarlo Bonifacio, Elisabetta Caffau +2
Surveys of Galactic halo stars have revealed numerous streams and substructures tracing stellar populations accreted by the Milky Way. Among these, Gaia-Sausage-Enceladus (GSE) and…
Abundances of CNO in candidate young metal-poor stars
Piercarlo Bonifacio, Elisabetta Caffau, Luca Sbordone +6
In this contribution we investigate the CNO abundances in five apparently young evolved stars, with the aim of discriminating between truly young stars and stars that were rejuvena…
The chemical DNA of the Magellanic Clouds V. R-process dominates neutron capture elements production in the oldest SMC stars
Lorenzo Santarelli, Marco Palla, Alessio Mucciarelli +4
We present the chemical abundances of Fe, alpha- and neutron-capture elements in 12 metal-poor Small Magellanic Cloud (SMC) giant stars, observed with the high-resolution spectrogr…
Fast Rotating Blue Straggler Stars in the globular cluster NGC 1851
Alex Billi, Lorenzo Monaco, Francesco R. Ferraro +4
In this work we study the rotational velocities of a sample of blue straggler stars (BSSs) and reference stars belonging to the Galactic globular cluster NGC 1851, using high-resol…
The chemical DNA of the Magellanic Clouds III. The first, extragalactic Mg-K anticorrelation: the LMC globular cluster NGC 1786
Deimer Antonio Alvarez Garay, Alessio Mucciarelli, Lorenzo Monaco
In this work we derived [K/Fe] and [Mg/Fe] abundance ratios for six stars of the old globular cluster NGC 1786 in the Large Magellanic Cloud. We employed high-resolution spectra ac…
