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 IV. Unveiling extreme element production: the Eu abundance in the Small Magellanic Cloud
Samuele Anoardo, Alessio Mucciarelli, Marco Palla +3
In this study we investigate the chemical enrichment of the rapid neutron-capture process in the Small Magellanic Cloud (SMC). We measure [Eu/Fe] abundance ratios in 209 giant star…
Dynamical mirages: how bar-induced resonant trapping can mimic substructure clustering in dynamical parameter spaces
Michele De Leo, Davide Massari, Michele Bellazzini +3
The complex task of unraveling the assembly history of the Milky Way is in constant evolution with new substructures identified continuously. To properly validate and characterise…
A Walk on the Retrograde Side (WRS) project. II. Chemistry to disentangle in situ and accreted components in Thamnos
E. Ceccarelli, D. Massari, M. Palla +3
We present the results of the first systematic and dedicated high-resolution chemical analysis of the Thamnos substructure, a candidate relic of the process of hierarchical merger…
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…
Lithium evolution in the Galactic thin disc from Main-Sequence and early Red-Giant-Branch stars
C. T. Nguyen, G. Cescutti, F. Matteucci +7
The role of novae as producers of galactic lithium has been suggested since the 1970s, and it has been reconsidered recently with the detection of Be in their outbursts. At the…
Cluster Ages to Reconstruct the Milky Way Assembly (CARMA) IV. Chrono-dynamics of seven old star clusters in the Large Magellanic Cloud and the peculiar origin of NGC 1841
F. Niederhofer, D. Massari, F. Aguado-Agelet +15
In this study, we report conclusive evidence for an ancient star cluster that has been accreted by the Large Magellanic Cloud (LMC). By leveraging observations from the Hubble Spac…
Cosmic Threads: Interlinking the Stellar Initial Mass Function from Star-Birth to Galaxies
Tereza Jerabkova, Donatella Romano, Pavel Kroupa +19
The stellar initial mass function (sIMF) describes the distribution of stellar masses formed in a single star formation event in a molecular cloud clump. It is fundamental to astro…
New kinematic map of the Milky Way bulge
Carlos Quezada, Manuela Zoccali, Elena Valenti +7
The kinematics of the Milky Way bulge is known to be complex, reflecting the presence of multiple stellar components with distinct chemical and spatial properties. In particular, t…
Detection of a white dwarf orbiting a Carbon-Oxygen depleted blue straggler in 47 Tucanae

We have employed deep far-UV observations secured with the Solar Blind Channel of the Advanced Camera for Surveys onboard the Hubble Space Telescope to search for hot companions to…
Inferring the efficiency of convective-envelope overshooting in Red Giant Branch stars
Lorenzo Briganti, Marco Tailo, Edoardo Ceccarelli +6
The understanding of mixing processes in stars is crucial for improving our knowledge of the chemical abundances in stellar photospheres and of their variation with evolutionary ph…
