The role of mass transfer efficiency in stability criteria: Implementation in SEVN and a test on blue stragglers and binary compact objects
M. Echeveste, G. J. Escobar, G. Iorio +12
Context: The stability of mass transfer through Roche-lobe overflow plays a key role in shaping the outcome of binary interactions. However, the criterion for mass transfer stabili…
Stellar rotation and binaries in open clusters with Gaia DR3
Elena Pancino, Elisabetta Reggiani, Silvia Marinoni +14
Stellar rotation is a fundamental ingredient in shaping the evolution of stars and it can also be used to trace past stellar interactions. Yet, systematic studies of stellar rotati…
MgAl burning chain in M 54: the globular cluster-like properties of a nuclear star cluster
D. A. Alvarez Garay, A. Mucciarelli, P. Ventura +2
In this study, we present the chemical abundances of Fe, Mg, Al, Si, and K for a sample of 233 likely member stars of M 54. All the stars were observed with the FLAMES high-resolut…
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…
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…
Survey of Surveys. II. Stellar parameters for 23 millions of stars
A. Turchi, E. Pancino, A. Avdeeva +16
In the current panorama of large surveys, the vast amount of data obtained with different methods, data types, formats, and stellar samples, is making an efficient use of the avail…
