CRIMSONS: An Online Tool for Modeling Chemical Enrichment with Stochastic IMF Sampling
Martina Rossi, Lapo Querci, Stefano Ciabattini +14
Chemical enrichment is a universal process shaped by several interconnected factors, including stellar feedback, the nature of chemical polluters, and the underlying distribution o…
Tracing Stellar Populations through the Mg-Al Anti-Correlation in Gaia-ESO Globular Clusters
H. Sinclair-Wentworth, C. C. Worley, P. Jofre +2
Context. Globular clusters (GCs) are fragments of the chemical history and evolution of the Milky Way. Their notable intra-cluster abundance variations have been used to characteri…
WST instrument Exposure Time Calculator: full simulation of multi-mode spectrograph performance from source to detector
Matteo Ferro, Matteo Genoni, Henri M. J. Boffin +13
We present a comprehensive Exposure Time Calculator (ETC) developed for the Wide-field Spectroscopic Telescope (WST) concept. The WST, currently in its conceptual phase, is designe…
Intrinsic iron abundance spreads in globular clusters
J. Schiappacasse-Ulloa, S. Lucatello, L. Magrini +2
Globular Clusters (GCs) host multiple stellar populations, likely composed of a subset of FG stars that enriched the intracluster medium and gave rise to SG stars, each characteris…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
Tracing the Early Milky Way with Globular Clusters: The Diagnostic Power of Neutron-Capture Elements
J. Schiappacasse-Ulloa, L. Berni, S. Lucatello +3
Globular clusters (GCs) are fundamental tracers of the early assembly of the Milky Way (MW). They formed in diverse environments -- including both our Galaxy and dwarf galaxies --…
Barium isotopic ratios in metal-poor stars: calibrating the method with globular clusters
Riano E. Giribaldi, Laura Magrini, Jose Schiappacasse-Ulloa +2
Identifying the nucleosynthesis processes behind heavy-element enrichment in stellar atmospheres is challenging. It typically relies on comparing observed abundance-to-iron ratios…
Neutron-Capture Element Signatures in Globular Clusters: Insights from the Gaia-ESO Survey
J. Schiappacasse-Ulloa, L. Magrini, S. Lucatello +8
Globular clusters (GCs) are key to understanding the formation and evolution of our Galaxy. While the abundances of light and Fe-peak elements in GCs have been widely studied, inve…
Heavy element abundances in Galactic Globular Clusters
J. Schiappacasse-Ulloa, S. Lucatello, G. Cescutti +1
Context. Globular clusters are considered key objects for understanding the formation and evolution of the Milky Way. In this sense, their characterisation in terms of their chemic…
Parameter Estimation for Open Clusters using an Artificial Neural Network with a QuadTree-based Feature Extractor
L. Cavallo, L. Spina, G. Carraro +7
With the unprecedented increase of known star clusters, quick and modern tools are needed for their analysis. In this work, we develop an artificial neural network trained on synth…
Quadtree features for machine learning on CMDs
Jose Schiappacasse-Ulloa, Mario Pasquato, Sara Lucatello
The upcoming facilities like the Vera C. Rubin Observatory will provide extremely deep photometry of thousands of star clusters to the edge of the Galaxy and beyond, which will req…
Neutron-capture elements in NGC 6752 multiple populations
J. Schiappacasse-Ulloa, S. Lucatello
Globular clusters have been widely studied in terms of light element variations present in their different stellar populations. However, the nature of the polluter(s) responsible f…
Lithium abundances as a tracer of AGB stars pollution in the globular cluster NGC 6752
J. Schiappacasse-Ulloa, S. Lucatello, M. J. Rain +1
This paper presents the chemical abundance analysis of 217 stars in the metal-poor globular cluster NGC 6752, distributed from the turn-off to the lower red giant branch. Aluminium…
A chemical and kinematical analysis of the intermediate-age open cluster IC 166 from APOGEE and Gaia DR2
J. Schiappacasse-Ulloa, B. Tang, J. G. Fernández-Trincado +26
IC 166 is an intermediate-age open cluster ( Gyr) which lies in the transition zone of the metallicity gradient in the outer disc. Its location, combined with our very limi…
