Stellar ages from [C/N] in giant stars: applicability and limitations
Giada Casali, Luca Casagrande, Fiorenzo Vincenzo +5
The [C/N] abundance ratio is a powerful age indicator for giant stars, enabling age estimates for spectroscopic samples where traditional methods are limited. We calibrate a multiv…
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…
Not all nitrogen-rich field stars originate from globular clusters
Ellen I. Leitinger, Andrea Miglio, Josefina Montalbán +7
Globular clusters (GCs) are important tracers of the early Galactic assembly process, with part of their stars showing distinct chemical abundance patterns. When such stars are fou…
Predictions of gravity mode pulsations of collisional blue straggler stars in globular clusters
Lorenzo Briganti, Walter Eduard van Rossem, Andrea Miglio +2
Blue straggler stars (BSSs) are exotic objects, which, being the results of processes such as mass transfer, mergers, or collisions, are considered key objects in the study of thei…
The impact of rotational mixing in intermediate-age star clusters with extended main-sequence turn-offs and extended red clumps
Lorenzo Martinelli, Andrea Miglio, Gaël Buldgen +6
The extended main-sequence turn-offs (eMSTOs) and extended red clumps (eRCs) observed in intermediate-age star clusters challenge the traditional understanding of clusters as simpl…
Parametric models of core-helium-burning stars: structural glitches near the core
Massimiliano Matteuzzi, Gaël Buldgen, Marc-Antoine Dupret +3
Understanding the internal structure of core helium burning (CHeB) stars is crucial for evaluating transport processes in nuclear-burning regions, constructing accurate stellar pop…
