Phosphorous in the moderately metal-poor bulge globular clusters NGC 6539 and NGC 6569

Morgan S. Camargo, Beatriz Barbuy, Heitor Ernandes +10

The distinct stellar populations of the Galactic bulge can be disentangled through detailed analysis of their chemical abundances and kinematical properties. Recent studies have su…

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…

Spectroscopic analysis of RGB stars in nine open clusters

Saulo de Oliveira Cantanhêde, Alan Alves-Brito, Rodolfo Smiljanic +4

Stellar clusters are crucial tools for studying the age, spatial distribution, dynamics, kinematics, and chemical composition of different Galactic stellar populations. In this wor…

Chemical radial gradients for the bulge-bar stellar populations from the APOGEE survey

J. V. Sales-Silva, K. Cunha, V. V. Smith +20

The Milky Way bulge-bar is composed of multiple populations. Using chemical and kinematical planes, we segregate six populations in a bulge-bar sample observed by the APOGEE survey…

A Tale of Two Origins: In-Situ versus Accreted Nitrogen-Rich Field Stars in the MW

Yi Qiao, Baitian Tang, José G. Fernández-Trincado +14

Spectroscopic surveys have identified significant numbers of metal-poor nitrogen-rich (N-rich) field stars. These stars are strong candidates for escapees from globular clusters (G…

HST+IGRINS synergy to characterise the newly discovered metal-rich bulge globular cluster Patchick 126

Elisa R. Garro, Davide Massari, José G. Fernández-Trincado +10

We present the first comprehensive spectroscopic and deep photometric study of the globular cluster (GC) candidate Patchick~126. The spectroscopic analysis is based on high-resolut…
