SDSS-V LVM: A spatially resolved study of the physical conditions and the chemical abundance discrepancy in the Lagoon Nebula (M 8)
Amrita Singh, Guillermo A. Blanc, Nimisha Kumari +19
The abundance discrepancy problem refers to the systematic differences observed between chemical abundances derived from collisionally excited lines (CELs) and recombination lines…
Kinematical and dynamical properties of recently discovered bulge and disc star clusters with WINERED
Ilaria Petralia, Dante Minniti, José G. Fernández-Trincado +8
Context. Galactic globular clusters are a very important tool in explaining the characteristics of the Milky Way. Therefore it is essential to determine the kinematical and dynamic…
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…
Is Liller 1 a building block of the Galactic bulge? -- Evidence with APOGEE
Anna Liptrott, Ricardo P. Schiavon, Andrew C. Mason +10
Liller 1 is a stellar system orbiting within the inner 0.8kpc of the Galactic centre, characterised by a wide spread in age and metallicity, indicating a high mass. Liller 1 has be…
Investigating Phosphorus Abundances in a Sample of APOGEE-2 Bulge Globular Clusters
Beatriz Barbuy, José G. Fernández-Trincado, Morgan S. Camargo +9
Phosphorus enhanced (P-rich; [P/Fe] > 0.8) giants have been found among mildly metal-poor fiels stars, but in only one star in a globular cluster (GC), M4 (NGC 6121). Also, in a sa…
CAPOS: The bulge Cluster APOgee Survey VIII. Final ASPCAP results for all clusters
Doug Geisler, Cesar Muñoz, Sandro Villanova +12
Bulge globular clusters(BGCs) are exceptional tracers of the formation and chemodynamical evolution of this oldest Galactic component. However, until now, observational difficultie…
