Reassessing the low- massive sequence stars in Gaia RVS
G. Nandakumar, G. Kordopatis, M. Schultheis +4
Recently, a chemically depleted young massive stellar population was identified using the spectroscopic catalogue of Gaia DR3. To explain its characteristics, a recent enhanced sta…
Chemical analysis of the Milky Way's Nuclear Star Cluster: Evidence for a metallicity gradient
M. Schultheis, L. Serrano, B. Thorsbro +5
The Milky Way nuclear star cluster (MWNSC) is located together with its surrounding nuclear stellar disc (MWNSD) in the Galactic centre and they dominate the gravitational potentia…
Supergiant GCIRS 22 in the Milky Way Nuclear Star Cluster: Revised alpha abundances
B. Thorsbro, S. Khalidy, R. M. Rich +7
Context: The chemical abundances of alpha-elements in Galactic Centre (GC) supergiants provide key insights into the chemical enrichment and star formation history of the Milky Way…
Rubidium Abundances in Cool Giants from High-Resolution H-band Spectra: A New Diagnostic for Galactic Chemical Evolution
Nils Ryde, Jess Kocher, Govind Nandakumar +6
The Galactic Center and inner disk of the Milky Way contain complex stellar populations obscured by heavy dust extinction. To study their chemical composition, high-resolution near…
Chemical Abundances in the Milky Way's Nuclear Stellar Disc
N. Ryde, G. Nandakumar, R. Albarracin +3
The Nuclear Stellar Disc (NSD) is a rotating, disc-like structure in the Galactic Center, believed to have a distinct star formation. However, its formation history and evolutionar…
The First Chemical Census the Milky Way's Nuclear Star Cluster
Govind Nandakumar, Nils Ryde, Mathias Schultheis +4
An important step in understanding the formation and evolution of the Nuclear Star Cluster (NSC) is to investigate its chemistry and chemical evolution. Additionally, exploring the…
