Chemical Abundances in the Nuclear Star Cluster of the Milky Way: alpha-Element Trends and Their Similarities with the Inner Bulge

N. Ryde, G. Nandakumar, M. Schultheis +15

A chemical characterization of the Galactic Center is essential for understanding its formation and structural evolution. Trends of alpha-elements, such as Mg, Si, and Ca, serve as…

Metallicity-dependent kinematics and orbits in the Milky Way's nuclear stellar disc

F. Nogueras-Lara, N. Nieuwmunster, M. Schultheis +7

The nuclear stellar disc (NSD) is a flat and dense stellar structure at the centre of the Milky Way. Previous work has identified the presence of metal-rich and metal-poor stars in…

A Wide Metallicity Range for Gyr-old Stars in the Nuclear Star Cluster

Brian Thorsbro, Rebecca Forsberg, Georges Kordopatis +6

We report metallicities for three Gyr-old stars in the Milky Way nuclear star cluster (NSC) using high-resolution near-infrared spectroscopy. We derive effective temperatures…

Composition of Giants 1 North of the Galactic Center: Detailed Abundance Trends for 21 Elements Observed with IGRINS

Govind Nandakumar, Nils Ryde, Gregory Mace +10

We report the first high resolution, detailed abundances of 21 elements for giants in the Galactic bulge/bar within of the Galactic plane, where high extinction has rende…

M Giants with IGRINS III. Abundance Trends for 21 Elements in the Solar Neighborhood from High-Resolution, Near-Infrared Spectra

G. Nandakumar, N. Ryde, R. Forsberg +4

In order to investigate the chemical history of the entire MilkyWay, it is imperative to also study the dust-obscured regions, where most of the mass lies. The Galactic Center is a…
