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…
Rediscovering the Milky Way with orbit superposition approach and APOGEE data III. Panoramic view of the bulge
Sergey Khoperskov, Paola Di Matteo, Matthias Steinmetz +9
The innermost parts of the Milky Way (MW) are very difficult to observe due to the high extinction along the line of sight, especially close to the disc mid-plane. However, this re…
Rediscovering the Milky Way with orbit superposition approach and APOGEE data II. Chrono-chemo-kinematics of the disc
Sergey Khoperskov, Matthias Steinmetz, Misha Haywood +9
The stellar disc is the dominant luminous component of the Milky Way (MW). Although our understanding of its structure is rapidly expanding due to advances in large-scale stellar s…
Rediscovering the Milky Way with orbit superposition approach and APOGEE data I. Method validation
Sergey Khoperskov, Glenn van de Ven, Matthias Steinmetz +9
We introduce a novel orbit superposition method designed to reconstruct the stellar density structure, kinematics, and chemical abundance distribution of the entire Milky Way by le…
Effects of secular growth and mergers on the evolution of metallicity gradients and azimuthal variations in a Milky Way-like galaxy
Florent Renaud, Bridget Ratcliffe, Ivan Minchev +4
We analyze the evolution of the radial profiles and the azimuthal variations of the stellar metallicities from the Vintergatan simulation of a Milky Way-like galaxy. We find that n…
New stellar age estimates using SPInS based on Gaia DR3 photometry and LAMOST DR8 abundances
L. Casamiquela, D. R. Reese, Y. Lebreton +8
Reliable stellar age estimates are fundamental for testing several problems in modern astrophysics, in particular since they set the time scales of Galactic dynamical and chemical…
