Rediscovering the Milky Way with an orbit superposition approach and APOGEE data V. The disc growth and history of star formation
Bridget Ratcliffe, Sergey Khoperskov, Nathan Lee +8
The Milky Way's (MW's) star formation history (SFH) offers insight into the chronology of its assembly and the mechanisms driving its structural development. In this study, we pres…
Bar-spiral interaction produces radial migration and star formation bursts
Léa Marques, Ivan Minchev, Bridget Ratcliffe +8
Central bars and spirals are known to strongly impact the evolution of their host galaxies, both in terms of dynamics and star formation. Their typically different pattern speeds c…
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…
The chemical evolution of the Milky Way thin disk using solar twins
Anastasiia Plotnikova, Lorenzo Spina, Bridget Ratcliffe +2
In this study we address whether the age--metallicity relation (AMR) deviates from the expected trend of metallicity increasing smoothly with age. We also show the presence (or abs…
