The PLATO Science Calibration and Validation Plan: Targets for the First Long-pointing Field
Konstanze Zwintz, Conny Aerts, Andrew Tkachenko +56
In order to meet the science goals of the PLATO space mission, an extensive science calibration and validation plan has been designed. This paper describes this plan, as well as th…
Large-scale time-series spectroscopy for stellar ages
David Gruner, Sydney A. Barnes, Ansgar Reiners +16
To date, Galactic Astronomy has largely concerned itself with astrophysical processes, and with the locations, space motions and compositions of objects. Consider, for example, the…
SDSS-V Milky Way Mapper (MWM): ASPCAP Stellar Parameters and Abundances in SDSS-V Data Release 19
Szabolcs Mészáros, Paula Jofré, Jennifer A. Johnson +25
The goal of this paper is to describe the science verification of Milky Way Mapper (MWM) APOGEE Stellar Parameter and Chemical Abundances Pipeline (ASPCAP) data products published…
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…
