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…
Tracing back a second-generation star stripped from Terzan 5 by the Galactic bar
Stefano O. Souza, Marica Valentini, Cristina Chiappini +6
The Galactic bulge hosts the Milky Way's oldest stars, possibly coming from disrupted globular clusters (GCs) or the bulge's primordial building blocks, making these stars witnesse…
Age dissection of the Milky Way discs: red giants in the Kepler field
Andrea Miglio, Cristina Chiappini, Ted Mackereth +16
[Abridged] Ensemble studies of red-giant stars with exquisite asteroseismic, spectroscopic, and astrometric constraints offer a novel opportunity to recast and address long-standin…
The CoRoT-GES Collaboration. Improving Red Giants spectroscopic surface gravity and abundances with asteroseismology
M. Valentini, C. Chiappini, A. Miglio +4
Nowadays large spectroscopic surveys, like the Gaia-ESO Survey (GES), provide unique stellar databases for better investigating the formation and evolution of our Galaxy. Great att…
The Radial Velocity Experiment (RAVE): Fifth Data Release
Andrea Kunder, Georges Kordopatis, Matthias Steinmetz +51
Data Release 5 (DR5) of the Radial Velocity Experiment (RAVE) is the fifth data release from a magnitude-limited (9< I < 12) survey of stars randomly selected in the southern hemis…
Does the chemical signature of TYC 8442-1036-1 originate from a rotating massive star that died in a faint explosion?
G. Cescutti, M. Valentini, P. François +4
Context. We have recently investigated the origin of chemical signatures observed in Galactic halo stars by means of a stochastic chemical evolution model. We have found that rotat…
Galactic Archaeology with CoRoT and APOGEE: Creating mock observations from a chemodynamical model
F. Anders, C. Chiappini, T. S. Rodrigues +8
In a companion paper, we have presented the combined asteroseismic-spectroscopic dataset obtained from CoRoT lightcurves and APOGEE infra-red spectra for 678 solar-like oscillating…
Galactic archaeology: mapping and dating stellar populations with asteroseismology of red-giant stars
A. Miglio, C. Chiappini, T. Morel +11
Our understanding of how the Galaxy was formed and evolves is severely hampered by the lack of precise constraints on basic stellar properties such as distances, masses, and ages.…
An abundance study of the red giants in the seismology fields of the CoRoT satellite
T. Morel, A. Miglio, N. Lagarde +11
A precise characterisation of the red giants in the seismology fields of the CoRoT satellite is a prerequisite for further in-depth seismic modelling. The optical spectra obtained…
