TwinSpecNet: Extending APOGEE's chemical reach to low-S/N spectra via empirical paired learning
Weijia Sun, Cristina Chiappini, Samir Nepal
Large spectroscopic surveys rely on automated pipelines to deliver homogeneous stellar labels, but a substantial fraction of observations are at low signal-to-noise ratio (S/N), wh…
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…
Ancient relic moderately metal-rich bulge cluster Tonantzintla 2
Sergio Ortolani, Stefano O. Souza, Domenico Nardiello +6
The assembly history of the Galactic bulge is intimately tied to the formation of the proto-Milky Way, yet reconstructing this early phase is difficult because mergers and secular…
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…
