Phosphorous in the moderately metal-poor bulge globular clusters NGC 6539 and NGC 6569
Morgan S. Camargo, Beatriz Barbuy, Heitor Ernandes +10
The distinct stellar populations of the Galactic bulge can be disentangled through detailed analysis of their chemical abundances and kinematical properties. Recent studies have su…
SMUGGLE-Ring: Evolutionary link between nuclear star cluster and nuclear disk
SungWon Kwak, Mathias Schultheis, Ivan Minchev +8
We present a high-resolution hydrodynamical simulation of the formation and evolution of nuclear structures in a Milky Way-mass galaxy using the SMUGGLE multiphase ISM and stellar…
Asteroseismic ages for 17,000 stars in Kepler, K2 and TESS
Emma Willett, Andrea Miglio, Saniya Khan +9
The availability of asteroseismic constraints for tens of thousands of red giant (RG) stars has opened the door to robust age estimates, enabling time-resolved studies of different…
The SMUGGLE-Ring project: Bar and bulge effects on nuclear disk and ring formation
SungWon Kwak, Federico Marinacci, Matthias Steinmetz +8
We present the first results from the SMUGGLE-Ring project, a suite of simulations employing the SMUGGLE ISM and stellar feedback model to explore nuclear structures in Milky Way-m…
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…
