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 model. The system naturally…

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…

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…

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…
