The GALAH Survey: Neutron-Capture Elemental Abundances for 350,000 Gaia-RVS spectra and the Chemodynamics of Accreted Structures

Pradosh Barun Das, Daniel B. Zucker, Aldo Mura-Guzmán +15

We present a comprehensive data-driven spectroscopic analysis of 357,415 red giant stars using Gaia DR3 Radial Velocity Spectrometer (RVS) spectra (8460-8700 A; ),…

Searching for and characterizing halo substructures with the GALAH DR4 survey

Iryna Kushniruk, Kristopher Youakim, Karin Lind +12

Recent studies show that the Milky Way stellar halo is composed of populations of different origins, shaped by multiple accretion events. To better understand the formation of the…

Optical spectroscopic signatures of the red giant evolutionary state

Ella Xi Wang, Melissa Ness, Thomas Nordlander +17

Modern spectroscopic surveys output large data volumes. Theoretical models provide a means to transform the information encoded in these data to measurements of physical stellar pr…

The GALAH survey: Improving chemical abundances using star clusters

Janez Kos, Sven Buder, Kevin L. Beeson +18

Large spectroscopic surveys aim to consistently compute stellar parameters of very diverse stars while minimizing systematic errors. We explore the use of stellar clusters as bench…
