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…
Pushing the boundaries of asteroseismic individual frequency modelling: unveiling two evolved very-low metallicity red giants
Jens R. Larsen, Jakob L. Rørsted, Victor Aguirre Børsen-Koch +21
Metal-poor stars are key to understanding the first stellar generation in the Galaxy. Asteroseismic characterisation of red giants has traditionally relied on global seismic parame…
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…
Red giants evolutionary status determination: the complete Kepler catalog
M. Vrard, M. H. Pinsonneault, Y. Elsworth +12
Evolved cool stars have three distinct evolutionary status: shell Hydrogen-burning (RGB), core Helium and shell Hydrogen burning (RC), and double shell burning (AGB). Asteroseismol…
The APO-K2 Catalog. II. Accurate Stellar Ages for Red Giant Branch Stars across the Milky Way
Jack T. Warfield, Joel C. Zinn, Jessica Schonhut-Stasik +11
We present stellar age determinations for 4661 red giant branch stars in the APO-K2 catalog, derived using mass estimates from K2 asteroseismology from the K2 Galactic Archaeology…
