The high-altitude, inner-disc, and chemically peculiar open cluster UBC 1052

Judit Donada, Laia Casamiquela, Friedrich Anders +8

Out of all the discovered open clusters (OCs) that are located in the inner part of the Galaxy, only a small fraction has been observed with high-resolution spectroscopy. An intrig…

Advancing accuracy in age determinations of old-disk stars using an oscillating red giant in an eclipsing binary

J. S. Thomsen, A. Miglio, K. Brogaard +26

The study of resonant oscillation modes in low-mass red giant branch stars enables their ages to be inferred with exceptional (10%) precision, unlocking the possibility to re…

Gaia FGK Benchmark Stars: spectral library, metallicities and abundances of and Fe-peak elements of the third version

L. Casamiquela, C. Soubiran, P. Jofré +14

The accurate determination of chemical abundances in stars plays a pivotal role in understanding stellar structure and evolution, nucleosynthesis, and the chemical enrichment histo…

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…

Full abundance study of two newly discovered barium giants

Sara Vitali, Ana Escorza, Ditte Slumstrup +1

Barium (Ba) stars are chemically peculiar stars that show enhanced surface abundances of heavy elements produced by the slow-neutron-capture process, the so-called s-process. These…

Stellar Models are Reliable at Low Metallicity: An Asteroseismic Age for the Ancient Very Metal-Poor Star KIC 8144907

Daniel Huber, Ditte Slumstrup, Marc Hon +15

Very metal-poor stars ([Fe/H]<-2) are important laboratories for testing stellar models and reconstructing the formation history of our galaxy. Asteroseismology is a powerful tool…
