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…
Extra modes in helium-core-burning stars probing an infra core cavity
B. Mosser, M. Takata, C. Pinçon +5
Dipole mixed modes observed in the oscillation pattern of red giant stars probe the radiative regions in the stellar core. Oscillation spectra of helium-core-burning stars sometime…
Physical interpretation of the oscillation spectrum on the RGB and AGB
G. Dréau, Y. Lebreton, B. Mosser +1
The high-frequency resolution of the four-year time series allows detailed study of seismic modes in luminous giants. Seismic observables help infer interior stru…
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…
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…
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…
