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…
Detailed theoretical analysis of core Helium-burning stars: Mixed mode patterns I. Impact of the He-flash discontinuity and of induced semi-convection
L. Panier, G. Buldgen, M. Matteuzzi +4
Space missions like CoRoT, Kepler, and TESS have made asteroseismology a powerful probe of stellar interiors. Red giants are key targets thanks to their rich mixed-mode oscillation…
Predictions of gravity mode pulsations of collisional blue straggler stars in globular clusters
Lorenzo Briganti, Walter Eduard van Rossem, Andrea Miglio +2
Blue straggler stars (BSSs) are exotic objects, which, being the results of processes such as mass transfer, mergers, or collisions, are considered key objects in the study of thei…
Inferring the efficiency of convective-envelope overshooting in Red Giant Branch stars
Lorenzo Briganti, Marco Tailo, Edoardo Ceccarelli +6
The understanding of mixing processes in stars is crucial for improving our knowledge of the chemical abundances in stellar photospheres and of their variation with evolutionary ph…
Parametric models of core-helium-burning stars: structural glitches near the core
Massimiliano Matteuzzi, Gaël Buldgen, Marc-Antoine Dupret +3
Understanding the internal structure of core helium burning (CHeB) stars is crucial for evaluating transport processes in nuclear-burning regions, constructing accurate stellar pop…
DUETS: Setting expectations for asteroseismic binaries and binary products with synthetic populations
A. Mazzi, J. S. Thomsen, A. Miglio +5
Asteroseismology gives us the opportunity to better characterize binaries and their products, and shed light on their role in Galactic populations. We estimate occurrence rates, ma…
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…
Anomalously low-mass core-He-burning star in NGC 6819 as a post-common-envelope phase product
Massimiliano Matteuzzi, David Hendriks, Robert G. Izzard +5
Precise masses of red-giant stars enable a robust inference of their ages, but there are cases where these age estimates are highly precise yet very inaccurate. Examples are core-h…
The true nature of HE0057-5959, the most metal-poor Li-rich star
A. Mucciarelli, P. Bonifacio, L. Monaco +2
The Li-rich stars are a class of rare objects with A(Li) higher than that of other stars in the same evolutionary stage. Their origin is still debated and valuable routes are the C…
