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…
Attempting an accurate age estimate of the open cluster NGC 6633 using CoRoT and Gaia
K. Brogaard, A. Miglio, T. Arentoft +5
Asteroseismology of solar-like oscillations in giant stars allow the derivation of their masses and radii. For members of open clusters, this provides an age of the cluster that sh…
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…
Tracing the Milky Way: Calibrating chemical ages with high-precision Kepler data
G. Casali, J. Montalbà n, A. Miglio +10
Chemical clocks offer a powerful tool for estimating stellar ages from spectroscopic surveys. We present a new detailed spectroscopic analysis of 68 Kepler red giant stars to provi…
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…
