Not all nitrogen-rich field stars originate from globular clusters
Ellen I. Leitinger, Andrea Miglio, Josefina Montalbán +7
Globular clusters (GCs) are important tracers of the early Galactic assembly process, with part of their stars showing distinct chemical abundance patterns. When such stars are fou…
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…
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…
Connecting integrated RGB mass loss from asteroseismology and globular clusters
K. Brogaard, A. Miglio, W. E. van Rossem +2
Context. Asteroseismic investigations of solar-like oscillations in giant stars enable the derivation of their masses and radii. For mono-age mono-metallicity populations of stars…
