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…
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…
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…
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…
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…
