High-precision abundances of elements in Kepler LEGACY stars. Verification of trends with stellar age
P. E. Nissen, V. Silva Aguirre, J. Christensen-Dalsgaard +3
HARPS-N spectra with S/N > 250 and MARCS model atmospheres were used to derive abundances of C, O, Na, Mg, Al, Si, Ca, Ti, Cr, Fe, Ni, Zn, and Y in ten stars from the Kepler LEGACY…
Confirming chemical clocks: asteroseismic age dissection of the Milky Way disk(s)
V. Silva Aguirre, M. Bojsen-Hansen, D. Slumstrup +22
Investigations of the origin and evolution of the Milky Way disk have long relied on chemical and kinematic identification of its components to reconstruct our Galactic past. Diffi…
The [Y/Mg] clock works for evolved solar metallicity stars
D. Slumstrup, F. Grundahl, K. Brogaard +5
Previously [Y/Mg] has been proven to be an age indicator for solar twins. Here, we investigate if this relation also holds for helium-core-burning stars of solar metallicity. High…
NGC 6819: testing the asteroseismic mass scale, mass loss, and evidence for products of non-standard evolution
R. Handberg, K. Brogaard, A. Miglio +5
We present an extensive peakbagging effort on Kepler data of 50 red giant stars in the open star cluster NGC 6819. By employing sophisticated pre-processing of the time serie…
