Abstract:
The detection of oscillations with a mixed character in subgiants and
red giants allows us to probe the physical conditions in their cores.
With these mixed modes, we aim at determining seismic markers of
stellar evolution.
Kepler asteroseismic data were selected to map various evolutionary
stages and stellar masses. Seismic evolutionary tracks were then drawn
with the combination of the frequency and period spacings.
Description:
Seismic global parameters of the stars listed in the paper. Each star
is identified with its KIC number (Kepler Input Catalog).
The asymptotic frequency and period spacing are derived from the fit
of the radial and dipole oscillation modes. The stellar mass is
derived from the seismic scaling relations. The evolutionary status is
derived according to the location of the star in the DPi1 - Dnu
diagram (Fig. 1)
